IMPORTANT EDIT: THIS IS AN OLD CHALLENGE. Please enjoy reading through this thread as an archive, but it is closed to new posts. If you scroll down to the Challenge #1 section of the download page, you can still download the 3D files, and also can view a gallery of top entries.


Here is the link to the first scene-
http://www.3drender.com/challenges/

There are two versions, an OBJ and MB. As stated before, no textures with this model, so some work will involved in the shading. Although shading is obviously important, the main study of this exercise is the lighting. This is a very open challenge, so any app and lighting technique such as GI etc, is fine to use. If there are enough entries, then maybe we could split into GI and non GI entries, but for now we will keep everything together. Also, there will be no set time deadline to start with, we will give it a couple of weeks and see what sort of response we get. For future challenges we may have locked off views, but for this one, any composition is fine.

There is no set submission requirement yet, but I think for now, a final image, a shot of your lighting rig setup, and maybe a brief description of your methods and the result/mood you were trying to achieve would be good.

Happy illuminating!

Dan W.

Ok no texutres ..but can we assign procedural material and shade the objects with different types of shading. or only one white material as clay?

Dan Wade
01-12-2006, 12:38 PM
Yea jigu. You can do any mapping you want. Painted or any other method. Like i said before, this is a very open challenge, i would have painted some up myself, but i didnt really have enough time. Actualy some black and white entires would be nice too! lol

just one question: what about the perspective?.. are we allowed to place the camera where we want to?

Dan Wade
01-12-2006, 03:51 PM
Yes, you can have any composition you want. Future challenges may have locked off views, but this is open.

Glad the scene is working ok for you guys. Some of the geomtry could be a little lighter i guess. Some of the objects could do with maybe a sub-division or two at rendertime. And sorry to those having to lay out UVs too!

Hi Dan!

I post the result into this post or in the Lighting Challenges sub-room in a new post? :)

jeremybirn
01-12-2006, 06:24 PM
I don't think any new threads are needed yet. You can just post your renders here.

This forum will eventually have threads for a lot of different challenges, so if we can keep all the fruit bowl posts in the same thread, then in a few years (and many challenges from now) people will be glad if they can look through the whole thing in one place.

This forum will eventually have a thread about rules and conduct, which will be open for discussion. But right now we want to see what everyone does without imposing a lot of rules. If someone uses a toon renderer and someone else does global illumination, we'll just look at all the results. As Dan said, the one expectation we have is that you discuss what tools, techniques, and set-up you used, because other artists are interested in seeing how you do your work.

This forum will eventually have a thread about ideas for future challenges, but right now, there are already some other scenes ready to go, and we really want to see what people do with the first challenge before we plan too many others.

Just for fun, couple of quick tests. Nothing fancy, spots, omnis, some procedural textures for fruits, and some postpoduction (mostly color correction and texture overlays). Not final by any means, i'll probably start over few more times. Hopefully i'll came up with something more original ;)

this was actually rendered in b/w-color style ;)

azazel -

That's terrific! It's great to see our challenges off to such a great start. Your work looks very painterly. Maybe one banana looks as if it had a coat of varnish on it. And grapes - grapes have a sort of "dusty" quality to them. Buy some grapes, study them at different tempertures, hold them, eat them, I hope you see what I mean. It's not dust, it's more like wetness on a skin that scatters light, but please tell me I'm not crazy, there's something that looks sortof dusty about grapes, isn't there? The bowl is looking good, maybe the reflection of the foreground cherry and banana stem is warped strangely, but that's probably just how raytraced reflections are looking. Other people will tell me if my comments are appropriate or too fussy or anything, overall it's great that you have a first render looking this good.

-jeremy

01-12-2006, 09:08 PM
Azazel,

That is really nice! I love the painterly quality you gave it. The banana on the far left looks great too. I think the one next to it could use less specular but the image is great for a "quick test". :)

azazel
01-12-2006, 09:57 PM
Thanks, guys. Much appreciated.I know about the grapes, i'll work on that for sure for final version. Also, these violet thingies behind the apple are probably peaches, and it could be fun to make proper 'peachy' shader for them, instead of 'random' one as it is now ;).

The painterly effect, apart of the light setup, is probably due to some simple photoshop work - maybe i should post the psd file, it'd be easier than writing it ;)

is there a deadline for entry for this challenge?

MooseDog
01-12-2006, 10:40 PM
W.I.P.

Lighting set-up:

a big area light up and to the left, with a linear fall-off;
a small area light down and to the right, with an inverse squared fall-off and no shadow casting;
a specular-only point light up and to the right;
no GI.

Procedural textures, tools are Lightwave and Photoshop.


Hope this thing takes off, it's a great idea!

jeremybirn
01-12-2006, 11:04 PM

There's no deadline. But, there will be another challenge started every 2 or 3 weeks. More people will be looking at this thread over the next two weeks than will ever be looking at it again, so if you want your work to be noticed and commented upon, getting something posted in the next two weeks would seem like a good idea.

MooseDog -

Hard to tell much from early tests, but it looks like the final will need more shadows or occlusion added. The test seems to have too much light that lacks shadows or occlusion.

