This is an old challenge now, this thread is archived. If you scroll down to the Challenge #14 section of the downloads page, you'll see that the models can still be downloaded for your tests, and also that a gallery has been made of top entries. Feel free to browse this thread to see what others have posted, even though you can no longer post here.

Trains run all over the world. The challenge here is to render this train so that it appears to run through your own home town.

Challenge #14 is on-line and active! You can download files from this page:



http://www.3drender.com/challenges/


The Local Idea:

You are capturing the feeling of your local town. The train doesn't necessarily have to run in a location where there actually are train tracks at the moment, especially if you can think of a more scenic route where a train could run.

Any texture maps (particularly signs, lettering, or logos) that you map onto the train or signals should be based on what would appear in the city or town where you live. Try using a camera to photograph local trains for reference and texture maps, and also get some shots in your town for a background/environment.

An untextured view of the scene by Alvaro Luna Bautista.




The Scene:

This scene was modeled by Alvaro Luna Bautista. Please credit him for his work if you use images of this train on your webpage or showreel.

The scene includes a number of extra buildings, signals, and surrounding models. Try to use some of the buildings in your scene if you can find a place for them. To achieve a "local" look, you are free to change the geometry around as needed.

The ground and all the little stones on the ground were positioned to look good from one particular camera angle, as shown above in Alvaro's rendering of his own scene. You can match this camera angle if you want to use the stones as they are distributed, or else change the ground and ground-cover if you are rendering from a different camera angle.

Feel free to add whatever kind of grass, plants, or vegetation would be appropriate for your home town.

Deadline:

Post your work here by March 31, 2008 to be eligible for the initial gallery selection. The scenes will still be available after that date as an on-going challenge for people who wish to try this as a lighting and rendering excercise.

I should really try to get time to do this one seeing as how I spend 2½ hours per day going back and forth to my 3D job :P I'd have to change alot since the scene atm has alot of american trainyard feel to it, not really looking like sweden :)
But then again, Ive had plans to enter almost every challenge but just didnt find the time, so we'll see...

As always, more file formats are welcomed! If there are people who want to volunteer to make 3DS Max, Lightwave, Cinema 4D, and or other format versions, please contact me. I'll take your additional file versions and host them.

Usually we get more formats in the first week, depending on who does it, but until more versions are added I think the .fbx or .obj should import fine into Max. The .fbx might even preserve the object grouping.

it's a .ma file, you can open it in note pad and edit the version of the file in the first few lines.... it's not a small file so it might take some time to open in note pad.

A tip for people using mental ray, the gravel is quite 'slow' in terms of overall render speed (exporting and BSP at least) because it's hundreds of individual items. If you do a Mesh > Combine on them all and then delete the history, you should get a 55% speedup on them as I did. In the end I'll probably go for displacement instead though.

I replaced the stones with a particle flow system. It's quite a bit faster in Max, and gives you more camera freedom as well as a nice fast viewport preview...

That's a good tip. Merging the gravel into one object could be more efficient.

If you're going to delete the stones, I'd keep at least a few of them around. Even with displacement mapping on the ground, the ground is more believable if you can set-dress a few real rocks and debris and plants around as well. When I've had ground surfaces with a liberal amount of real rocks scattered around on the model, I've had people stop and say "wow, that's a nice ground shader" as if they are seeing the rocks as non-scalar displacement or something.

If download the .obj format, I have the scene split into a series of .obj files this time, with the stones in a separate file. So for people with limited RAM, importing the stones is optional.

Thanks to jmBoakestein and MartinRomero, we now have a 3D Studio Max version of the file on the download page.

Any other formats people want me to host?

Anyone with Cinema 4D or Lightwave or other popular software want to contact me and offer a converted file?

The "Local Train" file for Maya opens only in Maya 2008. I tried it on both of my computer in Maya 8.5 but it didn't open.
In Maya 8.5, if you click the options box next to Open Scene... you can check "Ignore Version" so it'll open files saved in a newer version of Maya. I think this option was added in 8.5. In Maya 8 and earlier you still had to open the .ma in a text editor and delete or modify the "requires" lines. (Although earlier Maya versions can import the .obj or .fbx without any need to change them...)

Jeremy, you mentioned photographing local trains for reference/textures. While that's a good idea, I feel that someone should put in a word about safety. There's a simple rule to follow when photographing railroads:

STAY OFF THE TRACKS!

It is possible for a train to approach you from behind without you hearing it, especially if you're concentrating on your camera. People have been killed this way.

The tracks, and the land adjacent, belong to the railroad. These days, railroads do not take kindly to trespassers, even ones with cameras. Unless you are certain that a section of track is abandoned, or you have special permission, stay off of railroad property. Take your photographs from public or non-railroad private property.

Stay safe, and stay out of jail.

Great start to the challenge! The daytime image looks more bright and sunny than the background shot, at least the sky in the background could be a lot brighter and the building could have some more brightness and contrast as well. I think the daylight scene could use more environment reflections, on the train and glass especially could reflect the sky more. The night scene is good, maybe the bright areas could be more localized and there could be more lights glowing on-screen to justify how bright it all looks. The cabin interior will need a new surface on the night scene if it remains that visible.

Hi, Samo
thanks for the website. I live in India and if you look at the engines from my part of the world, they all have the lights off in day time. could be that its a european law or something?.

Maybe some few countries don't follow this rule, but most of them do, at least in the American continent and Europe. I've checked that site and, in some Asian countries, locomotives don't have their head lamps on in day time.

And by head lamps I mean only the two big frontal lights.

02-13-2008, 02:53 PM
lighthunder - Good start! For the area that's in shadow (outside of direct sun) it would be good to get some variety in the shading and hopefully some occlusion. A nice mix of shadow and sun helps the composition. See if you can use a more interesting background than pure sky, so we really see where we are from what's built at the the horizon line. As you add to the texturing making some things look a little more dusty and less clean and new would be a good goal.

