GN ZBrush/Maya Import/Export Tool可以在ZBrush和Maya之间进行模型导入导出桥接，会比ZBrush的GoZ插件快很多，特别是大数量模型导出的时候

The GN ZBrush/Maya Import/Export Tool is a script package to quickly import and export files in ZBrush and Maya.This tool will give you the ability to quickly switch between Maya and ZBrush, importing and exporting multiple objects at once and doing so at a much faster speed than ZBrush plugin GoZ which tends to be slow and unreliable, especially when working with a large number of objects. This tool also offers a couple of different options and allows to import/export in both MayaAscii and OBJ file format which support different features such as creases, polygroups and vertex color.

• 拷贝ZBrush文件夹里面的内容到ZBrush安装目录如下位置，默认C:\Program Files\Pixologic\ZBrush Version\ZStartup\ZPlugs64
• 将Maya文件夹里面的GN_ImportExport文件夹和userSetup.mel拷贝到Maya的脚本目录，默认文档\maya\Maya版本\scripts