Maya 6 should be able to import the .obj file. I think you have to activate an obj import plug-in before you can import it.

If that fails someone could convert the Maya file to .ma for you (you can edit an .ma file to remove the "requires maya 7" line) but please try the .obj.

Hey all!
I just downloaded the obj, works perfect with max 7, the details are amazing! I especially love the smoothness of the cloth :) I'll get to work on this once I get my scanner working.

Also, many thanks to Dan and Jeremy for setting this up.

Ta!

Good start. The shaping of how light wraps around a grape is a little hard to capture, but see what you can do to make the grapes look translucent. Overall the lighting is looking very "sourcy" - as if it were sitting between two lightbulbs. Some of the shadows, like the cherry stem shadow on the left side of the orange (if that's what that is), just don't seem to be motivated by anything natural. If you're going to work on the shaders or textures, do that before you do more lighting, some of the lighting problems like the end of the banana going so bright might just get fixed by a map.

-jeremy

Angel: These rims look really good. Any plans for some colored lights ?

Jason, I like the blueish light from above, works very nice on grapes. I'm not sure if i like the almost central composition, and cropping seems bit too tight.

ACamacho
01-13-2006, 11:46 AM
Azazel,

I plan on adding color to the lights. I'm just waiting till I get started on texturing before I do that.

otacon
01-13-2006, 01:12 PM
Thanks azazel. Your right, composition is not so good.

ACamacho, looking nice. I would also like to see it with some color.

01-13-2006, 01:54 PM
Great work so far (everyone)! I've never had to render "artsy" scenes like this so I'd like to learn. It would be great if you guys could post some tips on light placement. Or if there are any related links maybe we can take a que from the f/x challenges and create a resource thread that has links to helpful resources. :shrug:

Anyway, I'll attach my attempt (3dsmax). 4 lights (1 spot and 3 omni's)...with some color correcting in photoshop (and too much DOF). Thanks in advance for any critiques & tips/tricks.

Otacon -

Great work! That orange looks amazing! Besides the orange, the grapes are well defined, the fabric on the right side is nicely shaped. If you focus on the right side of the frame, your "first go" could be final. Some of the other fruit I'm sure you'll agree could use another pass, maybe the pear and apple need to reflect something or be given broader highlights that look like a reflection. It seems as if there's a light adding highlights onto the lower, darker grapes that should be shadowing but isn't, although that could be a rim light down there, there's something going on between the pear body and the grapes.

http://www.angelcamacho-torres.com/files/fruit_unshaded.jpg

Looking good, nice balance between dark and light. Those highlights on the pear, especially the one at the middle "waistline" area makes the pear look CG. I wonder about the lighting on the backdrop, and the composition - everything keeps leading my eye towards the right side of the frame, and nothing draws me back to the left. Maybe putting some of the highlights and contrast that's on the right side of the backdrop onto the left side of the backdrop could make some contrast there. And maybe the image needs to be more widescreen or something as well?

Effort #2. Changed the set-up: smaller area light for the key, same for the fill, added a negative value for a clone of the fill, removed all fall-offs, left the spec-only as it was. A little fiddling in Photoshop and we have:

Is it Light grey, shader adjustment, then +textures?

Great work and a great challenge thread.

AN idea for the next challenge could be replicate the lighting in this photo. :)

Sorry people, for the time being, the challenge is suspended. The original model was from a free source, but we need offical permission from the website to use it. Im gonna remodel those elements as soon as poss, then post it up again, or see if i can sort out permission. Really sorry, will sort things out as soon as poss.

Hay people. Sorry, think i went abit far with suspending things. Just sorting some stuff out and will have the scene back up very soon. In the meantime, the original un-edited model is freely available over at 3dcafe.com, so if people want to use that, then that should be fine. For those who have my model, please continue working, just be aware that the bannana, apple and grapes are from 3dcafe.com. Those elements were not that great anyway, so Jeremy has kindly offered to remodel them.

Again, really sorry, will have the main scene up as soon as poss. In the meantime, please enjoy the current entries.

Thanks Jeremy for the comments. Maybe I'll try shifting the keyLight over more to the left. But also I am gonna play with the colors of the fruit to bring your eye back the the left. Can't do much till after work though hehe.

Keep up the good work guys!

Original post:

Nice ones everyone :)

This one was done in Blender 2.40, internal renderer, using procedural shaders plus vertex colors and ambient occlusion. Two lamps were used (one area light, one omnidirectional lamp).

Here's my first render of the light setup. No textures and still a bit noisy...

I'm goint for a early morning (breakfast) mood.

One area light as the main/sun and a point to lighten up a bit.
GI with a dark gray backdrop to illuminate the room.
Also used a enviroment map (LL) to create the reflections. I'm not happy with the reflections at the current state, but it will be sorted out for the final render.

Trying out a few ways, but this is one 'effort' :) Shading is still temporary on the bananas especially

http://i20.photobucket.com/albums/b210/QBod/Fruit1.jpg

EDIT: I should explain a little about it I guess.

