Secondary Cameras

Especially if you have layered cameras in your scene (for example, a background rendering camera, a HUD overlay camera etc) you may want these other cameras to follow specific properties of the main camera, such as the rotation or field of view.
To make this happen, you can make these other cameras Secondary Cameras.

Creating A Secondary Camera

To create a secondary camera, add a Secondary Camera component to the camera you wish to follow the main one.
By default, secondary cameras will copy the field-of-view and rotation of the vehicle camera, but you can optionally specify different settings per camera view in the View Override Settings list.
