Autodesk MotionBuilder

MotionBuilder is the industry standard for high-volume 3D character animation and real-time motion capture processing.

Production houses like Ubisoft and Industrial Light & Magic rely on MotionBuilder to handle massive data sets with low-latency performance. It excels at retargeting motion capture data onto complex skeletons and provides a non-linear editing environment for refining performances. The software supports live device integration (including OptiTrack and Vicon systems) and utilizes a robust C++ API and Python scripting for pipeline automation. Its real-time architecture allows animators to visualize character interactions and physics simulations instantly, cutting down iteration cycles for AAA games and cinematic features.
