About shadows and lightings

Hi, this is my first time rendering a simple scene in unreal engine. And I just want to ask how can I fix this shadow on my assets.

Also, I have a problem on the side of my wall. I have this white light that penetrates the wall and I don’t know how to remove it.

Thank you in advance for your help.

You should ensure that your meshes are fitting tightly enough. This light bleeding is most likely happening because you have little bit of floor protruding past the wall and receiving light there, and lightmapper interpolates its inwards into the room
