30: Character Setup From Rig Mechanics to Skin Deformations: A Practical Approach



Monday, Full Day
8:30 am – 5:15 pm
Room 006CD

How body rigs, face rigs, pipeline integration, and muscles are used in character setup for rig mechanics and skin deformations, with an emphasis on practical, production-tested approaches that use off-the-shelf products.

Prerequisites
Working knowledge of high-end 3D software and understanding of basic 3D animation concepts such as inverse and forward kinematics, key frames, geometry types, and deformations. Highly recommended: ability to script and write expressions. Working knowledge of Maya or Softimage XSI is an advantage.

Topics
Module 1: rotation order, extra controls, selection masks, mirroring controls, feet and leg setup, IK fingers, limit notification, automatic positioning of animation controls.

Module 2: multi-layered rig setup, blending between behavioral and hand keyframe animation.

Module 3: Improving skin deformations, workflows, bones geometry (acquiring and reassigning skin weights), muscles (anatomy and layering deformers).

Module 4: Face rig (facial modeling, modeling in polygons, anatomy, sub-divided surfaces, proper arrangement of geometry), jaw setup (multiple-joint jaw rigs with control expressions), facial deformers (using wire deformers, lattices, and blend targets to create expressions).
