It is affected by proximity, but has no direct relation to it. The 
geometry of the surface is more important than distance...a very thin 
cylinder compared to a plane for example. And objects without insides 
will be invisible to it, since they contain no volume. It's really 
nothing like the proximity pattern, more of a blurred object pattern.

Hmm, I'm going to have to try using smooth noise instead of random 
samples in the patch...I think it would eliminate a lot of granyness.
