Control texture by light angle

[rickard_didriksson]

Hi

I would like to control a texture based on the light angle of my key light. Or more exactly I only want it to affect what is in the shadow interactively.

I found a video of by "Blender Guru" where he does it in blender but I have yet to figure out how to do it in Maya/VRay. I will provide the link bellow so you can see what I mean. It is ca 18 minutes in.

Thank you!

Hi, thanks for posting. There is a way to do that. Use a VRayFalloff node in the diffuse slot of your VRayMtl. Link the VRayFalloff and the VRayLIght as in attached scene.
