I am trying to map a simple texture map onto a cube, with an alpha map to take out any extra...looking to have a transparent cube with leaves mapped on one face, nothing else. Any tutorials out there for Alpha channels? Do they need to be black for what you want to keep, and white for the image to hide? Help.. also, I'd like to use rotoscoping for putting movies on objects, moving leaves, similar to the technique in RustBoy. Thanks.

Never Give Up!
