Improper Lighting when a light is behind a wall

This image mostly explains what is happening.


I have rebuilded the lighting several times, even on the ‘production’ setting.
Any ideas?

Edit: this image better displays my problem.


What exactly are you referencing to as improper lighting? I don’t think I can see anything strange on the screenshot.

looks like you may have to reduce your attenuation radius on the light maybe? post a pic of the scene in editor.

Sorry. I added another image that shows my problem better.
There is no seams in the walls, yet the lamp’s light still is being rendered on the walls.

Reducing the attenuation radius fixed it. Thanks bro.
