										<content:encoded><![CDATA[<p>本文整理自 Autodesk Community 论坛的真实问答：<a href="https://forums.autodesk.com/t5/maya-forum/maya-error-incorrectly-defined-uv-coordinates-missing-uvlist-or/m-p/7361321" target="_blank" rel="nofollow noopener">Maya Error: incorrectly defined UV coordinates, missing uvlist or uvidxs</a>。原帖有 accepted solution，下面是结合该解法写成的中文排查笔记。</p>
<h2>为什么会这样</h2>
<p>accepted solution 建议在 Arnold Diagnostics &gt; Error Handling 里取消 Abort on Error，并把 verbosity 调到 warnings + info，以便继续诊断。</p>
<h2>实操步骤</h2>
<p>这不是说忽略 UV 错误，而是先让 Arnold 给出更多上下文。之后再查模型 UV set、缺失 uvlist/uvidxs 和导入网格。</p>
<p>建议你先用一个副本或空场景复现问题，再把修复步骤应用到正式文件。Maya 的很多故障都不是单点错误，而是“场景状态、首选项、插件、驱动、路径”几层叠加出来的。</p>
<h2>最后检查</h2>
<p>渲染器报错时，日志详细度比反复点渲染更有用。</p>
<p>如果修复后短时间正常，但重启 Maya 或换机器后复发，把项目路径、用户 prefs、环境变量和插件版本也一起记录下来。这样下次就不是凭感觉排查，而是有一张可回溯的故障地图。</p>
