I came across a posting from MegaFill showing a quick tip on how to track vertices of polygon objects in Cinema 4D using VERTEX TRACKER that was created by Robert Sarosi, available on XpressoPresets.net. Vertex Tracker for Cinema 4D is a useful preset to track vertexes like the name suggests. The tracking is updated live so you can freely change the deformations and the animation and the tracker still keep up. You can use the tracked position to a lot of things… for example: you can parent a light to a deformed mesh’s vertex or use vertexes as particle emitters. Check out Cinema 4D Vertex Tracker here.
