UDK Citadel starts immediately with a splash screen...

…but in my app I get almost 7 seconds of black screen (that applies to Tappy Chicken and Black Jack too, both made with UE4). How can I show a splash screen instantly, as Citadel does? Please help me, I´m driving myself crazy with this issue! Thank you very much!

You can add a movie to play when your game starts while your level is loading.
I also want to know how to add splash screen as soon as it starts.
