Same objects, different lighting

Few abstract buildings with one material, all are Static. Directional light is Stationary. One building is imported mesh, others are UE basic shapes. After building light: mesh has dark shadows, basic shapes - light shadows. Why?

If mesh is Stationary, is looks lighter than Static, but anyway darker than basic shape.
I break my mind trying to fix that ((

…and more, it is problem with textures in imported mesh. Texture is applying, but looks like color. I dont understand, maybe wrong UV? But UV generates during mesh import.

please post screenshots of the material and the mesh UVs.

I’m dumb. The problem was in the absence of UV map. After map was generated, everything became fine - both lighting and textures.

that would certainly cause the issue. please mark this as answered if you don’t have any more issues.
