I remember reading somewhere in the ~ 40,000 messages here or
in an isosurface tute that:  noise and bump always "remove" material
from the surface. However, if you apply it using negative values, it
will "add" and raise the surface.  Could it be that the gap you are
seeing is the missing material?  Would neg values raise the level
above your box or at least to it's bounds?

Sorry Ken for emailing you for help . . . I think I finally figured out
the problem. But of course I won't know until I see this make the post.

Thanks all - just discovered these newz groups. I'm jazzed !!!   TS
