Is it possible to detach physics-activated meshes from the parent and let them go their way. See:

Hi @maz

AFAIK, it’s not possible to break a compound physics shape. If you want to break connections, you will have to create a constraint and at some point, break that constraint.

Ammojs supports `PhysicsJoint.DistanceJoint` which should be pretty much what you need. Then, set an impulse threshold for breaking.

And apply an impulse to break it.
