Just thought I would hear you out on this one before experimenting further:
Is it possible at all to add an alpha-channel to a texture in-game? I am playing around a bit with split-flags and I am adding the alphachannel as background. This would be the way, I used to make textures for HL, only the HL-engine wanted the AC-area to be filled with a certain blue color. Tried that too, didnt work. The game still renders the whole flag, including AC areas.
