Velvet and Fabrics Materials

[Magicmez]

Hi All,

Does someone have some shaders or tricks to create velvet and fabrics materials in VFR?

Thanks in advance for your answers.

Re: Velvet and Fabrics Materials

Fabrics, and velvet especially, don't work with diffuse shading in the same way most materials do. In fact they kind of look wind up doing the opposite thing as most typical materials, so they become "brighter" as they fall away from view.

There are two ways to go about it, an easy way and a hard way. The easy way is to use the angular blend material and the hard way is to use the fresnel texture within the diffuse slot. When using the angular blend material, you'll want to have a darker shade of the material as the main material, and then you'll put a brighter shade of the material as the material to be blended to.

With Fresnel, its a bit more work, but IMHO maybe a little bit better results. In the diffuse slot you'll need to add a fresnel map. Then in the fresnel slot (within the fresnel map), you'll want to add another map, this time an Acolor map. Set the Acolor to the darker version of the color you want and then enable Invert (this is very important). The refract slot (back in the fresnel map) will also need another Acolor map. This time set a lighter version of the color and again Invert it. That should get you going.
