Loft - only working to try and figure out this feature. Created a square house, added second level, placed stairs, which states right level etc. using the open below below feature for half the upstairs room and when I go into regular camera view I see the sky and ground on the open below sides. All other views are normal. I have been watching videos and reading for a week and even though I feel I am following videos etc, nothing works. I am playing outside of my house design just to try and figure out this feature.
I would appreciate it any help as I feel it must be something simple I am missing.
