										<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/smooth-preview-number-3-on-keyboard-crashes-maya/m-p/5027416" target="_blank" rel="nofollow noopener">Smooth preview (number 3 on keyboard) crashes Maya&#8230;</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>从原帖看症状</h2>
<p>这个帖子里的现象很典型：模型本身未必坏，崩溃发生在视口平滑预览触发显卡显示路径时。accepted solution 的有效办法是到 Preferences &gt; Display，把渲染引擎从 OpenGL 切到 DirectX 11。</p>
<h2>排查和修复</h2>
<p>处理顺序建议是：先备份场景；用一个简单立方体测试数字 3；如果简单物体也崩，优先换 Viewport 2.0 的渲染后端；之后再更新或回退显卡驱动。</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>给制作流程的提醒</h2>
<p>如果只有某个模型崩，再查非流形、历史节点和细分级别。不要把所有 Smooth Preview 崩溃都归咎于模型拓扑。</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>
