GMC truck model -FR

[Dr BeN]

first of all STOP TAKING PHOTO'S from real cars and posting them as CG images !!! :scream: no just kidding ;) reaaaaly nice work

but i realy like to know how you brought your MAya 4.0 scene to max(FR) did you use OBJ because as far as i know it only supports poly's ? and if so this scene must be HUGE !!! ? so did u use any trick ir tweak ? or do just have pure SGI power ... well i don't so it would be nice if you share your little secret with us ;)

i personally use maya 4.02 and i got MR too but a can't help myself .... i love the Cebas renderer !


thx


( will there be some animation on this truck ? commercial ? where is it shwon ? Us only ?--->i live in germany ;-)

Well, i guess the trick of importing was this: I exported a scene into *.DXF format. Turning the whole thing to poly yes. It is only about 200 000 poly in maya. But when imported into max, it had to be readjusted to max's coordnates, and all the mirrored faces had to have normals flipped and assigned smoothshading groups.
:buttrock:
When the thing was brought in to max, it had triangulated all the poly. Doubling the number toi about half a million.:eek: but, then I used optimize modifyer and quadrangulated all the poly back.
And then all the HDRI map configuration and FR configurations.
This work was completed on dual xeon 2.4 ghz with 2 gb of ram and Nvidia Elsa Gloria 2.
For rendering I used 1 dual xeon 2.4 and 1 p4 1.8. Rendering time per frame around 18 min.
Here is some earlier tests.

This is and image where I have rendered the HR Ray cast samples to see wheather or not all rays bounce in the right way.

[Wiro]

Not bad! Nice model and render. One thing I noticed though is that it looksl like it's floating. This is due to the GI'd shadows not really connecting to the model. Try to increase your min/max samples to get more shadow detail.
Also increase your RH rays to decrease artefacting.

There is also some apparent aliasing going on, especially on the front fender. Did you try to use the adaptive AA?

Very very very nice. :thumbsup:

Only things that seem odd are the front seems to feel 'one piece' around the headlights, grille, and hood, I'm sure the tolerances are just tight there, but it just kind of feels CG.

Also, everything else looks really tight, so I bet this is just how the truck is designed (haven't seen this year's) but there seems to be a 'wave' you can follow with your eye from the front bumper to the back, most noticeably along the doors at the window line. Makes it seem warped or distorted somehow. But then a lot of cars are doing odd things like that now, so like I said, if it's on the real car, oh well :)

Anyway, looks great, surfaces have a good feel.

[EighthDecay]

if I didn't know anybetter I would have thought this was real,, FR does some amazing lighting,, your model looks perfect to me. I don't know the Vehicle very well either,, keep this good stuff coming...

[diazgl]

excellent job man. The front looks amazing, like it was stripped from a photo. And a little question, or rather remark. Did you use specularity? Cos I think you did, whereas, you should remove (in my oppinion) all specularity and luminoscent planes (like windows) to be reflected, or make a sky and road bkg.

[Dmitry]

yeah, here is a link to a QTVR of this car. You need broad bandwidth to download the file its about 8mb.

That's way to nice, finally a jeep, everyones making sport cars, bah

I just love it !!:thumbsup: :thumbsup:

[ToddD]

Wow! Very impressive work, can't say anything negative really. Wish I had the computer you used to render, pretty quick rendertimes!:beer:

[dlindwall]

Good work. Are you a student or professional modeller. It's good to see work from artists in Vancouver.

[Dmitry]

I went to VFS (vancouver film school) some years ago. Now I work at the production studio doing all kind of modeling, for still life, environments and scene sets. This project came under way recently, as my studio does not do this kind of stuff, and they are just trying out new criteria.
I cant say Im a super professional modeler comparing to the fantastic works Ive seen here. But I consider my self a pritty good artist.:airguitar

Dmitry - This is looking great realy great :). I have few comments/suggestions about this model :

1. front of model (headlights) is just maped image ?? right ? (front grille is also maped ??)
2. GMC logo on front grile is also just a map on one box object ?
3. front whhels (on first image) are way too much turned to right ?? I don't think that you can turn wheels so much :)).

BTW i'd like to see back view also and i suggest you to make gemoetry front lights and that maped parts then would be much much more belivable IMHO and then you can show bigger resolution on close shoots without revealing "secret" on maping lights :).

Still this is realy great model.

[Dmitry]

Well actually the whole thing you named is modeled. The light are 3 layer model, as in transparent glass, middle orange glass, and then the back light chrome. The grill and the gmc sigh are also modeled, they have chromatic reflections on them.
I will upp the other views of the car shortly.
Thanks.

