Grainy or Pixelated Reflections in Unreal Engine 4
interpolator
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.

You can also adjust the quality of the reflections in your post-process volume.
The noise because of the screen-space reflections becomes less noticeable the more noisy your textures are. Since your texture has no noise at all, the grainy reflection is readily apparent.
