In this tutorial, you'll learn how to create secondary motion in Cinema 4D using Soft IK, where parts of a character, like antennae, hair or floppy ears, wobble and bounce automatically as the character moves.
You'll look at how to create Soft IK, and how it can be applied to a character. First, you'll produce your character from a Sphere, using Extrude to give it details, and a Subdivision Surface to smooth it out. You'll add a little bit of colour to make it stand out.
Then, using the Joint Tool, you'll create the necessary joints for your character, then bind them together. Creating an IK Chain comes next, followed by adjusting the settings in the Dynamics tab to allow you to get that perfect secondary motion.
