Light going through edges of wall? So i started just recently learning Blender so keep that in mind.
I'm modeling a house and in Eevee rendered mode seems like light is coming in where my two walls meet.I checked for double edges, checked the normals and could not find the error. Yes my walls and floor are different objects and stacked on top of each other by eye but that could be the problem only for the bottom light intrusion. Ill add pictures so you better understand.

Any help welcome AF! Thank you!
Select the light you have -&gt; properties editor-&gt;enable shadows and enable contact shadows in it.
It is only necessary for cycles render engine