ShamKiR - Welcome! Good start. Usually if you are lighting a scene with just one main light, I'd try to put the light a little more off to one side or the other, so it doesn't light things straight-on. Coming from a bit more of an angle helps define the shape of things better and makes less symmetrical shadows.

tuffmutt1 - Better and better! I love the way you're going with the dust and dirt on top of the train, and it's starting to get more of a sense of place. You have a lot of depth in the shot, and it seems that what's more distant in the buildings are bright and not very saturated. Maybe the electical pole behind the train could be a little more towards light gray -- the pole itself is already like that, but the top cross-peice looks like a deep reddish color and doesn't appear as distant and washed-out as it could, to establish that it is half way from our foreground into the background. For that little shack, the texturing doesn't seem to respond to the little window, maybe delete the window from the geometry and have a plain wall? The lighting on the shack looks too uniform, I think the left side should be brighter than the side facing camera. I like the foreground vegetation, too. A tiny bit of that could be put in the more distant parts in the lower left and maybe a little vegetation of some kind could be visible accross the tracks near the right wall? The construction materials stacked in a regular grid in the foreground could use a little variation or maybe could be fitted together more closely?

mJunaidb - Welcome! Good start! Maybe with texturing and a different background image it will look more like Pakistan. You basic light direction and camera angle looks good. Maybe the composition could be improved if you widened the aspect ratio so the front of the train was visible instead of cropping it so close to the front.

Hi,

This is my version of this scene. I'm working with the default view.
I'm still figuring out what solution to use to add bushes to the scene without compromising more the file size.

Modelled with Blender.
Rendered with YafaRay. Just a Sun light, a gradient background, pathtracing.
Render took about 45 min. in a 2.4 Pentium - 512 RAM
Textures made with Inkscape and The Gimp.

Samo: I don't know if you've heard of or seen the video game Team Fortress 2 by Valve. Your image has a very similar feel to it. Great start I'd like to see some variation in the texturing and reflectivity and some sort of vegetation like you were saying. If you really need to keep the poly count down you could always use a series of transparent images on planes. Keep it up!

jeremybirn
02-15-2008, 03:01 PM
dboydesign - Do what you need to.

Samo - Sooner or later you'll probably need to render in layers and composite. Maybe you could start with a background picture to set the scene in Spain. The easiest of all compositing approaches is to split the scene into foreground, mid-ground, and background, so one layer just goes over the previous layer. That way you don't need to render all the trees and shrubs in the same layer as the train and gravel. Things are simplest if the objects that need to shadow and reflect eachother are in the same layer, although I'm sure your software can be used to render things as separate passes if you need to. Another direction to head would be to work more on texture mapping, making the train and tracks look less clean and perfect, more like a train in Spain, and really nail that side of things before you add more models to the scene.

Those are great! Focusing on the initial set-up of the daytime ones: I think the lighting could match better between the foreground (CG) and the background (image). The foreground has lots of dark tones and black blacks, the background never gets nearly that dark. If the background were a little lighter, it could be haze or atmospheric perspective, but this is a bigger difference than that. The background is lit very brightly, the foreground (apart from the roof of the hut) doesn't have such broad, soft, bright illumination. The background seems to be lit from the front, left side, you can see some buildings and trees are brighter on the left. The foreground needs to match the sun direction of the background.

If you split the foreground rendering into passes, it's sometimes easier to nail all the values. Render one pass of sky-fill, just soft cool light on everything, hopefully with some occlusion. Render a separate occlusion pass if there isn't occlusion in the sky fill layer, and multiply them in the comp. Then render a sun light pass. This might be 2 passes if you separate the specular from the diffuse sun illumination. Then render reflections if there are sky/environment reflections. Then you can add these passes together and adjust their brightness and color until they really match all the tones from the background.

The perspective match is pretty good. It looks as if the train is heading up a hill. That impression is alright if it's intended, but then you need to think about making the posts and signals go straight up, instead of looking like they are perpendicular to the surface of a slanted ground surface.

All those other experiments based on it are nice, and your night scene really looks terrific. I think you could do another take on the basic daytime match-lighting though to really get it 100% perfect.

A little more about your night scene: it looks great. It's funny that you call it "a bit stylized" and I would call it very realistic -- maybe I've just been working on stylized movies for too long. :) Anyway, it looks terrific in terms of colors, tones, and optical effects. I think the left and right edges of the image could be changed to better frame it. Maybe on the left, that blue highlight on the water tower looks a little bright and fake. You could replace it with a rectangular reflection that is dimmer and runs up and down the whole tank. On the right, that row of signs looks too bright to me, and it's not clear where the light exists in 3D space compared to the power lines and fence, it looks somehow as if it should be closer based on the perspective. You could get rid of that whole lamp, or else make it into a darker form against the sky.

Hello Jeremy and everyone!

Time for an update.

I have nearly figured out how and where the scene will be. Unfortunatelly I have never travelled with long distance trains in Greece and I dont have any train stations nearby, so what I will try to do is based on two photos of Greek stations I found on the net.

I uploaded some Renders of the Basic Train Part which I textured today. It is not completely finished ( needs more work on the Windows and a few minor details) but most of it its there.

I wanted to play with rust coz I just love it. I now I may have overdone it but it is part of my scenario and composition.

Uv layouts in Maya - Main Textures and signs in Photoshop and Procedural Rusts and Final Shading in Maya again.

Rendered with Mental Ray, with just a basic HDRi setup.

Unfortunatelly I used very high resolution texture files and cannot render it anymore (only batch) so I will have to lower the quality a bit.

Thanks for watching. :)

hi Jeremy. thanks for the detailed critic. i ve given it another go with some passes this time.

the diffuse pass didnt work well because og the opacity maps in the vegetation.
this is a irritatating problem for me. may be some one has a solution for it...might be helpful.
heres a sample of the prob. i am using mental ray.

hi all,

here is my try. I want an early morning maybe i thought about snow and very hazy sunlight. But that volumetric stuff isnt right implemented in vrayforc4d. So later i will spend some time with ar2 and postwork to make such an effekt... My very next steps are beginning in Texturing the train and the hole scene. Before that i have to clean up the scene for cinema4d. I will spend some time on getting some nice wood in the picture, so creating some uvw would eat some time :). I will make that train yellow, this red was just a test and im really unhappy with it! So the weekend can come. greetings from cologne germany :)

this is my first try to my very first challenge :). I'm not quite sure about the background yet, I tried to recreate one of the bridges running all over my hometown (Berlin, Germany) on which the main railroads and urban rails are placed. Because of the whole electrical wiring and stuff i had to make quite some changes to the environment. CC always welcome!

tuffmut:
Nice job on your renders! It's awesome that you can get stuff like that out so quickly! My only crit would be that, for some reason, your render comes out looking like it's fake. Fake in the sense that, when I look at it, your train and the objects around it, look like something out of a toy train set.
What I'm beginning to think is that it has to do with the textures that you have on your objects. I think you need to work on some specular, translusency, and reflection maps. Really study the material you are using and how it acts realistically. It'll really help if you add that aspect into your render.

