In my experience most of the polygon reduction tools end up
distorting the model when you start getting to the kind of
reduction levels your talking about! So depending on your
model you may be better off rebuilding.
One of our guys just finished doing this for a client. The database
he worked with was building used for a walk through! A lot of the
work was replacing parts of the model with lower polygonal objects.
He used Multigen because of it's compatibility with performer.
My wife uses Maya to model ocean going vessels then exports them
to inventor using alias. Since they are used in a simulator, she
has to be conscious of the polygon count and builds them accordingly!
So what kind of object
