Hey Dave, thanks for the reply! Although I know a bit about Fractal Noise (enough to know how commonly it is used in After Effects; you’re so very right that it is very handy to be able to manipulate it for a variety of effects) I still don’t quite get how to go from basic fractal noise to a thick “rolling mist” that would operate as if it had fluid physics — or maybe it’s being faked with a wave warp?
I’ve tried looking for resources as far as turning Fractal Noise into smoke or fog, which is fairly simple, but I haven’t been able to find anything like that, if you know what I mean; it almost looks like a fluid rendered in 3D software.
