We're on the same wavelength. I just got done making a heightfield as you
describe, and spent a lot of time getting it to fit exactly. There's
something Moray doesn't like about it. I saved my scene, and then worked on
the slices, and Moray crashed. When I opened the loaf scene again,
everything except the heightfield was gone, even the camera and lights. When
I opened the slice scene, the camera and lights were gone, and when I tried
to select something, Moray crashed. It's too bad, because it looked so good.
