I'm making a scene in Unreal Engine 4 and the reflections are coming out pretty grainy. Is there a way to reduce the grain or blur the resulting grain to give a less grainy result?
Some other pertinent information: I've tried this on two different machines of varying performance (both machines run on an different gen i7's. One runs with a GTX 570 and the other is a GTX 970).
I also noticed it on some of the example maps (reflections subway most notably), however it was far less pronounced.
