I'm trying to prepare velvet-like material in 2.57+0.1.2
So I need something like falloff or gradient texture but can't find it.
Any ideas?
Thanks.

Ok. Thank U. But blend must be oriented perpendicular to camera. Is it possible?

I'm sorry Yaroslav_L but IMO that is an unconvincing velvet shader, it looks too plasticy to me. Real velvet has a nappy roughness and appears soft and luxurious.

I don't think you necessarily need gradient textures or ramps or anything like that to make a velvet material. I made a quick try by abusing shinydiffuse fresnel reflections and mapping cloud textures to various channels, it is far from perfect but maybe it will give you ideas:

Of course there are other ways to do this too, just experiment...


P.S. I do agree with you that having some way of controlling falloff on a material would be nice to have, because for that purpose a gradient texture is a bad solution.

Here's a very nice silk (actually the best I've seen in Yafa). Maybe it will help. :)

Hi wizofboz and thank U for trying to help.
But IMO your material looks like silk - not velvet.
This is velet:

...because of short nap...

I really was looking after some glass here on forums that would work good in architecture. I couldn't find any good solution. After some time I finally got a glass material for architectural exterior rendering that I use from one project to another and really satisfy me. Since I never shared anything here, well - it's time to do it :]

Here it is:

I use it with directional lighting on glass panes about .005 thickness. Enjoy.

Hi In free time I make some attempt to velvet and these are my results.
I also in last time made a very good texture&material for the painted wood . In the file you also find my leather yafaray shader.

I just want to share some colorful gemstone materials..
All gemstones have absorbtion distance in real world scale - correct dispersion values(i hope so..) and "correct" IOR values.
Raise absorption values to obtain less colorfull gemstones especially to get a clear diamond.
I hope somebody can make use of it ;D
