I am a 3d professional artist for a long time, I have to say I have read hundreds of books, watched hours of training videos, read pages of internet tutorials anything related to 3d animation. No other training material comes even close to things I have learned reading this book. It is a treasure that you have to keep somewhere close to your desk as a reference, whether you are modeling a character head, building blend shapes or rigging . I have used the techniques successfully in many projects. I thank Jason Osipa for writing this book and for teaching me how to build superior 3D characters. This is my second SS book, I also have the first edition. This 2nd edition is a lot different then the first.
