1. How do I fix overlapping lightmap UVs

[thin mortar]

You should first check where the lightmaps overlap.

You can do this

A) in the lightmap view

B) In Scene Debug View > Overlapping UV

Here is how to do:

well I know where they overlap, but how do I fix that?

I told it to generate UV lightmaps, so now only seven objects have overlapping UVs

Its written in the article

Okay... changing to 100 has limited it to two objects with overlapping UVs... hopefully 120 would do the trick

Thats not the best way. it just fixes it somehow

Better do this aproach

increasing lightmap resolution just makes in unnecessary big

[woven gate]

I keep setting margins higher and higher, so far no progress

Okay... narrowed it down by... lowering the min lightmap resolution...

Okay, now I have no overlapping UVs, but the problem still persists, I click "generate lighting", the lighting flashes for one second, then it's dark again.

Something's just not working out, and I can't for the life of me figure what

any console errors?
Did you try using another shader?
How do your lightmaps look?

Holy shit

I added a baked GI node to the shader and it works now

Thank you for all your help
