Here is a space freighter designed with Babylon 5 in mind.  The file structure for all the
necessary files is as follows:
Newtek\(objects)(images)(scenes)\Babylon5\freighter

There are envelopes in the setup scene file for strobe lights, and the rotating living ring 
section.  To animate the 6 maneuvering thruster flames, just scale the appropriate flame in 
the Z axis, and use a dissolve envelope as necessary.  Use envelopes for the thruster light 
and lens flare accordingly.  The whole assembly is parented to a null object to avoid 
gimbal lock when moving the freighter around.  Have fun.
If you have any questions, email me at mstets19@wavenet.com

You may use this object any way you see fit as long as I get acknowledgement for it's
creation.
