Eevee

hello everyone. is there any tutorial about how eevee works (especially in interior)? I completally don’t know how it works. When i put sun as a light source i get this result.

Hi. Share the .blend file.
Anyway there are some tutorials on YouTube explaining basic issues, and also some documentation:
