Ok, this is probably a stupid question, but I need a smart answer. On my map, how would I make it where when you start the entire map is black out, not just grey?
You could point the camera to a black sky...
or you could use that black mask in your subject. I think it's Cinematic - Apply Filter, or some such action. Put that in the Initialization trigger and you should be fine.
Oh, lol. In that case, it's in the map properties stuff. Like one of the tabs next to the loading screen. Uncheck the "Map is partially visual" or whatever.
