Fade Out Screen And Audio

Then it sounds like the border-widget will be your solution. Wherever you call the fade event from will want to send a similar event to the widget to begin the animation.

As for sound, I’m not very familiar with Unreal’s default sounds (we usually use Wwise). If there is a way to modify a Master Volume or even the volume of a collection of sounds, then you can adjust the volume over time to gradually fade out. You may want to make a Blueprint to manage some of these fades all in one place.
