Ray falloff

[gregvfx]

Hi there,

I wish we had a falloff map that could use the Ray direction, to be able to have the reflection and refraction to shade the same way the camera z does. Would allow to use the double side material with a back face material transparent on a "solid" object to work in reflections. My goal is to fake paper thickness with a shell modifier on a single side poly with the help of a towards/away in camera z. It works pretty well in camera, not so much in reflection, I guess it is also not working for bounces of Gi. If relative to the Ray direction it should work in most cases. If someone has found a way to use the double side mat and still have the feeling of a paper border I would be glad to know!

Can you show some images of what you are trying to do?

Ok I do that on Monday morning.

Actually it seems to work fine with the good old falloff... maybe it's using Rays direction instead of camera.

Can you confirm?

The Falloff texture works with the ray viewing direction, yes.
