Hellya, I#m trying to creat digital silk and I'm failing
Is silk a BRSDF effect ? Backlightning ? Whats the scret behind
phtorealistic silk ? :bounce:
I wannna know it *heeeeeeeeeeeeelp :wip: :wip: :wip:
wanna warp a band of silk around a hat, got the mesh, but can't get a satisfying silk material....... using Cinema 4D XL 7.3

Here's a tutorial on how to make a silk material in Max. Haven't tried it, so don't know how good it is. But it might help you on your way.

Have you tried using incidence angles? :)
Using gradients with incidence angles should create the effect of silk - ie. the effect of the variation of colours around folds and things.
I haven't really used C4D, but I'm sure there must be a gradient/ramp option that can do this ;)

It was a long night, but i got it........
Yeah the trick are rampshaders in oren nayar material with ansiotropic highlights...
and i added a brsdf fake shader in the LumChan.......

Post a render, I'd love to see how it came out :)

Here is the material test render :
All matreials in this scene are procedural exept a small (25*100)
environmentmap for the silk.(WIP)
Silk is a OrenNayar shader with:
- 3 Highlights : a very soft one covering 75% of obj. surface
a mid one covering 25%
a hard one covering 5%
all highlights have somooth 100% falloffs, have no blooming
and are anisotropic highlights.
- In the LumChannel is a brsdf fake shader(ChanLumby Naam)
multiplied with a fresnel ramp shader
- a ultra fine noise is added with +5% in the bumpchannel
- a 25*100px b/w environment map is aplied
maybe i'l add a slight tubulence to the colourchannel
