Hi there!

I need to do a simulation with a lot of balls falling down. I think that the fast way to cook that is to make a pop simulation and use pop instance.

The problem is that I cannot find the way to set up the particle scale in order to get my instances collide well. And in viewport, once the balls are on the floor, they stopped rotating.

Is there a way to make my particles as big as my balls and to follow the inertia so they doesn't stop rotating??

Or maybe you know another way to do this simulation without a lot of time of cooking.

Thanks!

Hi,

All I could do for you is giving the random scale for each particle. For the rotation I think you need to use vop and don't know how to do it. Sorry.

Hi,

Thank you for the replay but that is not what I need. I know how to do that but I need all the balls to be the same size and collide with each other without intersecting. Thank you anyways

Have a look at the “popswithrbdcollision” example from the help files
or use something like the attached maybe

300 frames, 10000 balls ~ 8min on my good old HP
