This script will make an object appear or disappear during a scene.
The object must be set up with they Movable (under physics) and must have a customizer called Fade which is a bool and feeds into an output called child|blah:disabled. The blah will be a different value on each object.
The id of the scene it is associated with.
If checked, the script will make the object appear, if not check, it will make it disappear.
This is how long, in seconds, after the start of the scene the script will take effect. The effect will be undone when the controller broadcasts the end of the scene.
