This is probably a noobish question but I just can't figure it out..
So I want apply a ramp to shader. I want the ramp to move around on the surface of the object when the object moves.
This works fine with the "Crater"-texture but VRay doesn't support this texture. How do I apply the same effect with a "Ramp" or "file"?
I can't create a "3d Placement"-node and simply connect it to a ramp/file. Nothing seems to work.
Thankful for any reply!
