>>2819963Here's an example, I replaced the right side hair rigid bodies with 0.01 unit spheres with no other changes, on an otherwise working setup. The rigid bodies enter a glitchy "falling" state for like a second, then snap back to their position, and repeat. Yours look big enough though. Sorry, no idea then.
If they just fall off and stay on the floor like in your picture without glitching around then it sure looks like they're either given large movement constraints on the joint (there's rotation and movement constraints) which you generally want to be at all 0s for hair, or the top joint in the chain isn't attached to the head rigid body at all.
