In this tutorial Tim Clapham from helloluxx.com shows you a simple technique which will allow you to attach an object to the top of an animated Extrude with Xpresso in Cinema 4D. Although this is probably quite a simple process for a lot of users, this tutorial explores the flexibility that is offered when you use relative links in your Xpresso nodes rather than absolute links.
To take this one step further, we take the animation and 3D data into After Effects using the AEC export. In After Effects add some basic type and link it to the null objects we created in Cinema 4D.
