Unsupported Undo functions

An undo/redo function has been created for almost every action in MotionBuilder.

Press Ctrl-Z to undo any of the following:

• Editing, duplicating, renaming, selecting, parenting, and animating (including transformation and key animation,) of objects.
• Applying assets to objects, for example shaders or textures
• Changing properties (even in tools that do not support the Undo function, such as the Dynamic editor)
• Constraints (except Expressions constraints)
• FCurve animation
• Shader manager
• Relations constraints
• Applying poses to characters

The following tools and actions have no Undo function:

• Characterization and Actor setup, including modification to animation using the Dynamic editor (except edits made to FCurves)
• Creating Control rigs
• Deleting a Character Extension
• Editing groups and sets
• Adding custom properties
• Expressions constraints
• Skin tool
• Face tool
• Audio tool
• Video tool
• Midi tool
• Voice device

If an action cannot be undone, a dialog box appears to warn you.
