Hi Michael,

Maya can only convert what they called 'subdiv surface' into nurbs, so in the image posted, it's the middle model. This model is a conversion from
the polygonal one. The subdiv shape allready shows some complex area in the front of the model, and this seems to be translated into the nurbs model at the end.

I have just no experience about how subdiv actually work, it seems to be way more heavier than catmull scheme. Maybe I should first learn this part to have a better control of the nurbs conversion.

I didn't remember having this kind of result with the t-spline. With the t-spline plugin, the nurbs flow was more looking like the maya subdiv one. (I'm not sure if this sentence is clear enough :P).
