You can use Send to commands to exchange data between MotionBuilder and Maya or MotionBuilder and 3ds Max.
The Send to commands establish a connection between MotionBuilder and the target applications (Maya and 3ds Max). While the connection is established, selecting the Send a New Scene, Update Current Scene, or Add to Current scene command enables the applications to share data. To break the connection, close the scene in one of the applications, exit one of the applications, or use a Send to command to exchange data with a different target application.
Each application can be connected to only one other application at a time. Established connections between MotionBuilder and the target applications are indicated in the application status bars.
The Send to commands are located in the File menu of the MotionBuilder main menu bar. If the target application is not installed on your system, choices on the submenu are not available.
Objects exchanged between MotionBuilder and the target application are matched by name. If you change the name of an object in MotionBuilder, it will not be included when you update the scene unless you add it explicitly, and the object with the old name in the target application will not be automatically updated or deleted. Objects are sent from MotionBuilder to the target applications using the FBX format. Any application features that are not supported by FBX are not transferred between applications.
If you want to send a user-defined camera to a target application, you must make this camera the current view or select the camera in addition to the scene objects that you send.
When sending objects as a new scene, the timeline duration and rate in the target application will be adjusted to the timeline duration and rate from the source application.
