The workflow for adding a hook is pretty straightforward. You tab into Edit mode and select at least one vertex or control point. Then you press Ctrl+HimageHook to New Object. An Empty is created at a location that's the median point of all your selected vertices or control points. You also get a new modifier added to in Modifiers Properties, as shown in Figure 11-5.

And using the options in the Hook modifier, you can control how much influence the hook has over these vertices or control points. The following example gives you a clearer understanding of adding and modifying the influence of hooks:
