Trying to replicate a rust effect on edges [solved]


#1

I have broblems trying to make a metal metrial with rust (secondary texture) around a a surface edge.

I read in Help that an inverted AO can help with this proccess but can’t set it up in the Alpha channel as sugested.

I’ve managed to set it up in the diffuse channel:

I remember watching the first video… just hopping to have an automated way to detect edges with AO in case I end up with a compicated mech model.

OK now I get it . There are two seperate materials assigned on the same object. Now the Alpha Channel makes more sense.
