Grouping and 3D entities

Ok, here's an issue I ran into regarding importing a model that is grouped in MAYA.
When I animate the object on a curve, VIRTOOLS is looking for a 3D entity, not a group. My model has three parts to it, grouped and parented in MAYA. I'm hoping to resolve this because the only other solution seems to be creating one model in MAYA with merged vertices, etc...






As you can see, Virtools imported my 3D Entity in pieces - they need to be grouped
in order to be animated as a whole....
