Hi,
I have a vehicle, and I want to do dust simulation when the wheels collide with the terrain.
This is a good example, well, before to crash the car. :lol:
Thank you in Advanced.
add particle system in wheel object, when you get some speed, then start emit dust 
mmmm…
I want to do emitter particles for several terrains, like sand, water, cement, rocks in a Scene.
This idea can work? or somebody have a better?
you can change material for emitter i think. You just need to check on that ground you are, and change emitter particles
