I've never been into the idea of producing tutorials as such, but during my time spent using Cinema4D I've worked out some nice solutions to various things which I'd like to share....
Bendy IK Limbs:
I've been playing around with various solutions for character rigs, where the limbs aren't quite as stiff as real-world examples. The aim of the solution was to create a more cartoonish based limb rig, whilst still using IK.
You'll need to be familiar with rigging in Cinema4D to follow the steps. Leave me a comment if you have any questions.
