This seems to be just another max_gradient affair. If you set it to 160 (80
was not enough) the Iso will show up. My testrender is now at 80% and
everything seems to be okay.
If you narrow the contained_by-object, the samples Pov takes with a given
max_gradient and accuracy will be not that far apart and this will lead to a
more accurate isosurface. For this it's always a good idea to bound the iso
as narrow as possible.
