Vray Material Repository: Gathering of ideas

[DaForce]

This thread is abit of a carry on from what the thread below turned into.
http://www.chaosgroup.com/forum/phpB...ic.php?t=16108

The idea is that we create a database of the best vray materials similar to the maxwell material site linked to in the thread above. It could also be made part of the ChaosSquid

We will need a light box type scene similar to Maxwells to show of the materials in a fairly neutral environment then perhaps some mini arch scenes (interior and exterior) to show how the materials would react in a production environment.

So before we jump into the materials we need to get the scenes done first.
Do we rip maxwells idea? but with a slightly different setup and model? (lets face it theres is pretty good)

For the mini arch scenes, do we use LWF? vray sun and sky or direct lights?
What would be needed...etc..etc..

These are the things we need to brainstorm about first to get an ideal set of scenes. THEN we work on the materials.

Some ideas I have had:
Lightbox: Would be similar to maxwells idea, so all properties of the materials can be displayed in a neutral enviroment.

Mini Arch scenes
Interior: We could have a basic room modelled or maybe a couple so we can display floor, wall, ceiling, glass, curtain, fabric. leather, metal and ceramic materials (to name a few) in a more useful enviroment.

Exterior: Perhaps a part of a house which would include some road, grass and perhaps pool areas to be able to show off those sorts of materials.

Im thinking for the mini arch scenes, we would need multiple cameras in the scenes located specifically to see the material at its best.

So post your ideas/comments/thoughts

i think keeping it simple (K.I.S.S rule applies) would be best

[mmikee]

Excellent Idea ! Ill give it some thought. I do have a few custom models that I could donate for the interior. And a couple decent mats to contribute.

Yeah you may be onto something there CJ... maybe just the lightbox and leave it at that??
Lets see what other people think.

Excellent mmikee excellent

[jacksc02]

dont you hate it when im right daforce

[DaForce]

I will let it slide this time

It sure does mean alot less work.. hahaha

Do you reckon the maxwell people will be shirty if we completely pinched their little model?

[jacksc02]

maybe we could ask?

For the nitty-gritty physical light response of materials on the little bits filling out our scenes, it's great. But, I can't see siding, shingles, stucco, concrete, etc. on a toy trailer hitch. So... what do we do about the bread-n-butter arch vis mats??

[jacksc02]

good old chamfer box always works well for bread n butter arch stuff

I think there is a good issue to look at here - mapping. If you have a metal or glass or a little sss on a monkey ass that you want to test thats one thing and yes the "maxwell member" is great but once you need a bitmap applied that adds another level of detail. I paint many of my maps now and I paint them by unwrapping the uvws, adding grime and funking them up a bit. Not only that but most of the time I have to alter a bitmap to get rid of tiling and all that so scale is an issue. Or do we limit ourselves to non tiled bitmaps?

Mostly what I am driving at is that I think we may need 2 objects for archi work so we can really understand the scale issues one object with a set scale that is very small (close up) the other that shows the object running a course so tiling can be addressed. Sorry I am a bit sick right now and rambling.

[CCS]

IMO, that gets us off into the theoretical, esoterical world of Maxwell. All good things to look at, sure. But, most of us do arch vis. And almost every mat has something in the diffuse channel. And the materials need to be at least 2' - 5', if not much larger, in order to really see them.

I still think we need 2 scenarios if for no other reason than scale.

[DaForce]

Yeah ll this then falls back to the mini arch scenes, or some varient of them.
I still think these are necessary to full visualise how the materials will look.
And given what you guys are saying I think you would all agree.

[Sawyer]

Yeah I think a little street scape with winds doors and maybe panels (think windows but not glass of different sizes for scale issues) that could take anything you put at it.

Maybe a special lighting or scene for SSS materials ?

[DaForce]

I think the lightbox scene would suffice for SSS materials. Seems to work rather well for maxwell.

But i guess you might need something with a stronger direct light.
