Hey everybody,
It’s a very strange request and here is the situation:
I got a point cloud which contains roughly 1 million points. For a scientific purpose, I need a ball to hit this point cloud and the ball should be bounced. Thus It requires A million sphere colliders and could I attach those colliders into one gameobject by code?
Thank you very very much to all of you.

Unity current ships with PhysX3.3 which has a 260k limit per scene according to this

So you can’t have a million sphere colliders.
