Excellent work! You've now completed this chapter and this book. At this stage, you have a solid foundation for using the following: Blend Shapes, for animating morphs and transitions across vertex states; IK, for creating arms and legs that animate easily in the designated positions; and movie textures, for playing prerendered cut-scenes and other movie files.
Also, by completing this book, you've explored almost all of Unity's extensive animation feature set, including scripting and animation curves, animation windows, particle systems, rigged skeletons, key frames, interactive elements, and more.
