Updates to USD workflows
MotionBuilder 2026 extends USD-based workflows, USD support having been introduced last year in MotionBuilder 2025. When loading a USD stage file, the animation contained in the file is now retained, and will be rendered. A new animatable frame offset property in the Python API makes it possible to retime or time warp the motion. There is also a new button in the UI to reload USD stage proxies, and a corresponding property in the API.
Other quality-of-life improvements
Workflow improvements include a new shortcut key to force-select previously unselectable objects, and support for extended function keys – [F13] and beyond – as keyboard modifiers. There is also a new SDK property to control whether HUDs are exported in FBX files, and some API properties have been renamed for clarity.

Enhanced icons and scaling support
MotionBuilder 2026.1 introduces new, high-resolution icons to enhance the user experience and support better scaling on high-DPI displays. This update ensures that icons are crisp, clear, and easy to recognize regardless of your screen resolution or size.

Configurable default scene frame rate
The default scene frame rate to use when starting MotionBuilder, or when creating a new scene, is now configurable in Preferences under the new Transport Controls section, streamlining your workflow and improving precision in animations.

New connection styles and grid snapping for Relations constraints

Connection styles
We added four new connection styles to the Relations constraints' graph interface. These connection styles are: Bezier, Straight, Corner, S-Shape, and contribute to a more efficient, flexible, and user-friendly experience when working with the Relations constraints' graph in MotionBuilder.
