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.
- The name of the object to hook points to.
- The size of the hooks influence.
- 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 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.
See Influence Filters.
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.
