hi would be nice if one mesh hits another one enough phoenix can detect this and generate dust, smoke. You just tell it how dusty is the collision surface and that way it can properly generate birth of dust more at impact and less away from impact zone. same for tire burn out etc i know you can do it with boxes near tires or black and white masks that generate dust but interactive would be easier and better Thank you
Thanks for the suggestion! Currently you could also look into discharge modifiers and also use the V-Day distance tex to make it more procedural.
Cheers!
