Updating a Control rig to remain compatible with older versions

 
 
 

The MotionBuilder 5.5 Limits property has been removed from the User Interface (UI) in the MotionBuilder 2010 version. As a result, a warning message now appears when you load MotionBuilder scenes that contain a character or characters that use the “Enable MB 5.5 Limits” or “Use MB 5.5 Axis Orientations” property options.

If you want your Control rig that uses the MotionBuilder 5.5 Limits property options to remain compatible with MotionBuilder scene files created in MotionBuilder versions post version 7.5 Extension 2, you need to update your Control rig.

To update a Control rig that uses MotionBuilder 5.5 Limits:

  1. Load in a version of MotionBuilder prior version 2009 your file containing the character that uses the “Enable MB 5.5 Limits” property.
  2. Select all the skeleton's bones and open the Properties window.
  3. Select the All (Type) view in the View menu to display all available properties.
  4. Expand Degrees of Freedom > Rotation > Post Rotation and disable the “Enable MB5.5 Limits” option.

    Once you disable the “Enable MB5.5 Limits” option, you are ready to update the rig.

  5. If there is no animation, follow the instructions in steps, 6, 7, and 8. If there is animation, proceed to step 9.
  6. Put the character in a T-stance.
  7. In the Navigator scene browser, delete the character constraint.
  8. From the Asset Browser’s Templates folder, drag and drop a new Character constraint on your character's bones in the Viewer window and choose Characterize.
  9. If there is animation, plot the animation onto the skeleton.
  10. In the Character Controls window, put the character in a t-stance.
  11. In the Navigator scene browser, delete the character constraint.
  12. From the Asset Browser’s Templates folder, drag and drop a new Character constraint on your character's bones in the Viewer window and choose Characterize.
  13. Scrub the timeline to verify the animation is still present.
  14. Plot animation to a new rig.