Hope I was somewhat helpful. :)

gattaca13
02-25-2008, 05:37 PM
Leonikou,
Nice job on the train! Looks like you're moving in the right direction. I have some tips for you though to help you improve it a bit. :)
You need to massage your UVs more in certain areas. There is some texturing stretching on areas where there are indentions and extrusions in the train. Also, the black on the windshield is a little odd. It's hard to tell what it is. The bump is really high on it as well which makes it look more awkward. Work on your specular map a bit. For the train supposing to be really old and rusty looking, it is very shiny. I would definitely turn it down.


That's all I got for now. Hope it was helpful. :)

Leonikou
02-26-2008, 08:44 AM
shamKiR- Thanks mate!

gattaca13 - Yes, I know that the train could use more love, and it is already been taken care off. :)

You know, I'm really loving the train, and all the possibilities for this challenge, but jesus guys, not everyone has a quad core processor. It's like working with shattered glass. The file is so huge my system keeps glitching and lagging. I have to save every two minutes because Max keeps wanting to crash if i do anything more than one thing at a time.

You think for the next challenge we could use a few less polys?

I am 100% agree with you.
I have the pc for work with this kind of files in my office, it goes perfect, but in my house the pc is nos as good as the other, and this file keep crashing, i also think the scene has waaaay to much polygons, is really heavy, i think it would be cool to work on that for the people dont have a pc for this kind of files.

But still loving this scene, my render soon ;).

The Blender file in Jeremy's page is the original one. I don't know if you have some experience in Blender, but in the Blender scene there are many object that have a level 2 subdivision surfaces (mainly they are the locomotive parts), and there are also the ballast stones. The scene has been modelled in a PIV with a 32 RAM Geforce 3, although Blender is really good handling scenes with big poly counts.

The point I'm trying to make is that if you reduce to level one subsurf and export again to the needed format, or maybe exporting without the subsurf modifier and aplying later in your own app. you can sort out partially the file size problem. Blender have quite a lot export options.

Anyway I think that dealing with this issue can be one of the challenges of this scene, because you will find that problem again when figuring out how to add plants to the scene for instance, or using you own ballast solution.

I can work on a light weight version if you need it. Maybe without ballast and with loco parts without subsurf modifier, to apply later in your own software. Tell me if you need it.

Samo
02-26-2008, 08:32 PM
Ok this is a light blender version of the scene. All subdivision surf. modifiers and the ballast stones have been removed.

http://www.megaupload.com/?d=Y282Z0VI

If your software does not support subdivision surfaces, then apply subsurf before exporting. I think only the locomotive main mesh need subsurf and maybe some other locomotive parts (doors and round windows frames). Send me a private missage if you need help about how to apply subsurf in Blender, anyway here there is some info.

http://wiki.blender.org/index.php/Manual/Subsurf


Maya users should use "objects groups" option in the OBJ export panel to get separated meshes.

teq
02-26-2008, 11:19 PM
The very first thing I did was sit down and break the whole thing into 15 or so layers. Now I can leave 90% of the scene hidden while working and everything runs nicely.

02-26-2008, 11:47 PM
Thanks Samo, I was using the original obj file and my computer choked when loading the train. I exported the new scene from Blender as a obj file came in at around 62,000 and as a test I loaded the whole scene no problem in Daz|Studio. the D|S saved scene is only 118kb, go figure. anyway i'll be working on it in a different program and thanks again because it is a great scene. :)

@fed: superb light mood!
u need a bit more bounce or ambient light on the right side of the train.
I think the strong depth of field generates a bit of a macro look, i would lower it a lot.
Keep going that could be a masterpiece:)

I've added a background to my render, although colors don't match very well and it needs color correction, in the mean time here you have a low res. B/N version:

Rendered with YafaRay, pathtracing, sunlight + fill light + background.

I think I'm going to explore other camera views.

Maybe some snow on the ground and more reflexions on the glass textures.
If you still try, be careful to keep this wonderful ambiance.

In the middle hole of the train there are modelled a couple of lamps. In you scene I would use a subtle blue fill light coming from the right to simulate moon light. There could be also other light sources in the dark side of the image. This is how one of these locomotives can look like at night,

Final version (maybe), I like the light effect on this picture (http://www.railpictures.net/viewphoto.php?id=10908&nseq=47) , but I'am afraid that it will kill the render "ambiance", what do you think ?

FeD, between the first and the last three goods cars, I put some dummy cars that weren't going to be seen from the camera I had planned for this scene and from whom I only wanted them to cast shadows. If these dummy cars are eventually to be seen from your camera view, then maybe is better to remove them and clone the detailed goods cars (first and last three). If you watch your render closely you ll see the dummys cars have different surface properties that the detailed ones.

BTW great render.

Since I live in DC I thought it would be fun to see the train in the National Gallery. (The space is a really rough approximation of one of the gallery spaces.)

Anyway, here's the WIP, it's just some simple lighting and materials so far. The space was done in SketchUp, the tree's an onyx tree. It's rendered in Max 9 using mental ray with A&D materials. So far I'm only using the MR sun and sky to light the scene.

TEQ, I would use a bit stronger and warmer sunlight to burn a bit more the scene, now it seems like a cast day, well... it's Germany, but now the ligting is a bit ambiguous in your scene.

LIGHTHUNDER, I would definitely try a different background, it is particularly the low part of your background which seems a bit off. I would add also detail to that structure that is hanging above the train. In railpictures.net you will find a lot of inspiration for train related stuff and backgrounds.

