Here's another great animation tutorial by George Maestri, the original animation producer of â€œSouth Parkâ€. Earlier we posted his tutorial 'Anatomy of a Walk'. This time, he explains the fine details of animating reptiles and of snakes in particular.
Aside from being useful when animating, this article has been a bit of general education for me: did you know that snakes have many modes of motion? George discusses serpentine motion, sidewinding, concertina motion, rectilinear motion and more. He then goes on to explain the best tools to use to create these modes of motion using animation tools.
His conclusion is that Spline IK (a mix between spline animation and IK chains) is the best way to animate snakes. I'm unsure if Blender's new armature system has this functionality. Would anyone care to enlighten me about that?
