This is a very general question and I am looking for some ideas/hints/directions.
In summary, I need to simulate what happens when horses run in desert, i.e. at each foot step ground particles rise up then fall slowly (maybe with some disturbance too). I am not sure what the right way to simulate this effect is: this is not particles simulation because the effect should look like a contentious volume and not particles, however it's not also smoke simulation because particles might fall quickly on the ground, i.e. they won't suspend too much in the air flow/turbulence created. I “think”, maybe a particle simulation should be created and use it as a smoke source, but again, the smoke simulation must be configured to fall down quickly?!
BTW, the same “effect” occurs when you drop a heavy box on the floor, when car wheels go very fast, etc.
Any ideas will be appreciated
