When I take a Floor Camera view from a room below an Open Below area, I see sky instead of my upper floor. How can I resolve this?
The Floor Camera tool creates views of the current floor only. The ceiling and anything above it is not generated, and neither is anything below the floor.
Instead of using the Floor Camera tool, use the Full Camera tool, which does not have the F on the icon, to create multi-floor views of the 3D model.
The Full Camera tool can be used to create both interior and exterior perspectives and is ideal for displaying cathedral ceilings, roofs, lofts, stairwell openings, and other variation in floor and ceiling levels.
