TrueSpace

This is the full working version--nothing removed or crippled, no time limits or watermarks. Features include: Powerful point editing, smoothing, sweeping, and deformation tools; amazing metaballs and plastiform tools to create organic shapes; multiple spot, local, and infinite lights; full physics simulation engine; bones, skinning, and inverse kinematics for character animation.

A large number of file import and export formats add to the flexibility and compatibility with other programs. Output formats include rendered stills, animation, or VRML. A very active community provides support and interaction. Large selections of 3rd party plug-ins provide extra capabilities.
