public Vector3 inertiaTensor ;



The inertia tensor is rotated by the inertiaTensorRotation. If you don't set inertia 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.

// Expose tensor of inertia to allow adjustment from
// the inspector.

using System.Collections;

public class ExampleClass : MonoBehaviour { public Vector3 tensor; public Rigidbody rb; void Start() { rb = GetComponent<Rigidbody>(); rb.inertiaTensor = tensor; } }
