Hey, is there a way for the dirt shader to ignore bump maps? I just want it to be applied to geometry regardless of the bump map applied.

Not sure I understand the question

You could try a mix node and separate the textures, if I got the problem correct.

exactly =) use mix material! that should help =)

when you apply a dirt shader it gets applied in the crevices of your bump map as well as the geometry, which you may not want.

Aren't you also blending all channels though with a Mix material? So I can't get 100% of the diffuse of mat1 and 100% of bump of Mat2. I'd only ever get a proportion of each, eg 50% of the dirt darkness and 50% of the bump (or 80/20, 70/30 etc).

you can use same texture in both material, also possible to use a multiply node with floattexture>1.0 to exaggerate the bump effect.

Float >1 is a good tip. I'm finding bump maps difficult generally though, switched to Normal maps.
