In the following procedure, you prepare the MotionBuilder scene and open the files needed to start this tutorial.

1. From the menu bar, select File > New, then select Layout > Editing (or press Ctrl-Shift-3).

   MotionBuilder displays a new 3D scene using the Editing layout. This layout displays all the windows you need for your work in this tutorial.

2. Click the Tutorials folder in the Asset browser.
3. Drag the mia_servo asset (mia_servo.fbx file) into the Viewer window, then select FBX Open > No Animation from the contextual menu that appears.

   A model named Mia (mia_servo asset) appears in the Viewer window as shown in the following figure. This character includes a “Servo arm” that is parented to the right shoulder bone and added as a Character Extension.

   

   In the Character Controls window, Mia is shown by default as the current character in the Current Character menu (A).
