Alpha masks are fun, but woaaah takes practice to get good results from. I naively thought it'd be cake walk, but sheesh was I wrong. I have nothing but respect for people who can make hair look good with just a few polycards and lots of alpha mask and paint trickery. If my guess is correct it will be more color variety and shades in the hair when I paint the spec map.

Getting quite a bit of matte lines, so I think I have to go in and clean near the UV edges and make sure something isn't either pure white or pure black.

Here's a first stab at it.
