Grease Pencil Shader

../../_images/grease-pencil_materials_grease_pencil_shader_panel.png

Shader panel with only Stroke component activated.

The Grease Pencil Shader create a material that can work with strokes and/or filled areas of a Grease Pencil Object.

Stroke and fill components has it own section panel and they can be enabled with a checkbox on the panel header.

Stroke only has effect on the lines and Fill only on the areas determined by closed lines (by connecting the lines start and end points).

Nota

The shader is not yet a BSDF capable shader to interact with Blender lights and can only be setting up on the Material Properties panel (it is not a shader node).

Properties

Stroke

When enabled, the shader use the stroke component. The Stroke component controls how to render the edit lines.

Mode Type

Defines how to display or distribute the output material over the stroke.

Line
Connects every points in the strokes showing a continuous line.
Dots
Use a disk shape at each point in the stroke. The dots are not connected.
Boxes
Use a box shape at each point in the stroke. The boxes are not connected.
Style

The type of the material.

Solid

Use a solid color.

Color
The color of the stroke.
Texture

Use an image texture.

Image
The image data-block used as an image source.
UV Factor
The image size along the stroke.
Use As Stencil Mask

When enabled, use the image alpha as a stencil mask.

Color
Color to use on not transparent areas of the image.
Mix Color

When enabled, mix the image with a certain color.

Factor
Mixing amount.
Color
The color to mix.
Alignment

Defines how to align the Dots and Boxes along the drawing path and with the object’s rotation.

Path
Aligns to the drawing path and the object’s rotation.
Object
Aligns to the object’s rotation; ignoring the drawing path.
Fixed
Aligns to the screen space; ignoring the drawing path and the object’s rotation.
