Weird light after render

[Wizzardius]

Hi guys. I am completely new in Unreal Engine, this is my first piece of animation in here (before i was working in Blender). Any ideas how to get rid of all this glittery things in render? Without anti-aliasing it seems ok, but reflections are not so high quality i think.

I am using unreal engine 5.

Try making your walls ever so slightly more rough and see if rendering this again you still have the artifacts.

Also try turning up the quality on lumen reflections post processing
