SteveMacc,

Yeah, getting a meshed model that can be sub-d is tricky. The problem with leaving it as plain polygons is that while the vertex normals will smooth the look of the surfaces, you can see the polygonal shape on the edges sometimes if you view them from the right angle. Right now I'm experimenting with getting meshes from MOI into MODO. Hopefully if I build the model right in MOI I can avoid having to sub-d, but I'm not sure that will always be possible.

Right now this model looks good when I render it whether I sub-d it or not, so I'm inclined not to.
