Lighting problems (incorrect shadows)
Please look at the pictures, the shadow and light is somehow not correct. I dont know why this happens.
The scene has a lightmass importance volume covering the whole level. The walls and floor are all static meshes, setting lighting build quality from low to production also doesnt change this problem.
My question is what could be wrong or what can i possibly do against this?

Increase the Lightmap Resolution of your Floor Mesh. Go into the Lightmap Resolution Viewport (Upper Left Corner) and adjust the Lightmap Resolution until your Floor appears green. (Blue = Too Low, Red = Too High, Green = Okay)

2048 is very high!! ...although maybe your plane is very big... Try lower value /even though in the editor it shows blue you might get a better build time and good enough quality/! One huge lightmap slows the build time by a lot! ...using more but smaller ones is faster! ...you could also break up the main plane into smaller /modular/ pieces with smaller lightmaps! And you should also check out cascade shadows!! In your case you could get away with a lower lightmap resolution mixing with cascade shadows!! Also recommend to go through this site: [https://wiki.unrealengine.com/LightingTroubleshootingGuide] [https://wiki.unrealengine.com/LightingTroubleshootingGuide#Directional_Light_ONLY:_Cascaded_Shadow_Maps_Settings:]
Good luck! :)
