I want to shade cloth, which has a normal map for bigger wrinkles and I want to use something like the sampler infos facing ratio or even vr falloff/fresnel to drive a ramp in order to create this soft cloth feel.
Unfortunately none of this utility nodes seems to take normal maps into account. Is there a trick for the mentioned vray utility nodes in particular or does anybody know a way for mayas sampler info.

I found this here, but it does not work for me:

Thanks :slight_smile:

Hm, the VRayFresnel/VRayFalloff textures should work fine with bump/normal maps. Can you post a screenshot or a sample scene where they don’t?

Best regards,

it worked :wink: thx
The confusion came from the fact that the normal map looks a lot more extreme in the reflection AOV than it actually is, so that I could barely see any effect of my ramp (or a lot less than exprected) in the diffuse AOV.
I discovered that the vray falloff is pretty handy in that case because of its mix curve.
