In this part we create an automated walk cycle with iExpressions. You just need to keyframe the position of the character and the iExpressions-based rig animates the legs and the body automatically such that the character is walking.
In this part, we connect the skeleton to our character using the puppet tool. You learn the basics, but also some advanced tips for this workflow. For example, you learn how to achieve that puppet pins on the skirt of the character are influenced by the bones of both legs simultaneously.
This iExpression allows to animate an entire arm by just specifying the point where the hand should be - the expression calculates the rotation of all arm segments accordingly (using Inverse Kinematics, IK). You tell where the arm should move - the expression knows how.