There are 3 lights in the scene, 1 point light for the rim effect (i could use shaders for that but as this is a lighting challenge ;)) and 2 spotlights. One for fill and one with a gobo to create the shadowed lines.

Rendered with PRman in jus over 3 mins, and no raytracing used yet. I wanted to see how i can get on without using tracing features.

No post work, straight from the camera.

Now I have got bored with the banana shader, i am going back to work on the lighting. :)

Had time this morning to do some tweaking and render at higher samples. Some negative lamps were introduced in back to further sculpt contrasting to complement the revised ambient occlusion settings.

:thumbsup: This is my favorite so far! Lovely. A touch more detail on the apple leaf and banana stem is the only thing I would want as far as texturing goes. Maybe just a touch more light around the bowl. Not too much though, it would spoil the drama.

Some quick tinkering, all procedural, all mental ray with a minor glare done in post.

Naturally, SSS on the grapes.... ;) :D :eek: :twisted:

I wasn't going for some kind of "mood", I was more going for "someone puts bowl of fruit on blanket and takes a picture" look.

Several things need some texturing (i.e. teh bananas ends, e.t.c.)

Hello! This is pretty cool. I have one question: Am I allowed to use a texture for the background? You arn't going to be able to see it. I need it because in Blender and YafRay, you need a texture for the background. Like a sky.

Thanks ziljidian, I'll google for a .rar utility then. Hopefully I'll post my scene this week (I still have to learn Blender). Coming from Maya. . . blender is not very intuitive. But it's free, and I can put up with a lot for that.

Let me guess: you play drums, right? ;)

Take this with a shaker of salt, as I am not very good yet, but your banana has some blown-out highlights while the orange is just barely lit. Maybe you could decrease the intensity of the banana-light and put another one on the orange?

Hi guys,
Plz tell me the link where i can get this mesh file for maya.I too wann to join u guys

thanks
raghu

I have the files back up. Hope they are working. They are version 2 files now:

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

By the way, the version 2 files replace some fruit items that had been downloaded from a free model site (3dcafe.com) with new, original models. There are _no_ legal problems for any artist to use the first models in their rendering, you can stick with what was up the first time. We just saw fine print in that site's licence agreement that the models themselves shouldn't be given away for free by another website, so they needed to be replaced in the version of the scene that will be given away in the lighting challenge archives.

The version 2 scene looks alot like the v1, I positioned all the new fruit very close to where the old fruit was. The Maya file got smaller because I built most of the new models out of NURBS, but to export as .obj they are still converted into polygons in the OBJ version. Maya version requires Maya 7, download the OBJ to import into earlier versions of Maya.

Looks good. Maybe the top banana shouldn't go that white - unless you really want to sell me on it, add an equally bright rim on the plate, make it really look glowing over there - but I like that you are shaping everything as if there were a window to the left of the scene.

The canvas colors, with the gray/blue canvas then the warm/brown canvas on the right side, they somehow look like 2 colors of cloth, instead of colored lights. The cloth in the left foreground is great, though, maybe just less blue on it would help in places.

The "sphere fruit" in back looks like they could use a touch of soft bounce light, being so close to the brightly lit apple and such. For rim light, maybe there could be a touch of rim light on the left side of the spheres, since they are near the light and might be fuzzy peaches by their color. The cherries that are sitting right in front of the grapes, though, that rim light looks a little too bright.

Nice! I wish the plate of fruit and the background were more "connected" somehow. Maybe a shadow or occlusion, unless you want to go the other way and consider the red cloth a lightsource and have it light the plate a little. It would help alot if you had the refractive fruit pick up more of the red, that would definately sell the integration better; just wrapping a red material all the way around the scene might help that.

Evening! :)

Here's how i did it using Maxwell beta 1.2.2a and the C4D connection plugin. Now it's still rendering so this is a wip from meanwhile it's rendering, i know the noise is still quite strong in it but that's the way things are at the moment.

There are two main big light emitting planes in this on each side of the fruitbowl, and one smaller more focused light directed towards the center of the bowl from a top front direction. And last but not least there's also a Skydome to provide with some background slightly yellowish ambient light in the scene.

It been rendering so far for 25 hours 22 minutes 13 seconds on my P4 3ghz 1GB ram puter. It reached sampling level 14,18 in that time.

That's great! I love the translucency on the grapes. Maybe the apple's leaf could be made a little more translucent looking as well (might not need sss, maybe just not going to black so quick would do it...) Maybe the bottom of the banana could use a little more bounce, because its above the white plate, and the core of the shading a little darker where it falls off below the bend. Other than that it's great. Which renderer are you using?

Well here's my final...well final for now. Did little bits here and there during my free time. I didn't move my keyLight because I still wanted some focus on the green grapes. But I added some width to the image and added some procdural shaders to it. Tweaked color a bit in Photoshop and added grain. But for the most part it's sw renderer. I might start lighting a different approach to the scene for the next image. Again, any comments welcome. :)

*On a side note: There are some very cool images here! (esp. the glass one).

