Main Camera

It allows you to adjust the camera angle, distance from the 'player' and the maximum fps that can be achieved on the device.

Fade Panel: loading screen or transition between scenes, you can change it here, place a black background, an animation or whatever you want.

Spawn Player in UI: allows you to show the 'player' in all windows, if you deactivate it it edits all windows and eliminates the Raw image that is responsible for displaying it.
