Preamble: trueSpace is a wonderful rendering environment and a confusing modeling environment, so I'll spend more time on rendering than modeling in this series. TrueSpace uses the left, the right, and both mouse buttons depressed, unlike a lot of other programs: we'll get to this a little later.

To get going, download trueSpace from Caligari's server (click on this dot) Last we looked, they were offering version 3.2 for free. If they've changed their minds, the steps to follow are compatible with trial, later versions you can download from there.
