    Flickering Material Reflections / Roughness

    Following the Intro to Level Creation tutorial, which is going nicely. Unfortunately I am encountering an issue with the materials where the reflections flicker as I move the camera. The problem seems to be in the roughness map, as when I disconnect the roughness from the material output, the problem goes away. After searching I have found a few other instances of this issue, which seemed to be resolved by deleting the skylight/reflection capture and rebuilding lighting/replacing. This has not worked for me. I have not changed any settings from the default. Anyone have an idea as to what might be causing this issue? I have included a video of the problem below.

    EDIT: After further investigation, I believe I have narrowed the problem down to an issue with screen space reflections. When SSR is disabled, the problem resolves. Does anyone have an idea as to why this might be the case? Additionally, anti-aliasing does not seem to be working in my viewport or in-game. Jagged edges are still visible no matter the anti-aliasing setting.

    SOLVED: Screen space reflections were causing the issue. The fix was to enable TemporalAA.
