Watchers
You can add custom Watcher objects that can trigger the Loading Screen
Using an Actor
In this example we're going to use a simple Actor Blueprint that will ask the game to display the Loading Screen, we add the actor as a Loading Screen Watcher and add the Loading Process Interface to the Actor Blueprint
Setting up the Actor
If we set the Return value for the Should Show Loading Screen function to True the loading screen will be displayed as soon as this actor is spawned.
The function doesn't always have to return True, you can use a bool to determine when the Loading Screen should be visible.
Limit Loading Screen Duration
This will show the Loading Screen for 4 seconds only.