That's great. Especially with the way you have the background working, it really feels almost like I'm looking at a painting. If you're doing another pass to fix little things like the leaf, those rim lights on the banana and the left side of the orange look like they'd be better if they were brought down alot. Just my .02.

*Yes, lots of great images here. I was mentioning in the other thread (http://forums.cgsociety.org/showthread.php?t=309874), it'll be great if we get some tutorials and breakdowns based on these projects, so we can put the challenge images together into a gallery along with some useful info from some of the people who made them.

hey jeremy.. thanks for having a look at that and commenting.. im really glad you did..

i used cinema 4D's Advanced render.. besides that i use finalrender, vray, MR and maxwell.. but i decided to go with AR because of its mix between flexibility and ease of use - its a boutique one but i like it ;)
but i have to admit, that a lot of the athmosphere and subtle effects were created in photoshop.. ill post a breakdown tomorrow..

again thanks a lot for your comment.. just an hour ago i told my girlfriend, that i wished soo much for a comment of you because lighting, shading and PP are my strenghts and you´re one of the best at that..

No shading, just playing with colored lights in this one. Four spots, two shadow maps. I should get rid of the highlights of the bounce and fill lights, but I thought rendering in layers would be cheating and my light linking plugin isn't finished yet :p

Jeremy you miss nothing :)
I wanted to add some fuzziness to the Monk's cloth using velvet shadings then I tinted that with the warm orange . That's why the lighting doesnt seem correct on it. I fixed a bit of what you suggested tho with some post effects.. I think it's a part of lighting and rendering too.

Hi Samo -

Since you posted a breakdown in the tutorials & breakdowns (http://forums.cgsociety.org/showthread.php?t=309874) thread, and those are such wonderful learning tools, I'll echo those images in breaking down what you've got so far. I guess how you have the lights labelled over there indicates your original intention, even if that isn't how they came out.

http://img366.imageshack.us/img366/3319/render1f0wt.jpg
This one is clearly the key. (It is the main, brightest light in the image, right?) It is a very frontal key, coming almost from the camera angle. This flattens the image, and it casts the shadows almost straight back, like flash photography, the shadow from the banana stem onto the apple drives that home. You can see the shadow of the fruit on the back wall is like a 2D drop shadow just shifted to the right a bit, and this is also why the plate doesn't appear to be shadowing on the cloth. It is also a very low angle for the key, not lighting the core of the plate, which is why you have the strange situation of the middle of the white plate rendering darker than the cloth underneath it. If you made this brighter, and slid it higher and more to the side, it might clear up some problems.

http://img293.imageshack.us/img293/4336/render1r9gw.jpg
This is a nice subtle fill light that adds a little kick to the fruit as well as tinting some of the wrinkles in the backdrop.

You had it labelled as a rim light, though. There are no rims created around anything, and it would have to be much farther back, behind the backdrop, to do that. Usually you position a rim light so it is visible in the camera view while you aim it, or just in the overscan of the camera view, really opposite from the subject being rimmed though.

http://img366.imageshack.us/img366/5873/render1k9qg.jpg
I see you had it labelled as a key, even though it's clearly overpowered by the brightest light. It could almost work as a kick from the right side though, once the real key is adjusted. If you leave it in the same place, you might unlink it from the apple and put another kick onto the apple from farther back. When an angle on a round surface lands just wrong so that the terminator (the line where the lightness ends and goes into darkness) becomes a vertical line instead of a nice curve following the surface, that hurts the modeling on what's supposed to be a round form.

Hope this helps,

-jeremy

Hey, that's great - nice colors, nice composition. The apple leaf with all those highlights is a little distracting, though, they way it matches the spheres behind it so much. You've got a lot of definition, so things like the cherries really pop out at you, which is great. The red with crisp highlights almost grabs too much attention, as if more warm tones could be shared elsewhere - maybe the highlight on the lower orange could be a cherry reflection instead of a grape reflection, or some warmer streaks on the left banana? These are just thoughts.

I think that is not such a " good lighting or Bad Lighting " in any of these artworks.

What I like of these Artwork, is how many different types of lighting situations people can do with the same subjet.

Hey there everybody,

This lighting challenge is a great idea and very inspirational. :) Here is my go at it:

No GI, SSS or textures. I had first intended to texture everything but once I had started playing with procedurals I kind of liked the way it looked and tried to work with that. For the lighting I used a dome of spotlights, another spotlight as key, a cold one as ambient, as well as another warm and a cold one as fill lights. For rim lighting and to add extra highlights I used two hemis only for the grapes and plums.

Matt :)

Jeremy,

THANKS! It's cool that most of what you pointed out were things that I saw after I posted. You are right about the apple leaf, I don't know what I was thinking...haha. I guess too that in the real world, the bright cherries would radiate more light onto the darker hue of the shadow area on the orange. (The cherries would probably be a bit darker too I think.) That much saturation would probably bleed more. I'll definitely give it another pass.

Thanks for taking the time to give your thoughts, I appreciate it.

trying an high key approach.

as the purpose was lighting, no texture (apple and pear got a cloud on diffuse color though), only shading, ramps and AO.

setup is : a coloured Hemi as directional ambient on the left + a spot as key,

a spot as fill on the right, 2 dimmed lamps in front and above.

blender internal renderer.

vir3d, that looks amazing.

