After collision physical bone will move out of parent

icqqq

I am trying to use physical bone and found that the physical bone will move downward due to gravity scale and become a separated bone rather than attached to the parent bone.

how do prevent the physical bone from moving? I just want it to rotate rather than translate during collision. And also want it to restore its rotation due to gravity after collision.

even I set the gravity scale to 0 it still move infinitely after collided with another physical body, which is not what I want.

Thanks

I haven’t used the Physical Bone myself, but I would guess that the bone needs to have a parent RigidBody or Physical Bone set to static. Then a ConeJoint or similar can be used to keep the Physical Bone in place and only rotating.
