Hey!
I was just looking at all the source to find a way to handle that very feature. What a new years surprise it is to see you’re already onto it! 
Any luck so far?
The reason why I want to manually stop the loading screen is because I use a few heavy assets that generate dynamically after the main level load, so I get slight hangs as it finishes up.
Not so good for the poor players, to think it’s done loading when it indeed has not. Heh.
