Are you sure you’ve built lighting? I’m seeing that red error in every screenshot warning you that objects are unbuilt. You need to have static or stationary lights, a lightmass importance volume, and then you Build lighting. In the World Settings, make sure you have the bounces set to a high number, the indirect lighting quality set to a higher number, etc. It looks like most of your lighting comes from dynamic or otherwise direct lighting that can’t provide the soft shadows and global illumination that a lightmass build can offer.
