A dynamic loading screen without level streaming?

As of now for my project, I’ve just been fading to black and using Open Level to switch between the main menu and the different maps for the game. Now the loading times are getting long enough that I want to get a decent animated loading screen in, but I can’t figure out how to do that. My system doesn’t use level streaming, it’s all in completely separate maps, and the only solutions I could find for a dynamic loading screen involved level streaming in some way.

Really all I want to do is load a simple Loading Screen map, have it play it’s animation while the next level is loaded in the background, and then open that level once all the data for it is loaded.
