A script I have developed for my rig in Maya.
Super fast, the dynamic result can be seen in real time in the view port.

I am using a simple expression making a delay in position on a locator. Then I am using different locator to drive the chain of joints.

One chain of joints is used as an input animation, and the other one is the result plus dynamic on it.

There is possibility to change the damping, the springiness, add some force to simulate a gravity or wind, and add some random noise to the movement for a more organic result.

I am mainly using this in my rig for animal ears, tails, little pieces of fabric, but there is many possibilities as it is shown with the carriage.

Hmm…it looks like things are taking a while to load. Try again?
