i am trying to simulate a bunch of helium balloon released and floating up towards the sky. Something like in this video: balloon_release. Right now i am not concentrating on the cloth simulation. First i am trying to get the motion of the balloons right. I tried this using rbd, but i am not able to get the right motion of the ballon in the air. I have attached my test file. It is a very basic setup. The problem with it is that the balloons are rotating a lot after they are released. I am not able to control their rotation. I tried rotation stiffness but it doesnt help.
Can someone help with this?? Am I in the right path or is there a better way to do this simulation??