Leonikou
03-07-2008, 09:32 AM
mirmel - I know what you mean. I could not go through the end with 100% correct Uv's so I did the basic train Lines based on Uv layout and the rest of the train using procedural 3DTexturing techniques (in Maya though.). Maybe try that.

teq - Nice progress so far, the camera angle and most of the elements, like the pillars look solid. I can see that the light is coming from the upper left corner right now, but it kind of washes out the image. I mean there are no hard or dark shadows and that has an impact especially on the houses in the back.Maybe change the light angle or compensate the cloudy day with more diffused bounce light spreading around.(Bring up the contrast in a way.) Perhaps use an occlusion and maybe some more bluish tint from the sky. Sorry for all these comments, but I think it can be a very nice render! :) Keep it up!

lighthunder - I like the sky, and the nice warm yellow feel of the sun in your render. You have nice amounts of Direct and indirect light so if you added an occlusion pass in your image it would bring it up a lot! The bump on the tunnel material I think is too much and there is something weird going on above the tunnel.Is that supposed to be protection bars for the pedestrians? If it is I think it can be out of scale my friend.
Lastly some more specular and metalic feel would bring up the image too, it looks more like a diffuse pass right now. Hope I helped a bit. Keep it up :thumbsup:

Thanks Teq, I'm just working on maya with the original model from the obj format.
.. I would ask you only for a tips to do uvs in simple and faster way. (I did an automatic mapping on half mesh and now I'm matching the uvs manually).. but maybe that is the only way :)

thanks for all the cc guys I really appreciate it.

I am trying to go for a cloudy day with very much diffuse light and only a little direct light. I know that this quickly looks "boring" or flat but I think it is what resembles my hometown best. (of course we have sunny days too ;) ). Right now I am quite unhappy with some of the materials (the House!) and the position of the main lights. So expect quite a few changes to come. Also I could think about a night scene which I think would be interesting because of the everywhere overlaying diffuse artificial light you have in every big city. (Never really dark here)

Hello Everyone. Time for an update.

I found some time to build some extra models for the station set, including some texturing.

The back Tunel is based on some photos of Patras station in Greece.

It still needs some more details,like leaves ,trees ,some garbage, signs, proper textures etc.

I have also got to fill the back and upper left part of the frame. Some more environment modelling propably.

The lighting is still being tested until I find the proper sky.

Commets are always welcome. Please let me know what you think :)

Thank you

- Leo

jeremybirn
03-08-2008, 04:27 PM
So much amazing work has been posted while I was not replying! I will try to catch up!

Leonikou - Beautiful image! A few areas could use more bounce/fill light: the tops of the ties (the wooden cubes under the metal tracks), the inside of the tunnel (the tunnels on the right have a little light coming into them, so the left tunnel would also), any other place going too close to black. The reflections in the glass could be brighter on the window of the shack and the left side of the train window, but maybe are a little too bright on the right side of the train's front window. You could punch-up the front of those buildings to make them really look like sunlit brick getting hit from the side, you might need some bump or displacement to do it but then they wouldn't look flat. You barely notice that lovely ocean in the background, maybe if there were a way to make more of the ocean visible that would help the scene look distinctly Greek.

Shordy - Nice scene. So where are you from? I can't tell what kind of local scene you are making, and your profile doesn't say the location. That's a nice scene. I can't tell for the surface to the right of the train if it's supposed to be water with funny creases in it, or some kind of mud turning into water? The scene right now looks like a miniature, like a toy train set, but probably the forced depth of field blurring is responsible for that feeling, but also it comes from the lack of detail such as vegetation around areas like the left side of the image.

Still catching up, here's some more feedback on the images from the past few pages:

Samo - That's great. I love the black and white scene. If the rails are going to be reflective, it should be a soft reflection, not a crisp one. The windows of the train should reflect the sky a little though, and the black circle around the headlights also needs some reflection or fill or something to give it presence. The gravel in the lower right corner doesn't look like it has the directionality of light coming from the left as much as other parts of the scene, you might add a little extra kick there. That little shack also needs some reflections on the windows.

FeD - That's a great scene, and thanks for posting the breakdown of the render layers. The textures on your train look great. Maybe the bump/specular influence of the cracks make them look too soft and deep, you could turn that down a little. The sunlight leaking through onto the right-side wheels doesn't look entirely believable to me. Maybe there should be more train shadow blocking most of that, and glints of light on that side could be more due to reflections and bounce light? The right side of some things could use more sky fill, or at least some sky reflection on the fill side of the metals and glass. I agree with your comment about looking far away from France; the scene doesn't look distinctly French.

tuffmutt1 - That's great! It has a nice feeling, even if it doesn't look recognizably Indian to me. I love the depth and dimensionality of the space. Even in your newer version (#102) some of the posts to the power lines still have a black outline around them, especially on the left, that looks like it could be a compositing problem if it isn't a lighting problem. Now that you've added light to the right side, you need to get some more texture work done on the tree and fence, and get the leaves of the tree to look back-lit.

wadefuh - That's a great idea. I'd love to see it come to life as a real train there. Your set-up with the real train and the model in the case is interesting.

rameshganga - Great scene. I think the focus doesn't match between the CG and the background, but the perspective is very good. You'll need to light the utility poles to match the poles in the photograph, and maybe also scale them bigger? I'd love to see some reflections on parts of the train that are still gray. The gravel looks pretty good, but gets blurred in places and some stones could have fallen onto the ground in the foreground. The plant in the lower left has compositing issues, especially where it intersects with the little building. Keep going!

teq - Looking good! I think the background needs some haze or atmosphere fading in with distance, so the silos in the background don't look so contrasty. The tracks and stones are looking good, except that the stones seem to repeat a little too much in places. Keep going with the texturing!

lighthunder - Nice scene. Others have given you good feedback already. Remember you don't need to see into the train, the window can just be reflective. I think the window on the side of the little house could be deleted if it doesn't fit with the advertising panel you want there. I wish we could see more of the water tower with the nice sign mapped onto it, that gives a distinctly local appearance to the scene.

Here is a :47 second render in 3dsmax - using FinalRender.

