The MotionBuilder interface has now been enhanced with a new color scheme and functionality.
These enhancements include:
Dark Look
To be consistent with other Autodesk applications, MotionBuilder has adopted a Dark Look UI.
Drag and Drop interactivity
You can now dock and undock UI elements around different parts of the UI by dragging and dropping their dotted edges.
Single-step interoperability
You can now send new scene data or updates to currently open scenes from MotionBuilder to Maya or 3ds Max. You can access
these new options from the File menu.
