Hey Farshizzo,
Thanks. I might need something a little more... I'm trying to overlay a few mud splotches on top of the default texture of an object, but they need to be erasable on an individual basis. It seems the easiest way would be to create images of mud spots on individual textures with alpha masks so the original texture shows through. Then I could just remove each individual mud spot by removing the particular texture. Does this sound feasible?
I suppose the grayscale mask could be made to work (though probably a bit more cumbersome). But I need to be able to blend an arbitrary number of textures...
Thanks again!
-Josh
