Still not possible I see - it's a shame, it'd be nice to add texture animated decals, especially if the particle affects haven't advanced from RF1 which seems to be the case. Any chance this feature'll be added?
Smoke dissipation, streaking spark effects rather than just some dribbled out static bitmaps, dirt being flicked up under tyres rather than just immediately creating static 2d particle cloud trails, far more convincing fire, slowly lifting dirt etc. as well as a few more specific uses I have in mind for what I'm doing.
RF1 didn't have animated smoke, it just had ever-expanding particle clouds of the same 2D image. Same with the seriously poor spark effect save that didn't expand.
