Animate a fish you say? This can be an easy or tricky task. It all comes down to how effective your rig for the fish is.
Jared Walker from Super Giant Ninja, shows how you can rig and animate a fish in Cinema 4D. This is the first part of a series of tutorials that will look at later adding a smoke or ink effect that will be generated by the fishes as they swim by. The ink trails will eventually be created using TurbulenceFD in C4D
