Add a control rig to the characterized 3ds Max biped

In the following procedure, you add a Control rig to the 3ds Max biped you characterized in the previous procedure (Characterize the 3ds Max biped) so you can animate it in MotionBuilder.

Important: To add a Control rig to the biped, you must first characterize the biped. See Characterize the 3ds Max biped.

To add a Control rig to the characterized 3ds Max biped:

Note: This procedure is a continuation of the previous procedure (Characterize the 3ds Max biped).
1. In the Character Controls window, click the Controls tab.

3. Select Biped as the Character type.

   The Create Control Rig dialog appears.

   FK/IK is the method commonly used to animate characters.

   The Control Rig is created and its effectors are shown on the biped in the Viewer window.

   

   3ds Max biped is characterized and rigged

   In the Character Controls window, the Control Rig settings are activated and include all the effectors you need to animate the Control rig.

   The Character representation is an image of a human form meant to represent the biped skeleton.

   

   Your biped is now rigged and ready to be animated.

5. In the Character Controls window toolbar ( ), click the Full Body option ( ).

   Setting the Control Rig to Full Body enables you to move the body using the entire Control rig.
