What you suggest is essentially what I ended up doing by hand
in an example that I worked up. I've got lighting to work
with materials but texgen is slightly (but noticably) off so
edges are visible. Straight textures worked well.
It sounds like it would be best to just tell people that they
will need a machine with hardware multi-sampling in order to
smooth generic models.
Thank you for your reply.
