When developing Unity content for Leia displays, it is common practice that developers will want two separate cameras: one to render the 3d scene, and another to render the UI on top of it. This has several benefits, including ensuring the UI is always rendered on top and enabling having different lighting and camera settings for the UI than for the scene camera. The MultipleCameras sample scene provides an example demonstrating how a multi-camera setup can be implemented using the Leia Unity SDK. The sample scene can be found in Assets/LeiaLoft/Examples/MultipleCameras.
