Vertex painting in Cinema 4D

Does anyone know if it is possible to paint vertex colors (and use these in Unity) using Cinema 4D? I can’t find any information indicating this can be done anywhere.

I know it is possible with Maya and 3DMax, but I don’t have access to these programs.

Bump! Is this at all possible?

This is a very old post but, is anyone still interested in painting vertex maps in Cinema 4D?
Because now, there is a way. And it can even load and save FBX files with vertex paint information (also .OBJ files, from Zbrush).
