Bleeding light .. please help

Hi all. please help how to resolve this bleeding light in the corner between wall and ceiling. please see the attached photo. anyone has experience this situation?

Thanks in advance.

I have two possible solutions:

  1. try rendering at higher quality

  2. try making your walls thick

  1. And ceiling - light leaks like that are normally caused by making a wall and ceiling from a surface skin rather than from a solid section: give them about 300 thickness and you shouldn’t have a problem… unless it’s caused by something else.

thanks it works. it needs to be thick and you have to intersect all corners and edges.

thanks again guys.
