I am relatively new to using UE 4, so I hope this issue has not been discussed before. I used search on the answerhub and in google, but could not find any solution to my problem.
I have a simple szene-setup with a floor, a room and a roof. The lighting works pretty well on every asset except for the roof, althoug it has a veeeeeeeery simple geometry. It is little more detailied by now, because I thought it might be caused by not having enough polys or something, but that did not work either.
The result looks like on every quad-edge there seems to be an error (looks like a shadow). I used a customized lighting UV, just so that everything could be computed in the best way. You can see both screenshots attached. I don’t know what I do wrong, because I did nothing different than when importing the floor and the room and these two assets do not behave like the roof.
