Although why is it that in many games the fire or smoke partials appear to use a few large particles rather than a bunch a small one if its faster? Do those particles not use an opacity map on them? I'm just going off observation. One more thing. I only just…

Games are a lot different than rendering, in realtime engines they have different methods that are technically less accurate but are much faster. For example a realtime engine might only go 1-2 planes back before reporting back the color…
