Can you give us a picture of the map u map, tell us how you made your shader, and just give us as much information ans you can of what you actuallly did in the Hek process. You can also IM or PM me, I'm home all day for spring vacation! woot

Are your matirals # properly?
like
1,2,3 etc
not 1,3,2

I found the problem, it was a plane that had no material applied to it. Thanks for your guys help anyway.
