Dale,
The spline modeler is a great lathing tool but if you want to tug
vertexes around, convert the spline model to a low resolution vertex
model and smooth it using the subdivision surface option.
There are some tricks involved.
First, use a very low fidelity setting in the spline modeler, as low
as 5 or 10 percent. By switching to wireframe view you should be
able to preview the simplification in the spline modeler. You want a
very blocky mesh that still retains the overall shape. Omit the
pouring lip for now. Name the original and duplicate.
Then convert the duplicate to a vertex model and delete all the
diagonals, giving you a low poly quad mesh of the pitcher. (This is
tedious, so put on some good music.) Name this and duplicate. (The
point of duplication is to preserve earlier versions.)
With the duplicate vertex mesh, switch on smoothing and watch the
effect of pulling a rim vertex out and down to create the pouring
lip. Name this and duplicate.
With the second duplicate, which has the pouring lip, first, name
the mesh in the vertex modeler, then create a thickness and name the
new surface, too. Create separate texture domains for the inside and
outside surfaces.
When the resulting surfaces are both smoothed, you should have a
very credible pouring pitcher. With a layer list of parametric
shaders you can shade the outside surface to give it condensation
and drip texture, and shade the whole model to give it refraction
(and fresnel effects if you have Ztools).
