Rotate door around pivot with physics

This is just a thought. Haven’t tested this, but have you tried just putting a good old rigidbody with a box collider, setting the object origin to the center of the hinge and then freezing the unwanted rotations (likely the x and z axis) on the rigidbody and freezing the position completely??

you can do this through simple parenting. just add a rigidbody with only y rotation constrains unchecked. parent would be the hinge location and the door would be the child.
