Truespace 3.2 since it's free

I don't really do much modelling, though... so I can't pass judgement on how good or bad it is compared to other programs which I also don't use.

If you do download it, be warned: you'll probably be inundated with Caligari spams each week wanting you to buy the latest version. went ahead and set up a filter in her email to toss them into the trash when they arrive

But hey, it's another freebie program that you can add to your collection. :o)
