Mason-> I'm using my own 2D game renderer. It also does alpha and supports image alpha-masks (like PNGs). The problem is that this game has super-mega-tons of frames for each character. So each character will use 8 bit images with their own palette. If I give them all alpha masks for every frame, it will double the size to 16 bit. Becco_UK-> The Firefly renderer places garbage in the background color, even when saving as PNG. This can be seen if you take a FireFly render into a paint program and use FloodFill without any tolerance adjustment. It's fine for art renders, but not good for games, where I would have to filter 1000's of images for 100's of characters. I'll probably just have to accept the glitches and just touch-up the important frames (like walking/standing) manually. I still appreciate the help though, Jiia