Although FinalRender is not doing much here. There are no tweaks done to any textures yet.. just some spec adjustment... but otherwise its the default scene... no textures.

Just playing around with some light. If going this route in the shadows this much.. I would probably go scanline.. and get a 20 second render or less. Comped in Combustion.

FeD - I hope your "forest" can be a photo taken locally and comped in, so it doesn't take forever to render?

jmBoekestein - Keep going with those tests. If you setting on a back-lit image with the sun behind, try some rim light and glints from the sun on the train.

Labad85 - Not late at all, right in the middle. Once you get the sky in there it'll be easier to tell if the lighting matches. Don't forget the "local" part of the challenge, to make it look like Poland. The motion blur looks good, it'll get better when there are highlights and variation on the train. Don't use motion blur in all your test renders because it's too slow, though, so turn it off until you get nice shading, lighting, and integration with the local environment.

snoopyBG - With motion blur in real photographs and film frames, there's no way to tell which way something is moving along its path. If something's moving at a constant speed while the shutter is opened, and the lighting is uniform while the shutter is opened, then the blur is uniform. For example, if you took pictures of an apple sometimes falling downwards, and sometimes being tossed upwards in front of the camera, you couldn't tell them apart after you took them because the motion blur would be the same.

mmoses00 - Beutiful film noir image! I love it! For the "local" angle, I think there's room for a distinctive city skyline in sillouhette in the background, or something distinctive to San Francisco like that?

Where are the people? This is a 2 min render in Finalrender/3dsmax. I used just a full beauty pass and a ZDepth pass to do some soft effects and fog in Combustion. It could definitely be better in regard to light direction...and composition... and some people milling around and sitting would be nice as well. This set is some leftover gamelevel stuff I had laying around.... and the foreground textures are pretty lowres. But it feels kinda cool. Pretty paint job on this train!

Hello everyone.

Jeremy : I am half way on making the changes you mentioned (nothing to post yet), as well as adding the final elements on the scene, so I thought I'd share one more small update.
Leaves are paint effects, rendered with Maya software - comped in Photoshop.

http://i264.photobucket.com/albums/ii181/leoni_kou/Train%20cgsociety/UpdateLeavesTestVingete.jpg

I hope it doesn't look very bad with the leaves, coz I kind of like them.

The weather is getting really nice these days in Greece, that it is so hard to get to work! :D




mmoses00 - I like your first render! Very cinematic indeed. If you introduced something yellow, it would be like a scene from sin city! Haha! Good one!

Labad85 - Cool Motion Blur and nice Camera!

Hello Jeremy and everyone!

I didn't know CGTalk but when I saw the images posted for this challenge I decided to join!

Below there's my first image just for giving the general mood (the darkest areas is too dark).
The background is a photo of the lake surrounding my town with digital painted clouds then used for IBL. I cleaned up the geometry from .obj files and did a new UV Layout in Maya, painted the Color, Bump and Specular Textures in Photoshop, quick rendered in Mental Ray and Post-Processed the Image in Photoshop again. Now I'm working on other objects, Train Textures, Shaders and a more complex Light setup (now there's only a Direct light, IBL and an AO Pass).

Leonikou - Beautiful upgrade! I love the colors and feel. Glad you're still working on making the sea more visible, maybe getting rid of water tower or pushing it back in space so it appears smaller would help. The DOF looks very fake, with such a harsh transition between blurred and unblurred leaves.

mmoses00 - Good start, the building fits well with the train. Maybe you could take pictures of storefronts in the Ferry Terminal building and map those along the side walls. Light seems to leak through under the corner in the foreground, maybe you need some occlusion or at least better defined shadows. The reflections on the side of the train look like pure black and white areas, maybe it just needs to be given something else to reflect.

Slight hint of Bay Bridge back there. Just did not have time to model up a sea lion, but a sea lion should be in there. Yes, looks too new to be down there..Again... not too keen on texturing everything.. just playing with light. This is rendered in 3dsmax scanline - basic render with two lights.. and a couple of caustic gobos for the light caustics. Just for quick run and gun lighting, this is a single beauty pass, which renders almost like what you see here, and a Zdepth pass, used in comp for murkyness. This scene can easily be animated, as the water is just noise and wave spacewarp controlled in max. Fish are a particle system. Render time = 49 sec for 1280x720 Comped in Combustion.

mmoses00 - Terrific! It looks like you have nailed the underwater challenge as well.

Feanor77 - Welcome! That's a great scene, nice colors, good integration with the backdrop. The fill lighting is uneven, with fill on the train and water tower, but none on other surfaces. Even if it's all coming from an IBL sphere, differences like the reflectivity of different shaders can still make the amount of fill light look inconsistent.

Don't mess with the train engineer! -- Cue Wilhelm Scream (http://www.youtube.com/watch?v=cdbYsoEasio) on that guy on the left.

This is 3dsmax and FinalRender. 1 min render.. a single sun omni and a few attenuated fill omnis + the GI skylight and a sky dome to reflect into the train. In my experience comparing Mental ray, Brazil, VRAY and FinalRender, FR has always blown the doors off the others in speed for getting pretty renders. Composited in Combustion. Dust effects added using Particle Illusion realtime particles! This took 4 hrs from start to finish. The guys and horses are leftover assets I had laying around.... so layout, lighting, and comping took up the 4 hours.

This particular model is supposed to be a diesel locomotive, this model in particular began the transition from steam to Diesel power in the USA, although in this contest the train and the scene look should be adapted to everyone's country.

I say that because this scene could be a good excuse to test some smoke, in case the train is moving. Stacks are more or less modelled in the roof of locomotive. Again, in railpictures.net you will find references about what smoke from diesel locomotives should look like.

In many photographs smoke does not show up or it is just heat, I think it depends on the weather or and the particular condition of the locomotive. Anyway I think It could be a good addition to our renders.

this is another iteration of my work, I've tried to incorporate all your suggestions, sometimes with little fortune (shack glass). In the next render I will try to do what you suggested about making the more distant things fade into the distance through the air and dust. I'll add some smoke too.

