Hi Danny, well which rendering programs are you talking about?

The 3DM importer plugin for Modo fails for this same reason, because it only tries to read render mesh data that is attached to the NURBS models and does not actually process the NURBS data itself.

But other programs like Carrara or Hypershot do process the NURBS data, and any problems they run into with direct 3DM import are just problems in their conversion of NURBS to mesh. That's not the same issue. You're usually better off not using a rendering program's direct 3DM import in these cases just because MoI's mesher has had more effort put into it than the mesher that the renderer is using.
