Im close to finishing my level of my first game project. I’m having visual issues. I get light bleeding through the walls, The walls look very grainy, and there is light pops, flickering, and bright flashes often walking through the level. It is a night time level of a school building. please help if you can, thanks!!
Walls might be too thin, causing light bleed. Try increasing their thickness.
Flickering might be from occlusion culling not seeing an object in time, you can try increasing the mesh’s bounds and see if that helps.

So few workaround:
For light leak between walls, wall thickness should as least be 10cm. (or you can place a big dummy block over a house for example to block the light leak but that doesnt always work)
To reduce lumen artefacts like grainy and flickering, you can increase the lumen quality(from your global post processing) at the cost of higher gpu resources:
- set to Hardware Ray Tracing, this should drastically improve quality
- set Lumen Quality to 2.0 from Post Processing Volume
- latest unreal engine version did provide some improvement on reducing artefacts as well
