Tom grew up in New Zealand. He is a lecturer in design and also works as an artist. He has picked up UDK over the last few years, having worked previously as a 3D artist on games using 3ds Max and Maya. You can learn more about his work at www.tomofnz.com.
I'd like to thank Mike Prinke for his contribution to the last chapter on Scaleform, for the programming, and for the reviews. For getting this book done, I owe a lot to the kindness and patience of Cindy Devina for keeping me going during my first book commission. I'd also like to tip my hat to the members of the UDK forum, particularly those who helped me with particular problems, including slowJusko, Adam Jaggers, EFF, Xendance, Blade[UG], silsin, John J and Matt Doyle. Thanks also to Hywel Thomas (http://www.3dality.co.uk/) and Ryan Pelcz: (http://pelcz.squarespace.com/ for their very helpful UnrealScript snippets. I'd also like to thank Wilson D'souza and Aaron Rosario for smart and cogent development guidance and support.
Mike Prinke is an MFA graduate student in SCAD's interactive design and game development program. During his studies, he has assisted many projects and works with a wide variety of tools, with special emphasis on Unreal, Kismet, UnrealScript, and Scaleform/Flash, and he is also conducting his MFA thesis on choice-driven narrative in games.
I want to give great thanks to Aram Cookson, without whom I would not have been equipped to work on this book. I also want to thank Timothy Valuato, who showed me how cool it can be to teach.
