I suspect you mean "location", since look_at couldn't possibly cause the
problem. That shouldn't matter...POV should only care what surfaces are
in what volumes. I put the camera inside and it renders fine. "Certain
angles" is a possibility that I can't duplicate, but I don't see any
reason for it to happen. My tests work from above, from below, from the
side, and from inside. Could you post the code you are using?

No, it matters quite a bit. Since the height field doesn't have sides,
POV can only check that the sides of the box are inside the height
field. If they are outside, they are ignored with no height field
surface to replace them.
