These nodes need some better documentation.
So that black screen seems to be caused by ‘Set Splash Screen’ -> ‘Show on Set’ checkbox.
But I can’t figure out if you put it in the level that it’s loading away from, or the level you load to. I can’t get a consistent result.
But I have seen it… and it looks like a big textured window (in my case white) out in steam compositor. Which is… not the best result, but adequate for me to stick a loading sign on to let the player know the game hasn’t bugged out.
If only I could actually get it activating reliably.
I think at some point I also threw in a stereo layer node, and that might’ve made a difference?
Like I said, this feature needs documentation.
