Base Mesh
基础模型（似为低模）
Block out a simple shape. It's important to keep it all quads of equal size before sculpting to get the best results out of Zbrush or Mudbox.
拉出一个基本形体，在这个形体进入zbrush和mudbox的雕刻阶段之前，保持所有面相近很重要（完全不明白的译者….）
Sculpt
雕刻
With simple sculpting, it's easy to get a rocky organic shape. Start with the largest shapes and slowly reduce your brush shape (note: if it

Close-Up
收尾
The high detail mesh is just under 400,000 triangles. Working with a mesh this detailed can be a headache, so it's good to get used to it
高模会有400000个面，一个这样细节的网格模型很令人困扰，所以最好习惯于此

至此，模型拥有了惊人的细节。
Low Poly
低模
Build a low poly mesh based closely on the high detail. It may help to copy the high and optimize it. Not for the final low, but to use as a 以高模为基础创建一个低模，它将用于对高模的继承和优化，（下面这两句不明白）