In this render I've used path tracing + HDRI + sunlight + frontal fill ligh

Hello Jeremy,

I finally had some time to work on this so here it is. Even thought I am from San Francisco this version of the train was inspired by some images that I saw online. It's work in progress however, I wanted to submit what I have so far. The big image is the final comp. From left to right, Key light layer, Ambient occlusion layer and diffuse layer.

Even though procedural texturing it's never my choice, I end up texturing the floor, fence and other elements procedurally because there were too many of them. I couldn't really deal with transferring uvs, and all of that however, the major elements were properly unwrapped and textured using photographs.

As far as lighting goes I have a directional light coming from the right hand side for the key light layer. I have also set up an array of spot lights for the diffuse layer and I also have the occlusion layer.

Let me know what you think Jeremy and if anybody else has a positive comment or suggestion please feel free to do so.
Cheers,

this is a light blender version of the scene. All subdivision surf. modifiers and the ballast stones have been removed.

http://www.megaupload.com/?d=Y282Z0VI

If your software does not support subdivision surfaces, then apply subsurf before exporting. I think only the locomotive main mesh need subsurf and maybe some other locomotive parts (doors and round windows frames). Send me a private missage if you need help about how to apply subsurf in Blender, anyway here there is some info.

Maya users should use "objects groups" option in the OBJ export panel to get separated meshes.

Hi everyone

This is my quick lighting setup using MR Physical sun and sky. I kinda like the result, but got some problems too

It seems I can;t change the shadow color, or disable the shadow for further compositing.
Is it because it's suppose to be "Physical" correct,so there is no need to modifiy the shadow color? or there is something else I should know about...

I've googled the problem but nothing useful. I am hoping that I can get the answer here~

m96 - Thanks a lot man! Are you into 3D as well?


emfj25 - Great start Elke, that is a nice image! I think that the front window panels are going too bright at the moment.


samo - Hey, it is coming along pretty nice. I like the way the top of the rails is reflecting, but I think that the image might be a little overexposed (white burnt) on the left side. Maybe try colouring the Key Lighting ( Sun ) . I actually almost never leave my lights completely white.

Martin Romero - Nice start! I like rusty textures. I know it is a wip image but it would feel nicer if you made some nice decalls and signs on the train, so that it looks local! Also although there is an occlusion pass, it is barely noticable in the final comp. (might have to do with the blending modes?) keep it up. :thumbsup:

Visua - Great grass man!

mirmel - Wow. That is a nice composition, and I think it can become a great piece! It sets you off to a nice mood, and the way the background fades off to the fog is very good!
I think that the front needs more fill light (like the fill on the train on the right)
and the textures on the ground needs more detail, especially if you want a dessert environment (cracks, sand etc.). Because of the dramatic sun position, it would be nice to see all the shadow work on the ground (which is lost right now) and some more back - rim lighting on the models. (like the back train which looks fantastic with its nice highlight.)
Sorry for all these comments. :)

hueman - Nice camera and composition! I think that the rails might be slightly above the ground, (they seem to float in the render) .The texturing looks nice, but you might need higher resolution textures for the walls on the left and the roof perhaps. Keep it up.

mirmel
03-26-2008, 12:04 PM

yes .. you are right for the rim light, I'll add it!

hueman - Nice scene! It doesn't look distinctly Indian to me yet, maybe it's the lack of people in the shot, but at least making some of the signs more prominant might help provide local flavor. If you're interested in sharpness, check your anti-aliasing settings. Good anti-aliasing with a Mitchell or Lancoz filter helps a lot. I think you have a bit too much fill light, you could have less fill under the awnings and in shadow areas, and make more of the fill a cooler (more blue) color compared to the warmer sun light. The glass train windows and windows on the station could use a brighter, more blue reflection too.

zcyviper - Welcome! That's a good start. See if you can get the sunlight brighter, with less fill light and darker shadows. A little more variety in texture and color will add contrast to the scene as well.

mirmel - Great! I love your scene! Nice composition! I'm not sure everyone would guess right away that it was in Italy, maybe some Italian signs could be added, or text on the trains? There's a thin outlinearound the signal in the center that really should only be a rim on the sun side, not running up both sides. The highlights or reflections running along the top of the rails in the foreground look like they should be blocked underneath the train, maybe you could add some shadows or make sure the train is reflected there?

visua - Nice scene! It looks like the train is about to hit the end of the tracks, though... The grass is looking good, I hope you can texture the rest of the scene as well. Think about whether your background image could include more than just sky, to capture the local look of Sweden.

MartinRomero - Great scene overall! The white patches don't look done yet - if they are intentional to look like snow or something, then try another texture on them. The train is nicely textured on the metal, I think the windows and front headlight will need the same level of attention. The telephone pole could use a tiny bit more fill light, just to make sure it gets enough bounce from the white lower down and fill from the sky higher up. There's too much fill in the shadow of the train, though, that area needs more shadows or occlusion for the amount of light there. The base of the signal to the left of the train doesn't look well connected to the ground, more shadows or occlusion are needed there. A little fog or depth fading could help make the far horizon shift in color more with distance.

mmoses00 - All wonderful images. Thanks for the re-cap!

Samo - From your image back on 3/20, it looks terrific! The sunlight is very frontal, and I wonder if moving it off to the side more would make things look less flat and give better shaping to round surfaces like the train and telephone pole. The bottom of the plants should be similar tone to the ground under the plants, so if the bottom of the plants is going black then the shadow should be darker. The end of the train seems to connect with the round silos in the background, as if they were being pulled by the last car, maybe you could shift that around to avoid that tangency. A little more depth fading to simulate atmosphere or dust would help with the sense of distance in the scene, so if the blacks don't go quite as black in the background that'll be more realistic.

lighthunder - Looking good! Keep going with texturing the buildings.

mirmel - Great! I love your scene! Nice composition! I'm not sure everyone would guess right away that it was in Italy, maybe some Italian signs could be added, or text on the trains? There's a thin outlinearound the signal in the center that really should only be a rim on the sun side, not running up both sides. The highlights or reflections running along the top of the rails in the foreground look like they should be blocked underneath the train, maybe you could add some shadows or make sure the train is reflected there?


