Flashing images on screen, need help

[Tirfing]

Does anyone know how to flash images on the screen very briefly? I'm working on a horror-esque game. I've tried to switch to a scene and then exit fast, but it crashes the game. Is this the way to go and I'm just messing something stupid up or is there a different way that anybody knows? Any help would be appreciated.

Just thinking out loud...you could attach an InterpActor to the player so that it site in front of the camera, just a plane. And have a transparent material applied to it most of the time, but then switch the material for brief periods to get the flashing. No idea if that will work well or at all, but it's an idea and it could all be done in Kismet so that is a plus.

Could most likely achieve this with a PostProcessEffect. Research what happens when you take damage and the red damage material on your screen is shown.

Couldn't you also do this with a UI layer?
Also, you could maybe use Matinee to quickly move the camera to a new place in the level momentarily, but I think that might mess with texture streaming.
