Hi Burr, just another bit of info on Network.

When I say it needs to make a "regular" UV grid what I mean is that every U curve crosses every V curve.

So for instance something like this is not going to work right:




That does not form a single complete grid, for example note that this pair of curves (one from the U direction and the other from the V direction) are not crossing each other:




In a NURBS surface you can't have just one single control point in the corner missing like that, a NURBS surface is made up of the same number of points in every row or column. The same kind of thing applies to Network as well.