Thank you so much Jeremy to spending your spare time helping us!!!
I'll follow every advices you told me :)!
The reflections along the top of the rails are created by an env ball map, I'll try to block them under the foreground train with a map..

bye!

Hello Jeremy,


Hey, thanks a lot for your comments. I am currently working on some chenges to the scene. I don't really know what happen with the occlusion. I multiplied it the way I should but still didn't show up properly. I will post the new version as soon as I can. I know I am running out of time. Anyways, thank you so much I am glad I was able to participate on this one.

Hi!! every body


*Marco I like your scene, I think that looks great, I see that you put the typical mountains from Costa Rica very nice :thumbsup:… the only thing is that for me the Sign is to clean for the overall of the scene.

Your idea of putting rain is very cool and the fog is going to help you with the atmosphere, try it, I thing is going to look great. Suerte :)



* Samo I really like your scene, I like the colors… I love the background with the mountains:), maybe for me the grass is too green, I thing the dust will give you more atmosphere but it looks very nice, and your black and white scene… wow! ¡Me gusta mucho!

Hi everyone

just a quick update, as you can see I decided to drop the cast day setting in favor of a night scene, I'll try to add a few details tomorrow but since I need to go to a seminar first I honestly don't know if I'm gonna get much done this weekend. Render time right now is 4 minutes and 23 seconds.http://teq.3dwars.net/test8-night.jpg

emfj25 - Nice image #142, I really like it. The wall is well integrated. The front windows and front headlight of the train could both go to an value in-between the darkness of the headlight and the brightness of the windows. The window of the little building is too bright also. Maybe a little dust being kicked-up could add to the scene.

hueman - Looking good. Maybe the front windows don't need to be transparent at all, and could use some dust or dirt. The lower right cubes look over-lit, as if there's no shadowing or occlusion between them, and could be better textured. Maybe the wheels of the train cars could be a different color than the side to give variety. The scene could use some dust or atmosphere to make the more distant parts look further back. The soft shadow on the wall need more shadow rays (more samples) so it doesn't look grainy.

teq - Good start on the night scene. Maybe parts of the train could be darker and fall into shadow, and there could be more artificial lights i nthe scene. The white thing in the center left looks too bright now, but a sodium lamp above it might motivate it. You can use different colors for the different types of lights if you want.

CBMarco - Welcome! That's terrific! Really great image. The train's front windows don't need to be transparent, they could just reflect or be dirty. The light on the side wheels of the train on the left doesn't look convincing, maybe the wheels could go less white and if it's supposed to be light from the house there then you could have some hit the side of the train. The lit area in the center forground could fade out with distance, and maybe the plants could get more translucently lit if there's that much light there.

Hi everyone and thanks to Jeremy for feedback!

I saw a lot of wonderful works so the challenge is very exciting for me:

tuffmutt1: the night scene is stunning and I like the color palette.

FeD: very evocative lighting!

Leonikou: great texturing and shading job specially the procedural rust and the glass!

mmoses00: the "Train Reef" is magic but maybe the train is too clean, with some "underwater aging" would be perfect...

And now...
This is my final version (I hope) in color and Black & White. The color version is quite illustrative and based on color contrast more than on realism. I decided to work on a B&W version too because without color the shading and lighting are better focused, after all this is a lighting challenge and at last I prefer this one.

The original images are at 4K resolution but I posted at 1280x720 and you can find an HD Version Here (http://www.claudiolissi.it/CGTalk/localTrain_Lake_1080.jpg)and HD B&W Version Here (http://www.claudiolissi.it/CGTalk/localTrain_Lake_BW_1080.jpg)

davidac86: I like your artwork, the "dawn / early morning" light balance of scene is really nice and the grass is wonderful, but two "critiques":
1) The bump mapping on train is too strong I think. Looking at wires on right side of images maybe the bump is stressed by the post-process sharpening filter (Photoshop Unsharp Mask with no threshold or too wide radius).
2) The foreground wood have color texture perpendicular to bump and stretched UV and too low resolution textures; you can adjust only the first 3/4 pieces, the distance fade the problem with the others.

Good challenge!

The goods cars in the background needs rails I think. Also that vertical post you have in the foreground is suposed to be a milepost rather than a signal post. A signal post should be higher, and many times semaphor posts are used to place them.

The semaphor could be a good place to place a small light, if the train is before the semaphor light, then the light could be green, if the train just passed the semaphor, the semaphor arm should be lowered in red position and the light should be red. Google "railway arm semaphor" and you will get an idea how these semaphors worked.

The headlamp in the locomotive is maybe too bright. Use some numbers in the locomotive, locomotive have always numbers to differenciate them.

The shack glasses can use some dirt, you know, windows glasses get always dirt near the edges.

The goods cars seem to be stationary in a railway yard, I will place some distant lighting simulating that the railway yard is iluminated.

Thanks for the advices, the goods cars in tha background are supposed to be abandoned so i guess i'll leave them like that for the moment , about the semaphor i think it would be red light then ,change the signal to amile post, put the numbers on the train and lower the headlamp light and put dirt on the windows...the only problem is i dont have the scene file with me , just the psd , so ill try to work it all out in photoshop :scream: but i thibk it can be done , well anyway thx for the good critiques... :thumbsup:

Hi All,

Wanted to give the challenge a try I've always liked these old f-unit trains. I based my paint scheme on the old Santa Fe "Warbonnet". The local station here in Orange, CA is a remodel of the Santa Fe Depot that has been here since the turn of last century. I thought it would be cool for one of the trains from the 40's to make it back to the station.

I spent a lot of time creating the textures for the engines and have not had enough time to pay all the attention I'd have liked to texturing the other parts.

Thanks for the challenge and thak you Alvaro for sharing such a cool model.

I see that you have removed the lower frontal section of the locomotive. If there is an element that is common in most locomotives is that, because it helps to remove obstacles and snow off the rails as the train goes. Also as I recommended to CBMarco, those arm semaphors are a good excuse to place small green, yellow or red trafic lights.

RErender and franciscorq

Nice renders. Only two minor details, the horns in the roof and the roof ifself gets very very dirty because usually nobody cleans that part, so It would make them dirtier. The coupler should be bare oxidated iron. Because of security, in real life is forbiden to paint couplers because is bad to detect deterioration and cracks in them.

