James Chiny (hypoly) has posted a free little plugin for Cinema 4D that is simple in form, but useful in practice. The PointCluster Plugin for C4D can assist when creating point clusters on objects.

This is a free plugin I made to help with setting up rigs for simple or complex animationsJames Chiny – Hypoly.com

It can rig up point cluster deformers on polygonal objects, deformers and even splines-  Simply select the vertices that you wish to effect, and then choose the PointCluster plugin. You can check out the C4D PointCluster Plugin over at HypolyLabs here.
