Indigo Renderer Forum

Im looking into material like on image i attached.
Is possible, that some of ISL nerds here can mimick this material and post for public use ?
I`d like to use this as "preset" material for fabrics in my scenes but im not able to mimick this material using blend material so i hope, ISL can handle this.

Zom-B showed mi this amazing thread so maybe it will be useful : http://www.indigorenderer.com/forum/vie ... f=7&t=7505

I have better fabric materials, but they run only on my custom renderer

Problem with the bump approach is the big energy loss from these materials (they have to be somewhat dark)

Etienne: I'm curious, can you please post here or email me some images or information about what techniques you are using?

Hi Dcm:
I'm looking into anisotropic material and fabric rendering now, should have some results over the next few days.

zomg happy people.

Oh that is REALLY nice, there is nearly no Interior rendering without fabric... so often used, but so hard to archive anything really realistic.
Thanks in advanced Ono!
I sent Thomas quite a bunch of interesting papers about that topic over the last months/year... hope there is finally something useful in there

They might look not so bright, but linear tonemapping is mostly in cause. The white one has 0 energy loss (see the white sphere in white environment)

This one could be close from the first image, with some tweaking

gal : very nice test, but they looks kinda plastic for my eye, maybe some small tweaks should help.

ono : anistropic ? Im curious...as far as i know, Fryrender and Maxwell are using custom "Nd".
Probably smoething like fresnel.

I think that using that standard testscene its gonna be hard to verify the shader quality... some (twisted) fabric mesh would help here

Hey Zom-B, just took a peek at your site... Very nice stuff you got there.. thumbs up.


Peace,

Sure. If someone could share some simple cloth or sofa model with me, in igs or sketchup format? I'm a very poor modeller...

I'll send you a model via PM, should be good for testing

Thanks for the Flowers Rich

I tried to pick Galinette's Passionated material and do some sort of parametric material without great luck. Any tutorial one can fallow to accomplish such a thing?

Tried to follow CTZn's MarbleStudio2D but it keeps getting me an error.

THAT

GREEEEEEEAAAAAT!

Thanks Nick!
