我可以替换三部电影中使用的头像吗。js示例：你是一个拥有自己化身的人类吗？

Question

我试着用这三个。js示例将我的头像替换为我自己的头像。我研究了本例中使用的文件，不明白为什么不能替换它。我创建了一个带有变形目标（默认为1个变形目标）和骨架的化身。我将变形目标导出为变形动画，将骨架导出为骨骼动画（这似乎需要变形目标和骨骼动画才能工作）。当我在浏览器上打开javascript文件时，我只能看到dat gui控件，但不会显示化身。我怎样才能做到这一点？

其他文件：umich_ucs。js，UCSCharcater。js，UCS_配置。json，探测器。js，dat。桂。三分钟。min.js，轨道控制。js

我已经弄明白了。问题是缩放。我的头像太大了，所以我看不到它显示在浏览器上。
