It’s surelly nanite’s tessellation trouble, im getting these black dots and lines on my render while in editor everything is allright, tried turning off screen percentege in console variables – no fix, tried every setting in MRQ – no fix, only turning off nanite on the mesh fixes this trouble, but it’s not a solution…
So, it seems not nanite/tessellation problem, it’s meshe’s problem – replacing that mesh i have as the floor with completely another mesh (standart cube) resolved the issue.
Unfortunatelly, i didn’t manage to find out what exactly in that mesh caused this problem…
It’s not a solution, so i won’t close the ticket, cause it might happen with other custom meshes, we need a better way…
ps: If anyone wants to help i can share this mesh via any social media to help me find out what’s wrong with it)
