Creating Facial Morph Controllers in CAT: A Step-by-Step Guide

Are you an animator looking to enhance your facial rigging skills using CAT in 3ds Max? Miloš Černý has shared a comprehensive tutorial on how to create controllers for facial morph targets in CAT. By following this guide, you can streamline the process, optimize your workflow, and achieve more control over your character animations.

Introduction to Facial Rigging in CAT

Facial rigging can be a daunting task for many animators due to its complexity. Miloš focuses on explaining the specific aspect of creating controllers for morph targets in CAT, avoiding the intricacies of general facial rigging. By leveraging CAT's layer system, animation management features, and other advantages, you can efficiently work on facial animations within 3ds Max.

Setting Up Morph Targets and Controllers

Barry, the character in focus, already has morph targets established for the head. Miloš skips the detailed process of creating morph targets and directly proceeds to adapt them for CAT. By adding new bones, attaching basic shapes like boxes, and manipulating them through Edit Poly modifiers, you can transform these elements into functional CAT bones.

Key Steps:

Create a new bone and a basic box.
Attach the box to the bone for CAT bone functionality.
Repeat the process for additional bones with varied shapes and dimensions.
Rename the bones to reflect their purpose (e.g., MouthOpen for controller bone).

Syncing Controllers with Morph Targets

To ensure seamless movement of the controller bones with the frame bones, link them together and utilize the Expose Transformations (ExposeTm) object. This component plays a crucial role in connecting the controller bone to specific morph targets within the Morpher modifier of the character's head mesh.

Wiring Parameters:

Utilize the ExposeTm Helper to link the controller bone to the desired morph target.
Adjust the controller's movement to influence the openness of the specified facial feature.
Enhance control by setting limits on bone movement and customizing axis parameters.

Conclusion and Future Applications

With the foundation laid for creating facial morph controllers in CAT, animators can replicate the process for additional bones to complete the facial rig. By incorporating this technique into your workflow, you can maintain a clean CAT rig structure, optimize facial animations, and elevate the quality of your character performances.

In a digital era where learning resources abound, Miloš' tutorial offers a practical, hands-on approach to mastering facial rigging within 3ds Max. Embrace the power of CAT's capabilities and unlock new possibilities in your animation projects.

Remember, practice makes perfect! Dive into the world of facial rigging with CAT and unleash your creative potential.
