I have a problem that I am hoping to get some feedback on Re: soffits. I believe to be a X11 issue. In my plan, i created open rafters first on attic level with no finished ceiling, the soffits would "glow" with emission. I am a part of Chief Tutor.com so I sent .plan to him to get feedback. He took the file, put the soffit rafters on the first level and it fixed the problem on his computer. However, when i did what he instructed on my own software, the soffits would still glow in physically based render with "improve lighting quality" checked, and they are downright black when the improve lighting is not checked. He informed me it was likely an X11 issue because he was able to resolve in the newest version. Is there a work around I can do for this? I am contracted out through a small construction company and they may not be upgrading to new version; So a work around would be ideal. Thank you. See attached files for images of problem.
