I am trying to bake a scene with these settings:

and getting artifacts like these:

I did try to solve it for quite a while, checked this whole documentation, tried higher number of samples, resolution, etc. but nothing. I made this whole model in Blender and imported as fbx, tried both Calculated and Manual margin methods, nothing worked.

I want to have black glossy material, with lights, so that it bounces light. I like how it looks in realtime, but it is, of course, very inefficient. I also get the following message:

This GameObject has overlapping UVs. Please adjust Mesh Importer settings or increase chart padding in your modeling package.

I added another UVMap to that object, and made Smart UV Project, but it didn't work (asked ChatGPT). I know there is many things to fix, but have no idea, how. Any ideas?
