INTRODUCTION TO RIGGING

Character Rigs represent a unique, stylized character which can be animated. Different from a 3D sculpt, a rig is a model prepared and ready for animation. There are three main types of rigs with differing capabilities:

  • FK Rigs – Forward-Kinematic rig. Bones & skin that move together. Forms the basis for other rig types.
  • IK Rigs – Inverse-Kinematic rig. Joints move based on controllers. Commonly used for keyframe animation
  • MC Rigs – Motion-Capture rig. Joints move based on motion data. Commonly used for capture-based animation

We provide several completed MC Rigs ready for animation with data on this website.
Below are details on how to build your own FK, IK and MC rigs.

RIGGING TUTORIALS – FORWARD-KINEMATIC (FK)

After modeling a character in 3D, the FK Rig is the first step in making a useful rig which contains bones & skin. The following FK tutorials are provided to help you quickly create new characters. Historically it was necessary to do joint and bone placement manually, a tedious process (Fig 1b above). Now those steps can be automated with Auto Rig tools. This lets the character creator focus on sculpting (Fig 1a), painting (Fig 1c) and parts (Fig 1d).

RIGGING TUTORIALS – MOTION-CAPTURE (MC)


Figure. Overview of motion capture based character animation using a Maya workflow. A few of these steps, e.g. sculpting, painting and animation, are suitable for classroom projects while many others can be automated.

We are interested in complete data-driven animations using motion capture, rather than the more classical workflow of keyframe animation. These tutorials are more advanced, and are only needed if you wish to animation your own custom character with motion-capture data. The following Motion Capture Rig (MC Rig) tutorials were developed by the DMD Motion Lab to provide a clear, consistent pathway to rig character models for motion-based animation.

This video shows how to rig a character for motion capture in Maya. Several fail points are clearly explained to move toward a stable, usable MC Rig for working with motion capture data. This video focuses on the steps in Fig 2a, 2b and 2c.
