This is probably something a lot of people are already doing, but I just recently figured it out....
I was bemoaning the lack of good object/material alphas with Maxwell because the mat and object ID passes were giving me randomly assigned colours that needed to be manually selected in Photoshop, which of course meant a severe quality loss of the edges of anything that wasn't perfectly sharp.
Then I realized I could borrow a trick from Vray and set the Mat and Obj ID colours to *pure* R, G, and B values to get two 3-mask alphas out of each of those render elements. I wrote a bit about it on my blog, been very useful to me anyway!
