Re: mapping???

hey I had the same problem 2, I do it like this:

make a texture and a bumpfile in photoshop.  
load the texture in SU material and apply it in your model (and scale it like u want).  
then link it to vray with VrayLinkedMtl… then choose the material from the list u want to link. then go to vray material editor and now u can add a bumpmap etc.

Re: mapping???

Are both of you using the original version? The latest automatically links SU materials with V-Ray materials.
