This document summarizes Rich Diamant's presentation on using Autodesk Mudbox for modeling characters in Autodesk 3ds Max and Maya. It discusses modeling methods for matching high resolution detail to arbitrary meshes. It also describes the character modeling pipeline used for Uncharted: Drake's Fortune, including the goals of realistic characters that emote well and look good close up for both cinematics and games. Key parts of the pipeline included using arbitrary meshes with blend shapes, creating wrinkle maps in Mudbox, and ensuring models met budget and quality goals for the PlayStation 3.

Uncharted: Drake’s Fortune Pipeline: •  Uncharted: Drake’s Fortune’s Goals –  Realistic Human Characters •  Must emote with wrinkle map technology •  Must look good from close up for both cinematics and in game •  Must be used for promotional material •  Must be efficient and in budget for in game assets
Possible pipelines: •  Arbitrary Mesh vs Base Mesh –  Same base model for every character? –  Blend Shapes vs Joints for facial deformation?
Pre E3 2006: •  Base Mesh

Comparison
Where to go from there: •  Identify new problems and solutions with arbitrary meshes –  Problems •  Keeping models in sync •  Blend Shapes?
Solutions: •  How to keep arbitrary mesh and high mesh in sync –  Organization was key •  Blend Shapes? •  Created custom tools

Back to the Goals: •  Realistic Human Characters –  Must emote with wrinkle map technology –  Must look good from close up for both cinematics and in game –  Must be used for promotional material –  Must be efficient and in budget for in game assets

How we created wrinkle maps: •  Lowest level from Mudbox was Wrap deformed to the in game Arbitrary mesh –  When the in game mesh deformed with joints, it moved the Mudbox mesh accordingly
Autodesk Mudbox
•  Sculpted a new pose with new wrinkles
•  Sculpted a new pose with new wrinkles
Autodesk Mudbox
•  Generated a new normal map from the in game posed mesh to the new sculpted pose
•  Defined normal map regions on in game mesh –  Custom tool written to define regions and export to game engine

Back to the Goals: •  Must be efficient and in budget for in game assets –  The Playstation 3 and our engine allowed us to really push the envelope in regards to texture budgets and polygon budgets •  10 – 15 megs per main character of compressed texture memory •  20 – 30 thousand polygons per main character
Postmortem: •  Happy with our decision to use arbitrary meshes •  Tools were important •  Not happy with keeping models in sync
