In this CINEMA 4D tutorial we will learn how to use CINEMA 4D's node-based Expression System, XPresso. We will talk about the principles of XPresso, learn how we can create nodes and navigate in our node tree. After this short introduction we will cover what vectors and matrices are and what we can do with them. We will work our way through a few practical examples where we'll show you different nodes and techniques. Our final project will be a dynamic jellyfish rig which is fully driven by our node setup. Software required: CINEMA 4D R14.
