Lighting (or lack thereof) - Am I doing something wrong?

I've seen quite a few threads about lighting and its problems and whatnot, but I have the impression the images I see area always so much better than how things look in my game...

Take this hangar for example:



It's just so dark. Both in and out. And it doesn't matter how many lights I put, they seem to create more shadowy areas than properly emit light... Which only makes it look even worse.

Is there any setting maybe? Like in advanced settings,...
