Blender never behaved for me after multiple downloads and installs, the commands never worked. So I just stuck with trueSpace and suddenly, one morning, the Gencore VF-21 'Harpy' Space Superiority fighter popped out, with thrusters and shields. The rest is history. A week later, the Gencore VF-22 'Phoenix' advanced interceptor/space superiority fighter followed, and shortly after that, the Predator class Destroyer - my first warship.
All created in trueSpace 5.1 which I love to bits!
Although I COULD use Maya I guess, as I got a copy of the PLE with UT2003.....
