跟随 Adam Spring 的脚步，探索使用 Maya、ZBrush、Wrap 和 Photoshop 的高级面部混合变形网络。他演示的技术正是 Adam 在众多电影长片和 AAA 级游戏过场动画项目中运用过的，例如《使命召唤》和《爱，死亡和机器人》。
在这个为期 7 小时的工作坊中，艺术家们将学习如何从扫描数据中提取混合变形，并将其组织成基本变形和组合变形。Adam 还将演示如何利用扫描数据生成皱纹和血流图，这些图将用于在 Maya 节点编辑器中构建动态着色器。此外，他还会简要演示如何使用 Unreal Engine LiveLink 应用程序在 iPhone 上捕捉面部动作数据。
本次工作坊主要涵盖的软件包括 Maya、ZBrush、Wrap 和 Photoshop。Adam 还使用了免费的 Maya 插件 Simplex，它有助于整理所有面部混合变形。对于没有 iPhone 的学员，Adam 会在工作坊中提供项目文件中的原始关键帧数据。
本次工作坊中使用的 3D Scan Store FACS 套装目前不对公众开放；Adam 建议艺术家使用自己的 FACS 扫描或参考模型来获得最丰富的经验。
Explore advanced facial blendshape networks with Adam Spring using Maya, ZBrush, Wrap, and Photoshop. The techniques demonstrated showcase the very methods Adam has utilized on numerous feature films and AAA game cinematic projects, including Call of Duty and Love, Death & Robots.
In this 7-hour workshop, artists will examine the extraction of blendshapes from scan data and learn how to organize them into primary and combination shapes. Adam will also demonstrate how to utilize the scan data to generate wrinkle and blood flow maps, which will then be used to construct the dynamic shader within the Maya node editor. He will also provide a brief demonstration of how to capture facial motion capture data on an iPhone using the Unreal Engine LiveLink app.
The main software covered in this workshop is Maya, ZBrush, Wrap, and Photoshop. Adam also uses the free Maya plugin, Simplex, which is helpful for organizing all of the facial blend shapes. With this workshop, Adam provides the raw key frame data in the project files for anyone who doesn’t have access to an iPhone.
The 3D Scan Store FACS set featured in this workshop is not currently available to the public; Adam recommends that artists use their own FACS scans or model from a reference to gain the most experience.
