I'm new in blender, and I am stuck in the progress of my project. I want to emit particles from an object (done). Then i need these particles move on the surface of this object randomly (turbulences).
I have duplicated my emitter object, and i scaled up a little (ALT+S). I put it in collider. So now, my particles are stuck between these two objects, but the simulation time is big.
I just want to know if there are a better solution to lock moving particles on surface.
Thanks! Best, Vincent.
