Hook Modifier

The Hook Modifier is used to deform stroke points using another object(usually an empty or a bone but it can be any object).

As the hook moves, it pulls points from the strokes with it.You can think of it as animatedProportional Editing.

Options

The Hook modifier.

• Object
• The name of the object to hook points to.
• Radius
• The size of the hooks influence.
• Strength
• Adjust this hooks influence on the stroke points, were (0.0 to 1.0) (no change to fully follow the hook).

Falloff

• Falloff Type
• This can be used to adjust the kind of curve that the hook has on the stroke points.You can also define a custom curve to get a much higher level of control.
• Uniform Falloff
• This setting is useful when using hooks on scaled objects,especially in cases where non-uniform scale would stretch the result of the hook.

Note

The Hook Modifier stores points indices from the original strokes to determine what to affect;this means that modifiers that generate geometry, like a Subdivision Surface Modifier,should always be applied after the Hook Modifier;otherwise the generated geometry will be left out of the hook's influence.

Example

Empty used as Hook to manipulate a vertex group (right eye of the monkey).
