Strange shadow rendering

I’ve experienced a strange bug with lighting, when i build the lights or build all levels shadows noticeably deteriorate in quality, becoming incoherent and oddly shaped. Has anyone had the same problems as me? I’ve been using Unreal Engine 5.1 for a month maybe i made something wrong

First off, do you need static lighting? If not, use moveable.

If you do, then you need to increase the lightmap density of the floor mesh :slight_smile:
