Playing with sprite smoke and wanted to ask two questions.
1) Is it possible to achieve an effect like the one in the still image from a 2D Disney cartoon whereby smoke is underlit to give a dramatic effect?
Sprites don't seem to be affected by lights and if you colored the individual small graphic (which makes up the smoke ) to be underlit, then the underlit effect would be over the entire smoke cloud and not isolated as it would be in a dramatic setting...
2) I have been trying to get a very slow (almost hypnotic) effect with smoke rising using sprites. Can't seem to slow the smoke down enough to get that effect. I tried playing with the "initial velocity" and "gravity" settings with no luck. You could take a Hash smoke render and slow it down by time stretching it in After Effects but that is a cheat and it wouldn't look great.
Attached is a slow smoke "boil" from a Dark tree animation. Unfortunately it's not 3D. but maybe it gives an idea of the desired effect.
Thanks for any suggestions,
