人脸
按住C微调
Ctrl+Shift+左键后按F确认填充
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
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
"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]
