London based animation and VFX Artist for Monk Studios, Pryce Duncalf shares a tip on creating dynamic IK chains in Cinema 4D. Using joints, IK, SP Turbulence, Skin and Loft, Pryce imparts a really useful trick for animating things like tentacles.
use the standard particle effectors to animate a dynamic IK chain of joints
Pryce uses the standard particle effectors to animate a dynamic IK chain of joints. Extending that premise a bit, Pryce uses some Xpresso along with the hierarchy iterator and other nodes to apply user data across a group of objects, making it easier to animate. Pryce notes that iterators are a tricky thing grasp, but they are really powerful because they can save a lot of time when creating rigs in Cinema 4D, like a dynamic rig for joints.
