可以生成和控制C4D顶点法线，实际上其他软件像3ds Max, Maya这些都是支持点法线编辑的，C4D只支持导入和渲染，但是没有一个很可见的方法去编辑，Vertex Normal Tool这个插件可以完成这个目的
Vertex Normal Tool is a plug-in for C4D which adds a tool for creating and manipulating vertex normals on polygon objects in C4d. Virtually all other high-end 3d applications (3ds Max, Maya, etc.) support vertex normal editing and while c4d supports importing, rendering, etc.. vertex normals it lacks any interface or tool for creating or editing them. This plug-in aims to address that problem by giving the artist full control over vertex normals.
安装步骤：
- 将Vertex Normal Tool文件夹拷贝到C4D安装目录的plugins里面就行
