This comment extends to Multi-Player. Define n to be the amount of players. For each dynamic camera, there must be n-1 duplicates as one camera cannot track multiple players.

After some thought, a better implementation might be having one instance of all fixed cameras and attaching personal cameras to the players. On body_entered, modify the corresponding player camera to mimic the nearby fixed camera.

Reminder: Camera3D registers itself to the nearest SubViewport via ascension.

Have a World set of Camera3Ds which will (alongside their Area3Ds) signal to individual Player cameras when triggered. So, each player will have 1 static camera and 1 dynamic camera which will, upon trigger, copy the triggering camera's position (and tracking).
