直接用一级细分？在三角形附近添加“代价最少”的切边

人脸

按住C微调
Shift 增加/减少
Ctrl 画笔新建边/面
主要循环边→细化

颧骨poly→眼睑stroke→嘴唇→鼻子→调整→细分修改器预览(o键)

眼罩变平行额头→眼睛→嘴

经验

忍无可忍，将三角面藏到看不到的地方：https://blender.stackexchange.com/questions/2931/why-should-triangle-meshes-be-avoided-for-character-animation

一般会处理得扁一点

要意识到拓扑就是做角色的肌肉系统，要自然
要做成每个块都类似正方形才好吗？

完美拓扑

我想这样拓扑，其实不可以

要重做了

三角形不是恶魔

入门的时候：blender对四边形的支持比▲好，但不可避免要使用三角形时，就用吧，别执拗于变形过度的四边形
后面熟悉了，三角面都可以对周围处理，然后转换成4边形

"Allah! There is no god but He - the Living, The Self-subsisting, Eternal. No slumber can seize Him Nor Sleep. His are all things In the heavens and on earth. Who is there can intercede In His presence except As he permitteth? He knoweth What (appeareth to His creatures As) Before or After or Behind them. Nor shall they encompass Aught of his knowledge Except as He willeth. His throne doth extend Over the heavens And on earth, and He feeleth No fatigue in guarding And preserving them, For He is the Most High. The Supreme (in glory)."
[Surah al-Baqarah 2: 255]
