hmmm. I meant that your objects (and materials) seem completely unlit, except that they do have shadows like you’re showing in your new screenshots. That building looks like you photoshopped an AutoCAD drawing into the Kite demo. That’s not an insult, I’m just genuinely fascinated by the unintentional art direction 
So I would look at your materials and make sure there’s no funny business going on. Try adding some starter content or Kite demo materials onto your objects and see if they get lit differently.
I believe the biggest problem might be the sun light that is set up for dynamic and distance field lighting and all that. You should disable it and create a new default light source to troubleshoot.
