First thing first. I think the level was corrupted. I created a new one and recreated it. Mo I have actual builds and some results. Also the problem I had earlier was related to incorrect light maps. Now I inspected all UVs, set up resolution.
but I am getting now some weird results or artefacts from lights.
The ceiling lights are in a blueprint and scattered across the scene but in some places, results just do not look correct.
From my testing, I know that the problem is with the spotlight. I put an extra cube on the wall to test if is it with the wall or with the light and as the shadow continues across the box I think it is the light.
The main source of light in the level is those ceiling lights.
