This is a fantastic little xpresso setup to create a kerning solution for C4d. The author, Yader, has a host of really great quick tips and tricks for Cinema. I recommend browsing his vimeo page as often as possible.
It’s amazing to me that Maxon has not included kerning in their software. Cinema 4d has always promoted itself as the friendliest solution for graphic design and has had some of the most powerful 3d text tools since its inception.
