I have done this with the pnurbs plug-in with the eve model awhile back and I still have it. The object is about 4.5 megs in size. And IS very hard on memory usage. A interesting side note, I also converted alot of morph targets to hi res using the same p-nurbs procedure. This will work as long as long as the morph was created for the eve model. The number of vertices and subdivisions created on the morph object will be the same as the eve object and will work fine. So the morph objects are really no problem. However remember that the morph targets are larger and take up additional memory also.
