There is the main gmax download...
I'll be putting up the following resources shortly:
1) a file on xelerus containing Gmax Rendersuite w/ YAGmax, and a blank scene set up specifically for rendering ships/stations in transcendence
http://xelerus.de/index.php?s=mod&id=505
2) a tutorial on how to use Gmax to render a very simple ship.

-enjoy!
