Is possible to rigid body simulations inside of 1 object

When you have many objects in blender it just completly craps out
(Try duplicating a cube more than 10k times)

I was wondering if there is anyway to simulate rigid body while being considered one object in blender so blender its self doesn’t die.

There is a way. Download the fracture modifier build and activate split shard island. set shard amount to 1. and there you go. or share your .blend file. I’ll be glad to do it for you.

I know the fracture modifier can do this but i try to stay away from it. I dont want to get hooked on it because it probably wont get added to master for a very long time… That is if it ever gets added.

Well I always have the regular blender, but i think its good to have the build on the side just in case.
