This tutorial will show how to use Twixtor Pro and RE:Fill and Trapcode’s Particular to turn a real-world person (or any object) into what looks like the person is made out of particles.  We will be using the motion calculated from the object to throw the particles off the person, which provides more interaction between the person and the particles.   You will need Twixtor Pro and RE:Fill by RE:Vision Effects and Particular  (by Trapecode for Red Giant) for this tutorial.
