I saw some pictures of a house with tray ceilings, and now I've been trying to build one myself. I found two video tutorials for it, both from 2010. The tutorials made the process seem pretty straightforward--building a tray ceiling is a fairly simple application of ConstrainFloorElevation, kind of like building a split level, which I've done before.
The process seems to work perfectly for me, except for one fairly major problem. My result always looks like it ought to, from the outside of the room. But from the inside, if I zoom the camera in to the bottom of the room and then tip it upward to view the ceiling, where the top level of the tray ceiling should be is just transparent--nothing. I can see the sky.
I wonder if the problem is that the tutorials I found are quite old. Does anybody perhaps have experience with building tray ceilings? Have you seen this problem before, with the top level just being transparent when viewed from inside?
I'm stumped! Thanks in advance for any help.
