Adrian,
That's exactly correct. If there is no material associated with a face
then there is no Shape3D created. Essentially if the shape has no color
it's "invisible" and thus we don't import it. We don't import geometry
that has no information for displaying it ({laugh} It's a feature not a
bug!).
