ow I see. Sorry, that was my first time to post here. Anyway here's what I do with bump maps
> i use the texture on the surface
> then i add another copy in "in model" of the same texture
> i change the name of the texture to xxx_bumpX.jpg - the texture then changes to a solid color. (like with bricks texture, when i change the name the texture changes to a solid brown color) Is that what's supposed to happen when i change the name?
