Lightmapping Shadowbleeding

Unity Engine
1

hey, I have two meshes (walls) on top of each other, perfectly lined up and somehow I still get a weird shadow bleeding (dark line along the edge) between of the two meshes. Even in the corner I get a lttle dark line along the vertical axis eventhough this is just one mesh. All meshes uses lightmaps via unity (generated Lightmaps in import settings)

I also get weird shadows at the windows:

and from inside, the entire frame gets messed up (supposed to be white):

Any ideas?

Check the sending and receiving shadows settings in the editor window. Play around with dynamic and baked lighting too but don’t forget to clear the lighting cache when necessary. Unfortunately I had issues like this too and it was a case of trial and error to fix it.
