Covering SSS

Hi, I have a fleshy alien, and for the most part, it looks pretty good. BUT, the problem is, is that it’s dirty, so there’s dirt on there, which normally would be fine, BUT, SSS seems to think dirt treats light like flesh.

Is there any way to set the amount of SSS on a certain part of a texture? I need there to be SSS on all parts of the mesh except where dirt is covering it.

I’m just trying to think of a better way to do it than doing 3 seperate passes (SSS, no SSS, and a greyscale rendering to show how the compositor should combine the two).

But it seems this is the only option…

I believe you should be able to do it in a single pass with material nodes . . . but you will still need a greyscale texture to mix the two materials.

ARRGGGHH!!! Why didn’t I think of that???

Thank man!

Because we all get brain farts . . .

Your welcome.
