UE4 is rendering black lines in several places. I noticed that the lines are in the corners of the lightmap.
I was able to fix some of it by changing the geometry a bit. But most of the time the line just go to another place of the static mesh.
Far away the line appears as big black dots flickering. It’s even worst in Oculus Rift, since the resolution is limited.
I’m using UE4.1.1 (It still visible in UE4.2, but my project don’t work very well in 4.2)
