Unity Editor Development Seven-script creation model

Describe:

In fact, this tutorial is everywhere, what I really want to do is to divide the model into n equal portions to achieve dynamic loading. But I've been searching the internet for a long time, and there's no search

To the right way, or not to write clearly, reluctant to put all the code out. Or is the cut of the terrain, most want is, t4m Brush finished straight

Then divide the model into n points, so you can only bitter from the most basic of the mesh to learn it.
