There are two things I don't understand about the dirt map:
1. Subdivisions seem to broaden or limit the area of the dirt, even though that's supposed to be handled by distribution. Shouldn't it only effect the noisiness/quality?
2. If bias values are too high, dirt is showing edges of the object, just as vray edge is doing. This makes it hard to control if I want more bias. Why would it make polygons visible?
