Getting strange dark artifacts
Hello. I'm having some trouble with rendering of a PBR Brick material. My game is very dark, and the only light source is a flashlight (which is a spot light). The problem is that with some certain angles, I got really ugly artifacts on the wall, like in the following photo:

The issue lies with your normal map in your brick material. Open your normal map texture and follow these 2 steps:
Set the Texture Group to WorldNormalMap > Set the Compression settings to Normalmap. (I will add a screenshot highlighting these areas)
This happened because when you imported your normal map Unreal didn't recognize it as a normal map and gave it default compression settings. Just be aware while importing normal maps and make sure they get the proper settings!
I hope this helps.
