[HOWTO] Scene Transition Manager Order of Events

The Standard Scene Transition Manager runs events in this order:

When leaving the scene:

The Standard Scene Transition Manager immediately triggers the leave scene animation (fade out) and invokes the Leave Scene Transition > OnTransitionStart() UnityEvent. If you've specified pausing, it also immediately sets Time Scale to zero.
After the Animation Duration, it starts loading the next scene (asynchronously).
After the Min Transition Duration, it considers the "leave transition" finished and invokes the Leave Scene Transition > OnTransitionEnd() UnityEvent.

When the leave transition is finished *and* the new scene has been loaded:

It immediately triggers the enter scene animation (fade in) and invokes the Enter Scene Transition > OnTransitionStart() UnityEvent.
After the the Animation Duration and Min Transition Duration (whichever is higher), if you've specified pausing, it immediately sets Time Scale to one. Then it invokes the Enter Scene Transition > OnTransitionEnd() UnityEvent.
