Blender 2.5 Character Animation Cookbook

Overview of this book

Blender is an open source 3D graphics application that can be used for modeling, rigging, animating, rendering and thousands of other things. While modeling characters isn't the biggest of your worries, animating them to make them feel as-good-as alive is what differentiates a professional from an amateur. This book offers clear, illustrative, and easy-to-follow recipes to create character rigs and animations for common situations. Bring your characters to life by understanding the principles, techniques and approaches involved in creating rigs and animations, you'll be able to adapt them to your own characters and films. The book offers clear step-by-step tutorials, with detailed explanations, screenshots and support files to help you understand the principles behind each topic. Each recipe covers a logical step of the complete creation of a character rig and animation, so you're not overwhelmed with too much information at once. You'll see numerous examples and screenshots that guide to achieve various rigging and animation tasks, logically separated so you can understand each in detail. The rigging topics are divided by each region of the body (torso, limbs, face, eyes), and further separated by the specific topic (neck, fingers, mouth, eyelids, etc) for clarity. All rigging tasks are accomplished with the built-in tools in Blender, without the complexity of coding custom Python behaviors or user interface elements. The animation topics deal with common situations found in real world productions, showing good practices to understand and overcome the challenges.

Tracking animation arcs


Arcs. Animators are obsessed with arcs. This is because most organic actions happen along an arched path, giving fluidity and realism to human and animal motions.

Mechanical movements, on the other hand, usually happen along straight paths.

Whether you are animating an organic being or a mechanical device, Blender allows the tracking of motion paths. This is extremely helpful when animating, and can give you answers when you watch the movements you create and feel that "something isn't quite right".

How to do it...

  1. Open the file 005-Tracking.blend. It has our character Otto with some very basic and unfinished animation of a jump. Let's track the arcs so we can make our animation better.

  2. First, let's track the path made by the Hips bone, since it's the center of gravity for our character. Select it, make sure you're on side view (Numpad 3), go to the Properties window, on the Object Data tab, and find the Motion Paths panel. Make sure the options Frame Numbers, Keyframes...
