Naah, I did this using fixed function pipeline

Biggest problem I have with this version is the fact that the effect is completely "flat", real fire is volumetric which is why I used render to texture to get the true volumetric feel that fire and flames have. If you would place this effect in a 3D room and rotate around it you'd lose any sense of realism it would look plain flat and wrong.

It's flat yes. Would I want volume I would use a particle system. For distant fires, Unreal1 style procdural fires, or like the fire behind the glass on the first level in Q3 etc. this will do though.
