So I have a road sweeping machine that's doing its job, and I would like it if the road surface changed where it passes; a simple from dry (diffuse) to wet (glossy) would suffice...
Except I can't figure out how to do that. So, Juanjo, buddy, is there any way to have a node that uses a reference object to change a surface? Like the "mix material" but driven by a null or whatever instead of a texture?
Thanks!
