Ondulations, tails (and other objects) waves. (Patreon)

A little example of a tail effect using balls for directions to help you keep on track and not be lost while animating this motion.

The more the balls cross, the more the tail will wave stronger from a side to another! You can mix both and have different effects

 (wind going in many directions, creating more variations of waves, perspective with smaller or bigger balls etc etc etc.)

The little blue spot helps to stay connected to the base, so the tail is not "flying" away, it's a common mistake and it can be hard to correct if you already go too far on the animation so be careful when you do it.

Hope those can help! Good luck on animating!
