Hi
I see the smoke has benefactors and retractors about the thick, will be a difficult decission. You know from what side I am and what is my opinion about this smoke. Can I make a suggestion? In some ocassions of high velocity, the particles of smoke will be so much separated as you can see in this video
For that I suggest add another .eff for the smoke, one with TSmokeTrailParams system for the first part of the smoke for cover the holes between smoke particles. Would be nice, thanks for this games
