Grease Pencil Material Properties

Grease Pencil materials define how strokes and fills are rendered. Each stroke references a single material, and that material contains separate settings for its Stroke and Fill components.

The Material Properties panel provides tools to manage material slots, control visibility and locking, and configure the appearance of stroke and fill shading.

Material Slots

Painel de slots de materiais do Grease Pencil.

Material slots assign materials to the Grease Pencil object. Each stroke stores a reference to one of these material slots.

The active material is used for newly created strokes. Existing strokes keep their assigned material unless changed manually.

Next to each material name are controls for common visibility and editing options:

/ (Show/Hide in Ghosts)

Controls whether the material is visible in Onion Skinning previews.

/ (Hide/Show Material)

Toggles the visibility of strokes using this material in the viewport.

/ (Lock/Unlock Material)

Prevents strokes using this material from being edited in Edit Mode.

Especiais

These operators provide bulk control over material visibility and locking:

Show All

Enable visibility for all materials.

Hide Others

Hide all materials except the active one.

Lock All

Lock all materials to prevent editing.

Unlock All

Unlock all materials for editing.

Lock Unselected

Lock materials not used by the currently selected strokes.

Lock Unused

Lock and hide materials not assigned to any stroke.

Copy Material to Selected

Copy the active material to selected Grease Pencil objects.

Copy All Materials to Selected

Copy all material slots to selected Grease Pencil objects.

Remove Unused Slots

Remove material slots that are not assigned to any strokes.

Lock & Visibility Controls

(Isolate Material)

Lock all other materials so only the active material can be edited.

(Isolate Material)

Hide all other materials so only the active material is visible.

Superfície

Shader panel with only Stroke component enabled.

The Surface panel defines the visual appearance of strokes and fills. Each material contains two independent components:

• Stroke – Controls the outline rendering.

• Fill – Controls the interior rendering of closed strokes.

Each component can be enabled or disabled independently.

Stroke

The Stroke component defines how the line itself is drawn.

Line Type

Defines how the stroke geometry is rendered.

Linha:

Renders a continuous line connecting stroke points.

Dots:

Draws a circular shape at each stroke point. Points are not connected.

Squares:

Draws a square shape at each stroke point. Points are not connected.

Style

Determines how the stroke is shaded.

Solid:

Uses a uniform base color.

Texture:

Uses an image texture mapped along the stroke.

Imagem

Image data-block used as the texture source.

Blend

Mix factor between the texture and the Base Color.

UV Factor

Controls texture scaling along the stroke length.

Placement Dots Squares

Defines how dots or squares are distributed along strokes.

Contagem:

Places a fixed number of dots on each stroke segment.

This mode keeps the number of generated shapes consistent regardless of the stroke length or thickness.

Contagem

Number of dots to place on each stroke segment.

Raio:

Places dots based on the stroke radius, adapting the spacing to the stroke thickness.

Larger stroke radii produce wider spacing between dots, while smaller radii place them closer together.

Espaçamento

Distance between dots as a percentage of their diameter.

Lower values create overlapping or tightly packed dots, while higher values increase the gap between each generated shape.

Density:

Places dots based on the stroke length.

Longer strokes generate more dots while shorter strokes generate fewer, maintaining a more uniform visual density along the stroke.

Density

Number of dots generated along the stroke length.

Higher values create more densely packed dots.

Cor Base

The primary color of the stroke.

Holdout

Makes the stroke act as a mask, removing color from underlying strokes and fills.

Alignment

Controls orientation of Dots and Squares.

Caminho:

Aligns to the drawing direction and object rotation.

Objeto:

Aligns only to the object’s rotation.

Fixo:

Aligns to screen space.

Rotação

Rotates the Dots or Squares shapes. Limited to -90° to 90°.

Self Overlap

Controls how overlapping parts of the same stroke blend, particularly with semi-transparent materials.

Aleatorizar

Adds random variation to generated dots or squares to create a less uniform appearance.

Tamanho

Randomly varies the size of generated shapes.

Higher values increase the variation between larger and smaller dots.

Strength

Randomly varies the opacity of generated shapes.

This can create a more natural or textured appearance.

Rotação

Randomly rotates generated shapes around their center.

This is most noticeable when using square shapes.

Hue

Randomly varies the hue of generated shapes.

Saturation

Randomly varies the saturation of generated shapes.

Value

Randomly varies the brightness of generated shapes.

Noise Scale

Controls the scale of the random noise pattern.

Lower values create smoother variation across the stroke, while higher values produce more rapidly changing randomization.

Preencher

The Fill component controls rendering of closed stroke regions.

Style

Defines how the fill is shaded.

Solid:

Uses a single base color.

Gradient:

Blends between two colors.

Gradient Type

Linear:

Blends along one axis.

Radial:

Blends outward from a center point.

Texture:

Uses an image texture.

Imagem

Image data-block used for the fill texture.

Texture

Cor Base

Primary fill color.

Secondary Color Gradient

Secondary color used for gradients.

Holdout

Makes the fill act as a mask, removing color from strokes underneath.

Blend Gradient / Texture

Controls mixing between Base Color and the gradient or texture.

Flip Colors Gradient

Swaps Base and Secondary colors.

Location X, Y Gradient / Texture

Offsets gradient or texture coordinates.

Rotation Gradient / Texture

Rotates the gradient or texture mapping.

Scale X, Y Gradient / Texture

Scales the gradient or texture mapping.

Clip Image Texture

Prevents texture tiling when enabled.

Pass Index

Custom integer identifier for use in modifiers and compositing. Can be used to target specific materials in Grease Pencil Modifiers.
