Lighting and shadow problem.

Hi everyone ;
Firstly sorry for my bad english.

There are shading problems on the walls and floor that I created with the geometry box.
I tried using geometry boxes as static, but the problem is not solved.
Light infiltrations, leaks etc. I have tried the lightmap resolation 32,64,128,512 and 1024 but I didn’t get the result.
