SkyCamera
Marks the origin point for sky rendering. Place one in every map that uses a 3D skybox. Only one SkyCamera can be active at a time.
Notes
SkyCamera sets the reference point from which the sky is rendered. In maps with a 3D skybox (geometry built at a smaller scale in a separate area of the map to simulate a distant background) the SkyCamera is placed at the corresponding scaled-down position so the sky geometry lines up correctly with the player’s view.
SkyCamera is not required, but can greatly enhance even the simplest of maps.
Only one SkyCamera can be active at a time. If multiple are placed in a map, whichever spawns last will be the active one. This is generally not a concern since maps should only have one.
The 3D skybox is rendered 16 times larger than it really is, so any models or textures used should be scaled accordingly.
