I want to realize an effect that darken the screen for about 2 seconds. when I overlap a trigger, the screen will begin to darken gradually. and to recover gradually in 2 seconds. Is there any way to make this effect using blueprint? Any help is much appreciated!

I would go for a custom post process Post Process Materials in Unreal Engine | Unreal Engine 5.2 Documentation :slight_smile:

Or a dirty way could be with a fullscreen widget…

You can use a camera fade node with a delay like this:

Yeah it can also be used to fade the audio as you can see in the screenshot, comes in handy sometimes.

For a short living effects like damage/pain or choke you don’t need Delay and two Fade nodes to reset fade back. Just set “From Alpha” to higher value than “To Alpha”. In other words - use only one second node with 1 to 0 Alpha for desired Duration and uncheck “Hold when Finished” of course.
