Kennedy for helping to keep this book on course. Thanks to Bridget Dash and Aida Cazares for proofreading. And special thanks to my mom, Nandell for helping out as often as she could. Last, I want to send thanks to Alice. She encouraged and helped me on many a night as I drank my sixth cup of coff ee trying to fi nish one thing or another. vii CHAPTER 1 Pipeline and Modeling Guidelines T he pipeline is the path that assets travel to make it into movie or game. It is important to have a solid, working pipeline in place before beginning production. Who is the fi rst person to touch a model once the concept art is done? Where does a character go after it has been modeled? What happens if a model needs to go back for revisions? These are all question that should be answered before any art is created. Yes, it does add some extra work before you can get to the fun part of creation, but it will save countless hours during actual production. While this book will be focusing on modeling, be aware that a pipeline encompasses all aspects of a production. At any given time, you should be able to locate art assets. Thus it is very important to become familiar with how production pipelines work. 1