I revisited my second render and tried something different, first with that version and then with a different lighting scheme entirely for a second version below. I used the Blender glow plugin in these renders.

For the second "midnight fruit" render I changed the lighting and added a blue overtone via the World ambient lights settings.

I also adjusted materials to work better in the new lighting. The plate color was changed as well. Three new low-distance negative lamps were added to help darken the right edge of the scene.

Here is the scene breakdown.

http://img30.imageshack.us/img30/5278/viewport1ac.jpg


its a bit sloppy but it got the job done. I used 4 low intensity spots pointing down to create the general feel and ambience and also to create very soft shaows. I light linked 2 spots to the drapery to get the lighting i wanted. then i used an ambient emitting volume light set at a very low intensity to lighten the harsh shadows. Render time was about a minute and a half.

Final. Touched up the shadow bias and added a fill light and also turned up the primary light. Re-did some of the colors.

The lighting is designed to enhance the color of the fruit and to simulate gi with shadow coloring. One of the main goals when starting out was to achieve a relevant shadow with the fast scanline render.

Render time: about a minute.

Just a preliminary attempt to get something different. Still needs texturing, and better composition, but I like the "Godfather-like" idea of intentionally obscuring part of the main plate there.

Edit: Used Art of Illusion with one directional lamp, AO, one shadow-casting semi-transparent plane.

Robertt
01-17-2006, 01:12 AM
I tried something else today, going for more of a soft focus and desaturated look. Pure render from Blender 2.40. Softness was achieved through Blender's built in glow sequencer plugin.

For the coloration, aside from tweaking the shaders and lighting again for this version, I used a transparent plane in front of the camera and set it to 100% Filter, which then affects colors of all things it covers (in this case the entire scene).

hi..here's my take on the challenge..the shadows is bugging me..rendered with 2 lights (spotlight and are light) mib_cie_d and physical_light was connected on the spotlight. MentalRay using FG.

i think the physical_light is the one making the odd shadows..

*edit* i'm not really sure if its ok to use both (mib_cie_d and physical_light) on one light..anyway..

Hi,

here my try with cinema 4d and finalrender2.
Image use one arealight, gi, small dof, sss, velvet shader and some deflectors for the
lighting.

Small color adjust in ps.




Here a view from the viewport:


Wow. Very nice image! The lighting is very natural (due to the GI I guess :) ). I have a couple of suggestions. I wish that there could be more of a variation of light on the cloth. Nothing major but maybe slightly darker towards the top. Right now it all blends into a solid block of color. The other suggestion is to maybe add slight color variation to the grapes.

But just nitpicking. :thumbsup:

Wow! You folks are really renderering out some amazing scenes here. Well I have to get in on this one. I did a quick 3 point lighting setup and splashed some materials and procedural textures on the meshes. I rendered a raytraced scene first and copied this scene for two GI render engine scenes. If I have the time I will work on those and post links to them here. My goal is to setup a lighting environment that is similar to an artist or photographers studio.

Hi!

My first attempy. I'll need to fix some things. I used Maya 6.5. No GI. 9 Lights for fill and soft shadows. One key light, one light to background with mask in Color slot. And three lights to control the speculars in the scene. My big problem are the shaders because i'm not worked before with him in Maya, only with lights.

That's great! The fabric looks terrific. The shaders and textures are all looking good, really. I think maybe the black line at the bottom of the screen right facric is distracting, it would be better if the fabric could continue visible down through the curve more. This might just need one more fill light there. The tops of the bananas going black, maybe that could be fixed. I know the pear is all one object, but if you could find a way to make its stem look more like a stem that would be good too. Maybe the front of the orange looks a little flat, not so much like an orange there. I'm sure some of what I list are the same things you are working on, but this is really a great first version.

Your scene is looking good, but I think there's an issue of how much lighting & darkness comes from the shaders&textures vs. how much comes from your lights. Maybe some things are adjusted too dark in the shaders or textures, like the tops of the bananas, and the fruit stems, so the lighting can't really work on them. With the cherries, it's a 3 way balance: how much from the lights, how much from the shaders/textures, and how much from the reflections. It looks like they might need more reflection and bounce light, the way they go black right where they are touching the white plate, but really you want to play with all three. These are the situations where rendering in passes really helps explore what you're looking for, although for a small area like a cherry maybe just a series of re-renders of that region could help nail it.

heres my second version of the lighting challenge..this time i use 4 lights. used some of the techniques you guys used in your scenes.. still used mib-cie_d on the spotlight, then 2 arealights with deflectors. the one 1 spotlight as the rim light (from ACamacho's technique). this is my first time to do render passes. and compositing them. not much done in composting, just adjusted the blending modes in photoshop.

i'd like to hear from you guys..thanks..

