Lights give a patterned shadow

[SirDiabo (dibo)]

In one of my projects, and in no other ones, I have this issue where all lights have a weird pattern effect.

All light sources cause this, no matter if point, rect or spot.
I already tried a bunch of stuff, changed shadow maps from virtual shadow maps to just shadow maps and vise versa.
Tried out different global illumination settings.
Set the mobility from static to stationary to movable.
Deleted all light maps and let them regenerate.
Build lighting on different scalability settings.
But nothing worked so far.

Does anyone else have this issue, or does anyone know what exactly causes it?

this looks weird. both the wall normals and the light cubemaps are breaking.

this is only in one project? then… i’d remove the shader cache in [project folder]\saved\shaders\ and regenerate them.

I couldn’t find a shaders directory in my saved folder, but I did find a shader directory in my intermediate folder? though after deleting and regenerating It’s still there. I also tried getting rid of my entire saved folder and it didn’t fix it either.

Update: after testing a lot of different things, deleting folders, switching between project and world settings and rebuilding lighting multiple times it eventually worked again. Since I tried so many things, I can’t really say what exactly fixed it.
