Can't make baked lightning work, getting errors, what am I doing wrong?

Ok: 1. I have a room as a mesh imported as .fbx from the Blender. 2. I have some point lights in the room. 3. I've checked my mesh on my scene as "static". 4. In mesh-import settings I've chosen: "Normals - calculate", "Gerenate Lightmap UVs". I tried toimport materials with the model or switch this off. 5. I have no materials applied on the mesh (I tried with the ones that has material on it - nothing changes). 6. I've chosen "Baked" for point-lights.

So: When I try to bake the lightning I gives me some errors and bakes nothing at all.
But when I change Lightmapper from "Enlighten" to "Progressive" it works, but I don't want that experimental feature, just checking.

Errors it gives: 1. Mesh doesn't have UVs suitable for lightmapping. Consider enabling "Generate Lightmap UVs" in the model importer. 2. Mesh doesn't have albedo UVs. Please create them in your modelling package. So what am I doing wrong with Unity? I just want simple lightning to be baked. Seriously, it makes me feel sad. Unity ver. 2017.2.0f3. 64-bit.
