Face control is one of the most difficult parts of character animation. And it is necessary to create proper controls for the character so that the animator is comfortable. This technique is also used in studios like Pixar and Disney. This technique is that the surface of the character itself becomes controllable.
And this reduces the crowds of controls. And the speed gives the animator more work. I’m going to use this technique in my first project. This is something I like very much. However, in the end, we need some controls other than these.
