Black lines appear on meshes at the corners of the lightmap
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) Radeon HD 4990
Hey fabianoberlim and DarKris3 -
So after much experimentation and discussions here, we have narrowed down the issue to one related to a video card driver. We are in the process of setting up a test with a Radeon card and drivers. I will let you know as soon as I have the results.
I was finally able to reproduce the marching black ant lines on an Nvidia card with the Beta driver installed but switching down to the WHQL release driver clears the issue.
Thank you both for your help and I will keep you informed.
