30: Character Setup From Rig Mechanics to Skin Deformations: A Practical Approach
Monday, Full Day
8:30 am 5:15 pm
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.
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.
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).
