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 animated Proportional Editing.

Poglej Tudi

This documentation refers to the Hook Modifier specific to the Grease Pencil object. For uses with other object types refer to the general Hook Modifier.

Options

The Hook modifier.

Object

The name of the object to hook points to.

Vertex Group

Restricts the effect only to a vertex group.

Strength

Adjust this hooks influence on the stroke points, were (0.0 to 1.0) (no change to fully follow the hook).

Falloff

Type

This can be used to adjust the type of curve for the Strength attenuation. You can also define a custom curve to get a much higher level of control.

Radius

The size of the hooks influence.

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.

Influence

See Influence Filters.

Opomba

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 a hook to manipulate a vertex group (right eye of the monkey).
