Caterpillar track

Here I have almost tried to duplicate the caterpillar tracks  hope you like it.

This done by IK spline method, by creating multiple snap shot

• by creating multiple snap shot
• And created joints for each 
• skinned them to joints and of course created spline Ik and assigned my own curve to that.
• gear is just simulated, is was keyed so that it can match the chains rotation
