Proc.Mat Update 1.2

This update finally gives you the opportunity to RGB on you Normal/Gradient Map Combo cutting half the memory footprint from RGBA at the cost of just 2 additional instructions.

Now TC_Default compression for Blue channel is way stronger then for the Alpha so be prepared to sharpen, contrast or increase the size of your gradient maps if need be. Or you could always use the Alpha shaders that I'll also keep as a separate download:

It feels like I've done all I wanted to with this shader, so now I'll just have to look at the tests and how you guys use and figure out if there's anything I'd like to add or fix. So feel free to share.

Cheers
