ok, I will send you the scene. Regarding the issue of geometry not displaying when enclosed in groups and subgroups, if I find an earlier version where I haven't broken everything down inside. As for exposure, there may be aspects I don't fully understand, but generally I have this problem: like in photography, if you take an interior shot focused on objects, your window will be white, with saturated light. If you focus on the window, the outside landscape, a digital camera will make the interior extremely dark so you can see the trees and the garden. Just like the human eye. Except our eyes are very fast and correct in microseconds, which allows us to see both the exterior and the interior so clearly. That's light sensitivity. If there's a way...
