Hooks

Hook Modifiers are used to deform (for precise transformations or for animation) meshes or curves by attaching objects to verts or points: in Edit Mode the Hooks menu is available using a Ctrl+H or selecting from Vertex > Hooks for meshes or Control Points > Hooks for curves. Hooks on Cablerator add some functionality to native hooks functions:

Add Aligned Hooks;
Add a Signle Hook;
Apply Hooks to Selected;
Remove Hooks from Selected;

Add Aligned Hooks

Add a specified (in Preferences) empty to all selected curve points. Empties will be aligned with point handles. The difference with a native Hook to New Object command is that the native command creates a one hook for all selected points and this hook object has no orientation.

Additionally:

It’s possible to attach selected points to an existing object:

select an object in Object Mode first;
then curve(s);
switch to edit mode and select the points to attach;
run the Add Aligned Hooks to attache the selected points to the object;

Add a Single Hook

This fuction will add a single hook for all the selected points. This is moslty used to control several points simultaneosly, for example for using with cables created with Create a Mass function.

Apply Hooks to Selected

This function will apply Hook modifiers:

if a hook object is selected, all modifiers with this Hook will be applied, if the object is empty, it will be removed;
if a curve is selected, all curve Hook modifiers will be applied, hooks (if they are empty) will be removed;

Remove Hooks from Selected

This function will remove Hook modifiers:

if a hook object is selected, all modifiers with this Hook will be removed, if the object is empty, it will be also removed;
if a curve is selected, all curve Hook modifiers will be remmoved, hooks (if they are empty) will be also removed;
