Light Bleed

Bulldog3dz

Hello all,

I'm new to lighting and I'm having an issue with light bleeding through to the interior of this room. 
Does anyone know what causes this? I thought it might be an issue with the thickness of the walls, but I gave them some thickness and didn't see any differences.

Any help would be appreciate, thanks!

Check the lumen debug views under lit, could also try putting light blocking boxes inside the walls.
