Droping Balls


I’m trying to make a animations of balls falling on a plane. For that I used a plane emiting a group of 3 balls and a plana with a colison sistem…

But, I don’t know why, the balls penetrate the plane and themselves.

Can you tell me why this happen and how can I fix it?


add collision to the ball object you entered in the particle

That worked for the colision with the planes, thanks

But it didn’t work with the colision between the balls themselves

activate collision on the balls as well. If they are partially intersecting you may need more verts (add subsurf) to improve the collision detection.

Thanks guys, I did it.
