When sending Control rigs to MotionBuilder, the dependencies between the character elements affect which objects Maya automatically selects for the specific send operations. For example, Maya automatically selects different character elements depending on whether you are sending objects to MotionBuilder as a new scene or updating objects previously sent to MotionBuilder.
Selecting at least one element of your character's Control rig, skeleton, or mesh, and then selecting Send as New Scene automatically selects all required dependencies. This means that the Control rig, skeleton, skeleton definition, bound meshes and attached materials and textures are all included in the selection and sent to MotionBuilder.
In update operations, the Control rig, skeleton, and bound geometry are considered separate character elements and are handled independently. Selecting at least one element of the character (Control rig, skeleton and/or bound meshes) and selecting Update or Update Current Scene only selects and updates that specific element of the character. The character's other elements and dependencies are not selected or updated. If these other character dependencies are not part of the final selection, they are baked to ensure the animation result is transferred.
Selecting multiple character elements will update the selected combination. The dependencies between these character elements are as follows:
