I’ve been playing about with node only effects for rust recently. While I can get a really nice rusty effect I have no real control over where the patches are applied, I’m bound by the underlying texture, musgrave or noise.
Is there a way for verts to attract a material effect with paint or weight? To mimic the way rust tends to grow from edges and corners. I’ve only tried a little painting when messing around with sculpting, and I know nothing about weights yet.
If this is possible could someone please nudge me in the right direction, or is there another way to achieve this?
