hello there,
I have a car which is riding on the desert, and I need to create a trail dust. this car is going to be use in different shots. therefore we are thinking to create some particle emission depending on the car speed..
the emission rate would have to be linked to the car's velocity so it doesn't emit when it's not moving, and emits less when it's moving slowly?..
Does anybody knows or has and idea how to achieve this type of effect?..
cheers.