I like it; it looks like San Jose... very nice :). But the little wood house it bothers me a little bit, for me is out of place. And maybe increase the bump in some places, to feel the texture a little more
In some places of the train the texture look pull out or starchy (I don’t know how to say it in English) *La textura se ve un poquito estirada en uno de los lados del tren.*:D

But it looks real nice, the buildings and the mountains… very nice. very San Jose:thumbsup:

Very nice overall image! :thumbsup:
I like specially the gobo shadows on the left and the diagonal line composition.
Maybe the shading on train is too far away the metallic behaviour, there is a lot of dust (great texturing) but some metallic "spot" on cleaner parts would be better I think!

Skamierski - What are you talking about? I think the desease must have influenced your judgement. :eek:


krizstof - I think you have a great feeling in your image. The texturing is very nice, especially in the tunel area and most of the train. There is a great rich environmet created by the vegetation, the dust ,and the nice lighting (gobos rule!) .

The glass parts of the render need more work. The shack is brilliant but the window glass is way reflective. Also the windows on the train should reflect the lighting better. (there is a wide eccentricity and it makes them feel like strange plastic where the sun hits them.)

Very nice scene, the dust and the vegetation really brings it to life.! :thumbsup:

I'd agree that bump on the right wall ruined a great image for me...

there's also some texture streching on the front of the train (or is it just me??)

Feanor77 - Great image! I think the fill levels are maybe just a little too low on the telephone pole, compared to the other signals and back-lit objects. The side of the train looks as if it is reflective, but reflecting something big and red instead of the objects next to it? Maybe you could knock that red down a bit, especially on the back car?

davidac86 - Great work! I think the bump maps are too deep on the train, it looks very embossed. The train's front windows don't need to be very transparent, just darkness and reflections would make sense there. I love the vegetation, that's really convincing. The texture on the foreground train tracks could use some work, especially the wood texture on the rails themselves.

CBMarco - Terrific final entry! I love it.

mirmel - Great work! I love your final image.

teq - Great work! Everything looks very clear, if there's something else I might do to that image it would be to add some fog or depth-fading or glows around some of the light sources.

RErender - I love it! You've really nailed the integration. If there would any tweaks, I'd say the front windows of the train could use more of the blue reflection that you see in the number 49 panels, and the train could use a little more texture in and around the front headlights. Those horns on top could be reflective metal, too.

franciscorq - Terrific scene! If there were some tweaks, I'd say the front windows could be more reflective and less transparent. The center of the side seems to have a bright gray panel, and then mostly darkness underneath that, it would be nice to tone down that panel a bit but see alittle more of what's underneath it. The screen-right area could use a background layer with more rows of corn.

emfj25 - Great work! The color ones are definately the strongest.

Skamierski - Nice work! Maybe when you feel better you could find something to make it look more distinctly German, in terms of buildings, signs, backgrounds, text on the train, etc.? The train almost has some of the colors of the German flag already.

wakart - nice work! I think the impression of having the sun low in the background could be improved with some rim light comign from the back, and fill light trowing yellow onto the train (the back of the train would get more of the yellow light, not the front) and rims or kicks on the things in the left and maybe some atmosphere so it got more hazy with distance as you went back into the yellow light. The background tanks on the right could use more tesselation so they look smoother and rounder.

krizstof - Nice job! The grass and fence on the right are very believable. I think the telephone pole and the scaffolding on the hill and a few other things need a little blue fill light from the sky. The window of the little house looks very bright, I can't tell if it's supposed to be a reflection or a bright light inside, but you could tone that down so it looks like dark glass with a little reflection.

digitalframes - Good start! It could use some texturing of course. I don't know where all the brightness is coming from on that train rail, a reflection of the sky should get blocked as you go under the train. The impression of the sun setting in the background could give you a lot of kick and rim lighting on the buildings and poles and train, that could look great.

Samo - Wonderful image.

Thank you! I'll add some post effects later. I already tried a few things like dust and fog as well as zdepth, but I always ended up exchanging the local look with more atmosphere which wasn't what I wanted then again I didn't have much time to fiddle around with the settings.

Thanks Jeremy! You're right with all critiques. I love this kind of feedback, is a great way to learn. I always preferred the "Black and White" version of my work and now you exlplained me why! When I graded the image for color contrasts I boosted the reds and in the B&W this is not visible!

jbrckovic - Welcome. Too early to comment.

ShamKiR - Nice image! I think the directionality of the light could be better defined, with more light from the side. You have the highlight from the sun in the upper right, but the illumination and shadows look like they are coming straight-down, not from the right. Maybe the pole on the right could get rim-lit by the sun. You have could also get some darker tones in the shadowed areas, like the inside of the right rail of the track.

Visua: I've got the same issues but only in viewports visualization. You can resolve with double face rendering (easy solution but longer rendertime) or (more efficent solution but time consuming) with conform, clean up and/or manually reversing the flipped normals. I found the .obj files cleaner but with maya file and .objs I remade some UV layout because they were very confused too.

Feanor77 - Winners and galleries will be on-line soon. I fell far behind on doing those when I was working on wall-e, but that's done now and I'll soon have things on-line.

chickenkts - Beautiful Image! I love it! In terms of feedback, the light from the headlight doesn't look as realistic as it could, especially the little lines drawn out from the center. And I don't really get the impression of that being "local" in Vietnam, nothing seems really Vietnamese about the background or the train.

Anuradha - Nice job. I don't think the Maya Software Renderer is any faster than Mental Ray, maybe your render settings just weren't optimized. The DOF seems really fake, especially in the foreground, you could try getting rid of that and just adding a little more haze to the background. I'd expect to see more clearly defined shadows of the tracks.

Nice render But İ think there is too much bump on some shaders

godzik -

Good start on the scene. It needs reflections of the sky and surrounding environment in the glass windows on the front of the train, the metal rails of the tracks, and any other reflective parts. Right now there seems to be a lot of blue fill light from the sky in some areas, like to the right of the train, but none in other areas, like the shadow to the left of the train, or the rails of the tracks. Try to figure out what your fill light looks like without any sun and even that out.
