Light strips along corners

[Anonymous]

Hello, I've been struggling with this issue for a long time so I decided to ask for an advice here. I can't get rid of these light strips/spots along corners and don't know what causes that. Do you know why is that? I guess it has something to do with ambient occlusion, but I don't know what exactly to change in ambient occlusion settings.[/img]

Try changing the Global Illumination preset to Interior High.
