Is there any way to use a TGA w/ alpha channel, _AND_ be able to blend it without using sorting?

RPGman, to awnser your question : no. At least in OpenGL the equasion for blending is basicially

Factor1 * SourceColor + Factor2 * DestColor

You prolly already knew that, but since the source/destination colors are dependended on to make the final color... the final color is dependent on those colors AND more specifically what order they were in... if you rendered back to front, your blending would look correct, and front to back (w depth buffering enabled) you wouldn''t get any transparency at all) It''s kinda complicated but to quickly awnser your question again no. I would reccomend re evaluating what you wanted to do, and then think of how to render them. Alot of transparency is just simple objects such as explosions or smoke, and if you just rendered those in a seperate pass you should be GTG. Ither way I hope it helps!
