Black line over some models

[Kyrylo]

Hi, guys! I’m pretty sure that a lot of people met this problem, and funny that I can’t find the problem-solving. So the problem is, how you can see on the image, is that over models I have these ‘black lines’. There are no errors in the console, but a few times I saw a message about a broken uv-map. Thank you unreal, why always me. Do you know how to fix it?)

I will appreciate any of your advice!
Thank you.

Maybe some Z - fighting? I don’t know. Does this happen in play(on your computer)? Just enable the flying around for a second and see. Or building the lighting, perhaps. I can see that it says LIGHTING NEEDS TO BE REBUILD.
