   So I added a whole bunch of random paint swipes and it fixed the reddening thing. So my plan is to keep diffuse and AO in 2 different textures. Since diffuse is nothing but simple colors, I can make it incredibly small. The AO, specular, and masks will be put into one of those consolidation textures.