*edit* here (http://www.geebodigital.com/cornblog/CG_lightingChallenge/) is some of the stuff how i came with the image. i'd like to know if i did it right with passes. also i had trouble with the compositing the shadow pass. that is whay there really is no shadow pass..the occlusion was the shadow. thanks again!

raghuramp - work on shadows and occlusion under the fruit, like under the cherry.

holle - I see several people's work that some things appear to be floating a bit, other things cutting through the plate. I don't know if this varies with the level of subdivision on the plate, or is just sloppy modeling on my part. You scene is looking good, but that sense of contact between the cherry and the plate may be getting messed up a bit by the fact that some of them are floating?

Hi jeremy,

I work with c4d and have imported the mesh via obj.
The grapes on the left stick in the plate and a piece of
fabric looks though the palte .... Maybe an import error by

Interesting image. When you walk that line between "realishtic" and NPR, it sometimes feels as if it needs a little push in one direction or the other. I wonder how the image would look with some inking lines, like from a toon shader, and a little more processing to make it look like a drawing or collage?

We've had quite a variety of materials here, it reminds me of Max Headroom's bowtie (in case you've never seen the show, in order to make Max look more like CG, his suit and bowtie were always made of different materials. It would be a plastic, metal, anything but cloth.) Anyway, another nice one if I didn't reply a few pages ago.

Thank you jeremy. Your comments are much appreciated. And I know exactly what you mean as soon as you say. The idea for the challenge image was actually to go for realistic clay but probably my skills still need a bit of refinement. I think there are a couple of reasons for the blurring of the lines between reality and fantasy. One, the grape material probably has just a little too much finesse and two, the orange is textured with geometry and so it just tends toward realistic more or less no matter what the material applied is.

The fruit plate seems to lend itself well to the flatening process although my attempt could still use some work. Our toon shader could use some updating too. Kind of fun though.

Thanks. Render time was pretty long--3h25m. It seems that DOF and SSS don't play too well together. :) Without DOF it renders in under 20 minutes. Without SSS but with DOF it renders in about 20 minutes.

Disclaimer: I'm no Jeremy Birn. But here are a few thoughts:

1. Is the light from a stained-glass window? The "rainbow" look is a bit out of the ordinary.

2. You might want to change something about either the pear or the apple leaf--at first glance they seemed to be the same color. On second glance, the apple leaf is greener than the pear--the pear actually looks blueish. Might be the colored lights. . .

I like the concept!

Here's my effort. I was trying to evoke the feeling of natural sunlight illuminating the scene as if through a kitchen window.

Yep. Assume it's offered fruit in some altar in church. Later, the little church goblins that live under the stone tiles can have a feast on it!


2. You might want to change something about either the pear or the apple leaf--at first glance they seemed to be the same color.


Agreed.... it somehow became more evident when I uploaded it so I actually rendered later from a different angle (but that resulted in some other bad effects.... ah... more later)... it hurt the composition of the overall image with the pear/apple collission.... oh well. I'm not an "art" person I guess :argh: :p

just as a test i tried to setup the same lights and the same fruit materials in electric image EIAS, my other (and longtime!) main 3d app.

rendered with GI and soft raytraced shadows. ...and guess what? - the results are stunningly similiar to the ones rendered in lightwave/ fprime! so maybe it's true that's not the tools... the rendertime was about 1 hour on a quad (edit: at a resolution of 3000 x 2250), and the render quality, as always, is superb!

See if you can debug the double-edge on the banana, where it goes from bright yellow to a red stripe, the hard diagonal line on the orange, and why some of the highlights are looking posterized. A little more bounce light up from the bowl onto the fruit would help, maybe more reflection on the fruit, and definately occlusion from the fruit onto the bowl (like below the banana, it should look darker.)

Thank you very much and congratulations for you and Dan put the light in discussion. Much peoples forget how work with the light design is important for any scene. And... Thanks for tips!:thumbsup:

Thank you! Fabric it's simple combination with 2 blin shaders. With the same map in bump and specular color . The map was produced in Photoshop with Custom Shape Tool.

And now more one version. I don't like of apple shader, but can't fix, any idea to help? I try fix the problems said by Jeremy and i added more one light to made the rim light, with a low intensity, also to represent the reflected light by fabric.

I think maybe some are intimidated to critique with you in da house, Jeremy but I'm not shy.

Master Zap: Ya got mood. No question. I agree with dbates about the apple leaf. It's an unfortunate camera angle that lines them up and the similarity in colors makes them blend into one object. Personally, I have trouble understanding the rays behind the cloth. What's going on there? The way they fall on the cloth and the objects is certainly believable, though.

General question: How are you guys texturing the cloth? I didn't see a UV map.

3Dworks: Is that a basketball dimple bump applied on top of the orange? An hour to render on a Quad? With EI?

holle: I love your render. The only thing that detracts is the stretching of the apple texture at the top. That orange looks really good. I kept looking back at your render when surfacing my orange, but it didn't help.

cgpoint: I like the look of your render. The low res artefacts are giving it a textured look like a painting.

I think maybe there should be a separation of GI and non-GI. I think there was a concern earlier that there might not be enough people posting to do that. Doesn't seem to be a problem now.

