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.

Using squash and stretch


The animators at Disney, notably Frank Thomas and Ollie Johnston, stated that the animation principles were discovered instead of defined. Among those discoveries, arguably the most important is the fact that organic bodies squash and stretch its shapes during movement.

Most people associate this principle only with cartoony and exaggerated animation, but small amounts of squash and stretch are very welcome to "realistic" types of motion to help emphasize extreme poses. That's why it's a good idea to have a squash and stretch enabled character rig.

How to do it...

  1. Open the file 007-Stretch.blend. It has our character Otto making a jump, just like the result of our previous recipe on anticipation. To enhance the feeling of impulse and help lead the eyes of our audience, we're going to add a little squash and stretch to the torso and legs.

    First, the torso. Our rig enables us to stretch the torso region by simply scaling the desired controllers. In our scene, the character...
