Just got an email from caligari. It seems that they have finally released a demo version of gameSpace.
"A free trial copy of gameSpace1.1 is now available
for download. This is fully functional, including the
ability to save and export to game formats, so you can
start using gameSpace right away!
Designed to be accessible for independent game
developers (who are often on a tight budget!),
gameSpace is based on the latest version
of award winning trueSpace. Extra modeling tools, and
compatibility with game formats, has been added, to bring the
functionality and ease of use of trueSpace to the gaming
community and also to those interested in a world class
modeler!"