Jeremy: Ok, I did 2 more tests. I turned shadows on for all the lights and got this:

http://magicanimation.com/tests/render002.jpg

Now I normally work with 0-5% ambient intensity but with the above and earlier image I tried turning it up to 15% to brighten things up. Well since I was testing with more shadows I figured I might as well test with 0% ambient:

http://magicanimation.com/tests/render003.jpg

I'm not sure which I prefer. Hopefully fresh eyes can tell me what works and what doesn't.

btw - this is fun.

yes, definitely fun! :thumbsup:

i know, the bump map is not yet perfect, LOL... but im missing those typical small dark points inside the orange skin in most other's renderings...

i forgot to specify that i rendered all images with a resolution of 3000 x2250 pixels. the EI render took relatively long because of the GI settings and the soft raytraced shadows.

as for your render, beeing picky, i'm missing a bit more of contrast in it. together with a general slightly blue/greenish color shift the rendering appears a bit 'off'. the grapes do have a strange dark 'aura' around them, maybe a gradient put the wrong way? but yes, green grapes are really difficult to texture - i'm still not convinced by my own ones, LOL

Zarathustra - I don't know which I prefer of those two, maybe the 2nd, but both seem to be missing some of the shadows/occlusion you expect in areas like the plate right under the orange; it gets brighter right where you'd expect it to get darker.

-jeremy

Zarathustra
01-19-2006, 03:10 PM
3dworks: Ok, the resolution of the image makes the rendertime more plausible I suppose. You were right about the grapes. I have an incidence angle gradient on the translucency channel that I applied to the diffuse channel. I removed it from the diffuse and applied a slight procedural because even the green grapes have those blotchy, dull patches. I have to admit, the grapes took the longest to surface even though they don't have any image maps. They just kept looking like olives more than grapes, but I didn't want to give up and change them to red.

Jeremy: The orange isn't sitting directly on the plate. I didn't know if we could move anything. Light is getting under it.

I've always thought it's harder to get that in-between light like in a lot of Pre-Raphealite paintings than say a Caravagio chiaroscuro, but then again everyone loves drama. Here's a new render with more contrasts:

for the fun, a quick 2nd take, lower key and more classical lighting. same textures. No AO this time which lacks a bit.

i tend to prefer the first even if it is a bit flatter by design

Hi guys,
I saw a coworker working on this challenge and thought it would be interesting to take a different approach. This is lit in shake using only a z pass and a bent normals pass. I created serveral macros to do diffuse lighting and shadows. Here is my progress so far.

http://www.pwgraham.com/temp/diffuse-collage.jpg

The shadows are a little off because I'm generating them with just a z pass. I want to add specular highlights and try to do texture mapping in shake using a UV's pass.

Hello everyone, many great entrys on this!! Nice idea this lighting challenges:thumbsup:

Here is my try:
I wanted to make a "dense" light scenario, i'm not very happy with apple and the leaf, and the green olives on the botton are also a little greyish, but well, i kinda happy with the way it looks.

Maya & MentalRay, all textures are procedurals, 3 area lights and finalgather enabled. SSS on the fruits.
Defocus and Levels on Photoshop.

Lookin good Markus. Some quick crits on the shading. The cherries and apple are a little too uniform for my tastes (yum cherries). I think both need a bit more of the specular broken-up.

Does fprime equate to a radiosity solution?

hi jason, nice to see you here - ...agreed for the speculars... :)

yes, fprime does a very fast and accurate radiosity (apparently using a variation of MLT).

Hi Matador, thanks.
Maybe I shouldnt speak while Zap is here lol but the shader is packed with Maya since 6.5 I think. It was downloadable for free at Alias.com when it was released and I think it's still there somewhere. Maybe take a look in the misss test thread in Maya Rendering section here in cgtalk.

Nice rendering BTW ... Keep it up.

Hey all. Well, this entry is a little less playful. Calling it After Hours at a Social Club and trying to achieve the atmosphere that you'd perhaps expect to see in a smoke filled room. Hopefully some of the glow that can be experienced at that hour as well.

Light setup consists of only two lamps. One shadow mapped spot with volumetric halo and one shadow mapped spot. [edit - lights have changed. Please see edit 3 below for details.]

I realize there're still short comings but our shader engine won't be updated for a few weeks yet and the rendering engine shortly after. Or something like that. It's casual. Render time for this image was up a bit since the ray tracer was turned on. 5 or 6 minutes or so.

Hope you enjoy.

Here's a capture of the rig.
http://discusions.home.comcast.net/cgt_fruitplate_setup4.jpg

[edit]as soon as it was posted . . . Image had a flash cube look that had to be repaired. Also added a couple of reflection lights to compensate for new shadows. Post that when the render finishes.

[edit2]figured out a better banana material too. Update with the new settings in a minute.

[edit3]fixed some background aberations that didn't make sense. Added a couple more lights.

Light array now consists of one primary spot with volumetric, one fill spot, three area spots and two reflection lights. All the spots are using shadow maps.

Marty_D: be very very careful when using grays like that - the background fading to gray in places looks disturbing, like an artifact.

lazzhar: the last one is nice, but the violet backdrop clashes with everything else. The pear is great :).

