Thanks. Added to known bugs.

I think I'll move that into the "not a bug" box, unless anyone has
serious objections.

I knew that, the question is whether the code should behave that way or
not.

I can duplicate this (although the quick version that I wrote now runs
to completion). The point at which the quick version collapsed into
blankness has varied from beta to beta, and now manages to go all the
way through. The original scene file posted by Warp still fails when
rendered with the specified size and antialliassing.

The question is whether this is a bug, or whether isosurfaces that use
crackle can legitimately be expected to disappear.

Thanks. I'll add that to known bugs.
