Modificador Hook

The Hook modifier is used to deform a mesh, curve or lattice using another object (usually an empty or a bone but it can be any object). As an object specified as hook moves, it pulls vertices or control points from the geometry with it. You can think of it as animated Proportional Editing.

While hooks do not give you the fine control over vertices movement that shape keys do, they have the advantage that you can select vertices directly for manipulation.

To assign selected vertices (in Edit Mode) you can use the Assign button on the modifier panel or use the Add Hook menu.

Opções

O modificador Hook.

Objeto

O nome do objeto ao qual enganchar os vértices.

Vertex Group

Allows you to define the influence per vertex.

Useful when you want something other than a spherical field of influence.

Inverter <->

Inverte a influência do grupo de vértices selecionado, o que significa que o grupo agora representa vértices que não serão deformados pelo modificador.

The setting reverses the weight values of the group.

Strength

Adjust this hooks influence on the vertices, were (0.0 to 1.0) (no change to fully follows the hook).

Since multiple hooks can work on the same vertices, you can weight the influence of a hook using this property.

The following settings are only available in Edit Mode:

Redefinir

Recalculate and clear the offset transform of the hook.

Re-centralizar

Set the hook center to the 3D cursor position.

Select

Select the vertices affected by this hook.

Atribuir

Atribui os vértices selecionados para este gancho.

Aviso

The Hook Modifier stores vertex indices from the original mesh to determine what to affect. This means that modifiers that generate geometry, like Subdivision Surface, should always be put after the Hook one in the stack. Otherwise, the generated geometry will be left out of the hook’s influence.

Decaimento

Tipo

This can be used to adjust the kind of influence curve that the hook has on the mesh. You can also define a custom curve to get a much higher level of control.

Raio

O tamanho da influência do hook.

Uniform Falloff

Essa configuração é útil quando usando hooks em objetos escalonados, especialmente em casos onde escala não-uniforme esticaria o resultado do hook.

This is especially useful for lattices, where it is common to use non-uniform scaling.

Exemplo

Empty used as Hook to deform a subdivided cube.