Matador: i like the color palette - my main crit would be the hard edges everywhere. Maybe it has to do with over sharpening. I don't think a full DOF effect would fit, but slightly softening some edges wouldn't harm either. Your previous one seemed bit softer - in that aspect it looked bit better.

Zarathustra
01-20-2006, 05:44 PM
Marty_D: I think it would be better if you framed the shot so that you either saw none of the grey bg wall or more of it. I like the atmosphere of the render.

Hey, thanks for the crits. Man. I had a rather difficult time keeping that smoke alive and now you're saying it doesn't play? Arrrghh. I have to think. :)

mmm . . . Looking at the other entries here most are very bright indeed. I wonder if perhaps the contrast between bright and dusky doesn't make a difference in the perception of the darker corners. Just a thought. I have to say I like the dim reaches very much. I'll have to think; see what some other camera angles show.

You could prbbably squeeze quite much of that image by playing with colors in post - nothing wrong with it being dark/dim, it's the gray part that is the problem. Try making the grays more blue, cold... or maybe warm ? Gray part just seems undefined, and boring to that - not that good, while it occupies big part of the image.

First off, thanks to Dan and Jeremy for this nice little challenge :)

Here is a lighting rough. Only omnis and spots, no gi or AO or area lights. I do use area shadows, though. Just tryin' to get a feel for now. Probably use wood bowl, painted wooden fruit, and earthtone cloth--might use real fruit, though.

Some nice stuff posted. I really like some of the more painterly feels to some of them.

I begin to grasp the concept behind the challenge. Or, at least, the approach that suits best at any rate. Calling this one 'Sunrise at the studio'.

Certainly the most complex setup I've used this one incorporated much of the experience gained in the last few days. Lights include 2 primary lamps, one set to edge the hard sun like lamp. 2 back lights set to single layer only. 3 filler lamps 2 of which are limited to single layers. And 2 reflection lamps to simulate secondary bounces. All of the lamps except for 2 point lights are shadow mapped spots. No raytracing was used in the render.

Trying to capture early morning first light and the promise of the new day.

And a screen of the setup

Kye, I like the colors you used, maybe the specularity on the apple could be lowered? Some of my favorites so far have been: Holle, 3Dworks, as07. I also thought the glass versions were really well done too.

Here is my second try, and maybe my final. I used about 16 lights, rendered in fprime. It's a black and white so I tried to make it look like a real picture but without color, used a texture for the bannana and kept the color in the gray scale.

Thank you Kye, I didn't use any specialized SSS shader. As Otacon say, I used some gradients based on distance to reference objects (nulls), to fake that effect in a very faster way. I guess this technique is applicable to any 3D package.
Otacon, thanks man! Your last test is nice too. What have you used for the SSS effect of your grapes? Btw, you are right. I've used that trick. As you know is faster than any SSS shader so far. I've applied also the same technique (http://www.cgtalk.com/showthread.php?t=176195) to simulate the radiance effect of the local scene and spinning lights for the distance scene lighting.

This all sounds like a great idea to me. i want o specialise in lighting and it would be a good way to practice. I was wonderin who would be making the scenes for people to light because i think it would be a good if it was linked with the modeling forum n people who want to specialise in modeling who could actually model scenes for us to light. I think it would be a great way for both modelers and light artists to practice.

There's another thread (http://forums.cgsociety.org/showthread.php?t=309853) about future challenges, and we definately want more scenes offered. If you want to put people together from a modeling (or texturing, rigging, or animation) forum and get them to volunteer some shots or scenes, we are interested in hearing about it.

Thank you Kye, I didn't use any specialized SSS shader. As Otacon say, I used some gradients based on distance to reference objects (nulls), to fake that effect in a very faster way. I guess this technique is applicable to any 3D package.
Otacon, thanks man! Your last test is nice too. What have you used for the SSS effect of your grapes? Btw, you are right. I've used that trick. As you know is faster than any SSS shader so far. I've applied also the same technique (http://www.cgtalk.com/showthread.php?t=176195) to simulate the radiance effect of the local scene and spinning lights for the distance scene lighting.
A color version:

gerardo, amazing!! very nice, bright and natural light.

btw., thanks for sharing so much of your research work in the LW forums! i wonder about those 'hairy' cherry stems, i newer saw this kind... looks terrific :) how did you achieve this effect? hd instance or photoshop?

hey guys !! :)

here my first render test. totally misssfast+simbiontxsi.
setup just for the main lighting, color profile, sss look
and grossly procedurals. bananas and some other fruits
have just a gradient for the moment.

nice, clean and crisp image! i love the contrast in it! maybe just try to give a little bit more light on the left side of the scene where the details of banana and grapes are lost into the dark...

Ok, here's an update. Perhaps a final update. I added more fill-in light...though it looks like some of the highlights on the bananas are getting blown out. I could have adjusted all this in Photoshop, but these are straight from the camera...er...renderer.

Of course, I couldn't leave well enough alone. I wasn't crazy about my light placement, and wanted to go for more of a natural light through a window look. So I did this:
