Hi All!
I was playing around with particles and I would like to ask you some advices.
I have a source sphere which has some particles on it. A wind Force is trowing the particles in z direction towards another sphere (on which a collision node will make them to slide away).
1) How can i make particles sliding even on the source surface? I tryied with a collision particle node but, of course, it doesn't work, since the particles are genereted randomly from the source surface (and it doesn't count as a collision) thus, as the animation starts, the particles pass trough the sphere. I guess a creep node is the answer but I'm not able to find out a solution.
2) Is there a way to prevent the wind force to affect those particles in the source hemisphere not facing the force?(I mean those particles that should be protected from wind by the sphere volume). I guess a group node makes the trick, but which expression can I use to group them?
