In this online course, he goes a step further with advanced techniques to improve the deformation and control rig of your characters for more complex functionalities that truly bring them to life. Jose Antonio explains some of the most important principles of animation, such as the squash and stretch effect, which allows you to exaggerate the action and emotion effects of a character for more cartoon-like results, as well as dynamics, which can be added to elements such as clothing and hair, to save animation time.
