centerOfMass and local coordinate origin
Is there a way to set the origin of the local coordinate system of a rigidbody equal to the centerOfMass automatically calculated by the Unity engine for a MeshCollider or complex of primitives?
I don't want to arbitrarily set the centerOfMass, since I want to use the auto-calculated one, but I want to apply rotational forces relative to the centerOfMass.
I'm using addRelativeTorque to apply rotational forces.
Thank you for your time, please ask me to clarify if necessary.

You could add an intermediate transform to act as an offsetter. E.g.
var offsetter = GameObject(transform.name + "Offsetter");
offsetter.transform.position = transform.TransformPoint(rigidbody.centerOfMass);
offsetter.transform.rotation = transform.rotation;
offsetter.transform.parent = transform.parent;
transform.parent = offsetter.transform;
