A package that allows us to manage multiple cameras in our scene and create rules for our cameras
Virtual camera
Cinemachine does not create new cameras. Instead, it directs a single Unity camera for multiple shots. You compose these shots with Virtual Cameras. Virtual Cameras move and rotate the Unity camera and control its settings.
The Virtual Cameras are separate GameObjects from the Unity Camera, and behave independently
A good rule of thumb is to use a single Virtual Camera for a single shot.
