“Fullscreen” seems to work, somewhat. I have “Event Begin Play → Command (fullscreen)” in all 4 level blueprints of my demo. The interesting thing is that it works on the first load of the main menu. When you enter a new level, it doesn’t go full screen. You have to reload the level, and then it recognizes it. When you exit back to the main level, the fullscreen command no longer works. Here’s a video showing what is happening. IT seems like sometimes it is working on begin play, and other times it is not. Thanks!
