Hi,
I’ve seen this problem since the start when I created the faces, sometimes those lines appear, and I dont know why.
I’ve cleared the normals data, reduced the auto smooth to 20 deg but the problem is still here.
Here’s the link to my actual work :

I’ll check now the other issue that Martin send above to see if I can gather some other solutions to this problem.
Anyway, thanks for helping me, great community on this site.
