alpha maps as a separate file...
ok as far as I've read, i havent found an answer yet suitable for what I need. I have a tree texture map that I need an alpha channel for. In maya I can use a separate file for the black and white transparency but in Unity it doesn't work. HOW do I use a separate file for alpha channel?
okay, so I found this THIS but I followed it to the letter and got bupkis. I still get the stupid color around my tree, the transparency WONT WOR$$anonymous$$! I have the alpha channel set up with the selection and everything. WHy the heck is it SO HARD to get a freakin transparency set up? this is ridiculous....
If you actually followed that, then it would have worked fine, because that's essentially what I do (though I use the Fla$$anonymous$$g Pear Solidify filter rather than the AlphaUtility actions, which accomplishes basically the same thing) and there are no issues. It's really not that hard.
You don't, you just put the alpha map in the alpha channel (using Photoshop or whatever). Although technically you can write a shader that uses a separate texture for alpha, but there's no reason to, and a good reason not to (namely less memory usage).
