Broken shadows

Sorry for my eng.

Eh i have problem with shadows. Everything is okay before i build the shadows…

I sent this mesh to my friend and everything was okay but he’s working on an older version of the Unreal… Idk have You an idea?
Oh and autosave… screen:

Help :<

Probably just a low lightmap resolution on the floor mesh. Try 512 or 1024 and rebuilt.

Omg that was so obvious… Thanks buddy! :smiley:
