The Autodesk® FBX® technology is one of the most widely used and supported platform-independent 3D data interchange solutions around. Universal 3D asset exchange via Autodesk FBX helps to remove data compatibility barriers and gives you the freedom to build an efficient pipeline for your projects.
Autodesk FBX fosters interoperability between several Autodesk products. The MotionBuilder software product supports FBX natively, while the Autodesk Maya and Autodesk 3ds Max software products include FBX plug-ins. In addition, the Autodesk® Softimage® software product can read and write FBX through the Autodesk® Crosswalk software initiative. Autodesk ® Mudbox ™ 2010 software is the first Mudbox release to support FBX, streamlining common workflows between Mudbox, Maya, 3ds Max, and MotionBuilder.
