Today had a bit of a challenge. Took the easy way for now but I hope to find a solution in the future. I have several piles of sand in my scene. Each similar in model and texture. But I need different transparency maps on each one. I thought of using a switch to drive the alphas to their respective objects but no dice. For now I have seperate materials for each. I've made a few inquiries around school. I might even post on a forum or two and see if there is a solution.
Guess I sort of solved it. Painting black and white images instead of alphas. Much better for the work flow. Thanks Russ. Though I do feel kind of silly now that I was trying to do it the hard way. Live and learn :).
