When drawing polys on the Reality Engine using concave(TRUE)
I get a few polys that appear to be missed out. (Ie. some
convex polys become invisible) The polys _are_ visible on
PI's and Indigo's though so the problem appears to be with
the RE.

If I turn concave polys off, obviously the RE (and other machines)
screws up the truly concave polys. Anyone know of a bug that
would cause this and how to overcome it? (apart from removing the
concave polys)
