OpenFX is an Open-Source 3D modeling, animation and rendering suite created by Dr. Stuart Ferguson. He made the decision to release the source code to the public in the middle of 1999, and the product formerly named SoftF/X was renamed to OpenFX.
It has now been released under the terms of the GNU General Public Licence.Yes I use it as a modeler, but it also contains a top notch animation feature and is a complete suite of tools.
