Before sending your HumanIK rig to MotionBuilder, make sure that you have set your Maya project and saved the scene you want to use in MotionBuilder to the currently set project.

Sending a new scene to MotionBuilder

1. In the Outliner, viewport, or Character Controls, select at least one character element (a bound mesh, joints of the character's skeleton, or an effector of the HumanIK rig) and Maya objects you want to send to MotionBuilder.

   See Selecting HumanIK character data.

2. Select File > Send to MotionBuilder > Send as New Scene.
   NoteIf Send to MotionBuilder does not appear in the File menu, you may need to reload the OneClick plug-in. See Load or unload Maya plug-ins.

   MotionBuilder starts and opens the objects sent from Maya. Maya and MotionBuilder are now connected as indicated in both application status bars.

   
3. Using MotionBuilder, animate or apply motion capture data to your HumanIK character rig.
4. In MotionBuilder, select File > Send to Maya > Update Current Scene to send the rig to Maya. Maya loads the animated rig.

   You can also click Update in the MotionBuilder status bar to send the scene back to Maya.

   

   You can make changes to the objects in a scene and/or add new ones, then update the other application by selecting them and clicking the Update button.
