How to enable default rooms to use lighting?

[Synfinity]

Someone told me how to do this before, but I can't remember how. In some rooms the scenery does not reflect light source changes from the menu. There was an adjustment you could make, but I can't remember.

NOT H5 lighting, but the built in lighting from the context menu.

Did you checked the Optman.exe?

I assume you already checked the customizer special settings?

2nd example is what I'm talking about. You adjust those and it affects the lighting on the models themselves, but not the rooms. Some rooms it does, some it doesn't. Like the Dome of Pain, it doesn't register those lighting changes. I think it's a setting within each room's, .bs files but for the life of me I can't find it now or remember it. I know I adjusted it successfully before, but my old PC died and took the HDD with it, so I am working with a fresh install and trying to get settings back to where I had them.
