Rig it Right! Maya Animation Rigging Concepts

Book Description

Rigging a character can be a complicated undertaking. Move from a bi-pedal character to a quad- or poly-pedal and, well, things just got real. Where do you begin?

Unlike all of those button-pushing manuals out there, Rig it Right! breaks down rigging so that you can achieve a fundamental understanding of the concept, allowing you to rig more intuitively in your own work. Veteran animation professor Tina O’Hailey will get you up and rigging in a matter of hours with step-by-step tutorials covering multiple animation control types, connection methods, interactive skinning, BlendShapes, edgeloops, and joint placement, to name a few. The concept of a bi-ped is explored as a human compared to a bird character allowing you to see that a bi-ped is a bi-ped and how to problem solve for the limbs at hand. After you have moved beyond basic bi-pedal characters, Rig it Right! will take you to a more advanced level where you will learn how to create stretchy rigs with invisible control systems and use that to create your own types of rigs.

    • Hone your skills every step of the way with short tutorials and editable rigs that accompany each chapter. (17+ rigs!!)
    • Read "Tina’s 10 Rules of Rigging" and build the foundational knowledge needed to successfully rig your characters.
    • Visit the companion website (www.focalpress.com/cw/ohailey) and expand your newfound knowledge with editable rigs, exercises, and videos that elaborate on techniques covered in the book
    • Coffee is not required – but encouraged.