[dmcgrath]

You are a fantastic modeler and quite competent on the rendering as well. Only thing is that the grille looks like it's too plastic. You got the chrome perfect on the wheels. But, in the first shot, the lights look mapped on and the grille chrome looks like that chromed plastic. It wouldn't make any difference if you animate this truck. If you just have still shot to do I would say rerender the grill with higher specs in it and comp it into the scene with p-shop.

OK then , sorry :).But lights and grile look soo flat that looks like they are just maped to flat polys :). Maybe diferent camera angle would reveal more.

BTW i forget to say that I don't see brake discs inside rims or brakes ??? Are they also modeled and it is too dark to see or you didn't model them :)?

BTW what version GMS is that ??

I'am not expert about GMC but only one on their site what is similar to this one is GMC Yukon XL. Is this that model or something new ??

yeah i must say this model is still needs improvements, i just didnt have enought time before the dead line. Anyways, the chrome needs to be worked, and the lights too. Well the break disks are just not there, i made them black. As to the model, it is GMC - Youkon Denali. Not XL.

[Matt]

Very nice work. I like the reflections a lot. Some areas look a bit odd (Grille has an odd spot where the holes seem to repeat in an awkward pattern, but who cares, it's probably the angle of the render.) 3 and 3/4 stars out of 4. :D

[Skyraider3D]

Great model! Very realistic!
Try rendering it against a nice photoreal background!

But... are you working at 1280x1024 resolution or something? The wheels seem a bit squashed...

Yeah Actually Im working in 1280x1024....didnt know if it makes any difference...I will upp some new pics today

[Dmitry]

Hay guys here are some new images of the GMC, these are not modified, just from a differend angle and different spec.

[Dmitry]

[Dmitry]

there are no insides as I had no time to model it..imagine modeling the suspension and discs and all that. I will in a future.

[Skyraider3D]

about the resolution...

1280x1024 is 1.25:1
while any other resolution (for example 1280x960) is 1.333:1
So what appears circular on your screen, will appear squashed on another
However if you uses 1:1 pixel aspect ratio, and made the wheels "mathematically" round, then it should only appear stretched on your screen... So check your render output pixel aspect ration :)

PS. Smack a sunset background picture behind those last renders! ;) Lovely lighting! :)

hay thanks for aspec ration, i'll check it out. The sunset is actually an HDRI map...quite a view in animation. But when its changed the whole scene is lit differently. This scene has no lights, its lit with hdr map.

[ilasolomon]

hi!
very nice work, haven't much to say... :)
but, forget about sunset
use a studio env. with a large white illuminated plane over the top
something like this, this method is classic
outdoor rendering is good but require more works. needs env. ref.
cheers

[JacquesD]

Very nice modeling, I would work a bit on the reflection, specially on the windshield.

Keep on. :)

[NuclearwavE]

Krutaya model, Igor mne pokazival ee..:thumbsup:

can you tell me more about this studio env, cant really understand what you mean.

[ilasolomon]

ok, may this pic helps:
see http://www.cgtalk.com/showthread.php?s=&postid=75815#post75815
for the result of this method.

[Dmitry]

:bounce: Hay could you tell me the rendering paramiters for that?
Im using FR - Final Render, and hdri maps, and that is a different procedure. Ive never seen this illuminated plane before.\
Dmitry.

:buttrock:

[Sevarf2]

I love your render. Good illumination.

[ilasolomon]

well, hdri illumination is good, but maybe putting a wide plane
over the car & using the raytraced surface is a good idea
just with an illuminated big box over the car, no parameter!
let the surface of car reflect the white plane...
& important thing, just don't let the plane casts shadow.

[Dmitry]

I'll try that out...but with hdri you get all kinds of reflections, not a single color. Well, Im woking on a different approach to the fr hdri rendering, so I'll see where that takes me.
Thanks.

[JacquesD]

HDRI works good for cars reflection but it's better to put in environment regarding the details and color you find in your HDRI image, otherwise It won't fit.

Good work BTW.

Keep on. :)

[ilasolomon]

THE RIPPER: is it your work?...awesome...where can i put some
stars for you?! :) u r go(o)d

[JacquesD]

Yes that's my work ila_solomon thanks.
I just wanted to show Dmitry that it works with a simple environment too.

[cybertm]

For everyone posting these images could we see some Edged faces snapshots or solid wirframes? thanks.

[erikals]

:wip:
Watch out, here comes Mister Picky! I think the wheels should be more "merged" with the pavement. Real wheels are never 100% round.

Otherwise, very neat.
