How would you simulate the paint sprayed by a spraypaint can? It should be animated as hitting a wall covered by a stencil, so it must have some kind of gas-dispersion effect when it collides against the stencil and the wall. I'm working in Cycles, and paint colour is black.
I mean not simulating the paint getting sticked to the wall (that can be made with dynamic paint) but the paint flying through the space in between the spraycan and the wall. That's why I ask about particles system and not dynamic paint.
Would a smoke simulation solve the issue?
