Rigidbody.inertiaTensor

Description

The diagonal inertia tensor of mass relative to the center of mass.

The inertia tensor is rotated by the inertiaTensorRotation. If you don't set intertia tensor from a script it will be calculated automatically from all colliders attached to the rigidbody. You can reset the inertia tensor to the automatically computed value by calling Rigidbody.ResetInertiaTensor.
