Next we'll explore another important aspect of body morphology—the muscles. Coming to our aid is a versatile new feature of Editable Poly called Paint Deformation. Paint Deformation allows us to push and pull an object's surface with a customizable brush. It's one of the closest digital equivalents to sculpting from clay and can be extremely useful in adding organic detail to a model.
In this example, we're going to take the (rather puny) upper body from the previous exercise and bulk it up.
