Yep...absolutely free. It appears that MS is pulling the plug on publishing for Caligari.
3D Modeling Software - trueSpace
While not the most popular editor in existence you still cannot beat this freebie. All training videos are free and have been packaged into a nice zip file. Don't forget to visit the third party sites as there is some great free stuff there as well.
I figured this was appropriate enough for GD and too important to throw into the huge freebie links post we have going.
Many thanks, Caligari.
