Black spots shows up on static mesh
I'm getting those weird black spots on my level. I even set the lightmap resolution to 1024, but still no luck

Couple of questions and some suggestions: First, these artifacts tend to show up in the High to Production quality lighting bakes. The reason for it is that they're a bit more high fidelity, and therefore you need to have quality lightmaps otherwise you'll get mixed results. So, are you running a Production lighting quality or Preview?
Is your level a single mesh? If that's the case then I'm lead to believe that your lightmap resolution, even at 1024 is still too low. Looking at your UV map, there is a ton of geometry that you're squeezing into 1K of memory. Lots of geometry is fine, so long as the mesh is smaller, you won't see anything like this happen. I would recommend splitting up this mesh into different static meshes with their own lightmaps and texture spaces. Though it's true going full modular causes different problems, if you split this up into 3 meshes, one for your floor, your ceiling and walls and adjust the lightmap resolution for each, I expect you'll get much better results.
