John, you bring up an important point. One of my goals with the OMR was to
be able to recreate them in scenes, but doing it completely by the books
would restrict that. We should rethink this a little, but not enough to
lose track and take a week on it. What would be the best filenaming system
within subdirectories that would allow for rotating and moving parts?
I know when I make my models - such as the TD-08 at
http://www.zacktron.com/alliance/mil/space/td-08.html
I make the parts so they can rotate best. The gun turrets in the front of
the thruster pods consist of a turntable bottom and a hinge top together,
and then the gun assembly with the hinge bottom. This way I can rotate the
parts to get the gun position I desire.

Good idea on making the MPD - we still use subdirectories but do a little
MPD hand editing.

Correct. I believe there needs to be some revision and modification to the
way our MPD utilities work.
