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.
