Grease Pencil tem seu próprio conjunto de modificadores. Modificadores são operações automáticas que afetam um objeto de forma não-destrutiva. Com modificadores, você pode realizar vários efeitos automaticamente que de outra forma seria tedioso fazer manualmente e sem afetar a geometria base do seu objeto.

With Geometry Nodes, it is possible to create custom Grease Pencil modifiers.

They work by changing how an object is displayed and rendered, but not the geometry which you can edit directly. You can add several modifiers to a single object forming the modifier stack and Apply a modifier if you wish to make its changes permanent.

There are four types of modifiers for Grease Pencil:

Edição: Essas ferramentas são similares às do tipo Deform (veja abaixo), entretanto, elas geralmente não afetam diretamente a geometria do objeto, mas algum outro dado, como grupos de vértices.
Generate: O grupo de modificadores Generate inclui ferramentas construtivas que tanto mudam a aparência geral ou adicionam nova geometria a um objeto automaticamente.
Deformar: O grupo de modificadores Deform apenas muda a forma de um objeto sem adicionar nova geometria.
Color: O grupo de modificadores Color muda a cor de saída do objeto.

Interface¶

Cada interface de modificador compartilha os mesmos componentes básicos como modificadores para malhas.

Veja Modifiers Interface para mais informações.

Applying Modifiers¶

Applying a modifier makes the effects of the modifier «real»; converts the strokes to match the applied modifier’s results, and deletes the modifier.

When applying a modifier to an object that shares Object Data between multiple objects, the object must first be made a Single User which can be performed by confirming the pop-up message.

Aviso

Applying a modifier that is not first in the stack will ignore the stack order (it will be applied as if it was the first one), and may produce undesired results.

Apply (Active Keyframe) Ctrl-A: Applies the modifier for the current keyframe.
Apply (All Keyframes): Applies the modifier for all keyframes.

Nota

With Geometry Nodes it is possible to add new layers to the geometry. When applying, this will create a single keyframe on the first frame of evaluation. Layers with duplicated names in evaluated geometry will be deduplicated.

It is also possible to have layers with empty names. When applying these get renamed to Layer (and Layer.001 etc. when such a layer already exists in the original geometry).

Influence Filters¶

Most Grease Pencil modifiers share a set of options that control where the modifier is applied. These filters restrict the modifier’s effect to specific layers, materials, or geometry components.

For each filter, you can invert the selection by clicking the (Invert) icon next to the control.

Layer / Group: Restricts the effect to points or strokes of the specified layer. Alternatively, to filter by layer groups, click the icon.
Layer Pass: Restricts the effect to points or strokes in layers with a matching Pass Index.
Material: Restricts the effect to points or strokes using the specified material.
Material Pass: Restricts the effect to points or strokes whose material has a matching Pass Index.
Vertex Group: Restricts the effect to points or strokes assigned to a specific vertex group.
Custom Curve: When enabled, applies a custom falloff curve to control how the modifier’s influence varies along each stroke from start to end.

Nota

The availability of each filter depends on the specific modifier. Not all modifiers support all filters.
