Class CinemachineFreeLook

A Cinemachine Camera geared towards a 3rd person camera experience. The camera orbits around its subject with three separate camera rigs defining rings around the target. Each rig has its own radius, height offset, composer, and lens settings. Depending on the camera's position along the spline connecting these three rigs, these settings are interpolated to give the final camera position and state.

OnEnable()

Updates the child rig cache
