This book can be easily be mistaken as another Pixar artbook. The quality and selection of art included is huge.
There's lots of character and set design. Interestingly, there are pages with characters and photos of materials they used for texturing their 3D models. Tips are given on how texturing is approached on the film.
You'll see characters evolve from pencil drawings to 3D models and clay. They have included a few photos of rendered models without colours and textures, which I thought was quite cool.
Hundreds of drawings fill the pages. You won't see a lot of movie stills, which is great, of course.
Blue Sky Studio takes you through the process of creating and art directing the design of the movie. It's well worth the money for any artbook collectors. There's plenty to read and look at.
