Adverse light conditions on textures

Hello!
I have a problem for which I could not find a help anywhere on the Internet.
My problem is that, despite the direction of the light, the shadow and bright sides of the objects are in the wrong direction on some objects.
Can anyone explain what could be wrong? Thanks!

Hi! You Scalability level is low. Try to increase it. If your machine can’t handle it, try to bake the lighting. If you bake the light, the lighting will much accurate, and cost les gpu time.

Thank, but I’ve already looked at it, it’s less noticeable, but it’s still visible. I almost forgot that the other strange thing is that the sunlight goes through the walls. Otherwise, this is what it looks like in epic quality.
