/// * Place the `VRTK/Prefabs/ControllerRigidbodyActivator/ControllerRigidbodyActivator` prefab in the scene at the location where the controller rigidbody should be automatically activated.

|
|
/// > If the prefab is placed as a child of the target Interactable Object then the collider volume on the prefab will trigger collisions on the Interactable Object.
