AssetPostprocessor 资源处理器

ssetPostprocessor lets you hook into the import pipeline and run scripts prior or after importing assets.

AssetPostprocessor让你钩进导入管线，在运行脚本之前或导入资源之后。

Note: This is an editor class. To use it you have to place your script in Assets/Editor inside your project folder. Editor classes are in the UnityEditor namespace so for C# scripts you need to add "using UnityEditor;" at the beginning of the script.
注意：这是一个编辑器类，如果想使用它你需要把它放到工程目录下的Assets/Editor文件夹下。编辑器类在UnityEditor命名空间下。所以当使用C#脚本时，你需要在脚本前面加上 "using UnityEditor"引用。

This way you can override default values in the import settings or modify the imported data like textures or meshes.

这样你可以在导入的设置中重载默认值或修改导入的数据，如纹理或网格。
