Introduzione

Materials control the appearance of the Grease Pencil object. They define the base color and texture of the strokes and filled areas.

There is always only one active material in the list (the selected one). When you draw, the new strokes use the active material.

You can override the base material color using the tools in Vertex Mode or the Draw and Tint tool in Draw Mode.

The material always remains linked to the strokes, this means that any change in a material will change the look of already drawn strokes.

Grease Pencil Shader

The Grease Pencil shader creates 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 and can only be setting up on the Material Properties panel (it is not a shader node).

Riferimento

Grease Pencil materials can be created in the Material properties as any other materials in Blender. See Material assignment for more information.

The 3D Viewport can be set to Material Preview or Rendered shading, to interactively preview how the material looks in the scene.

Grease Pencil materials are data-blocks that can be assigned to one or more objects, and different materials can be assigned to different strokes.

In Grease Pencil the brush settings together with the material used will define the look and feel of the final strokes.

Materials slots in the List view also have some extra controls that help to work with materials while drawing or editing lines.

Next to the material name there are three icons buttons that control common properties of the material:

Lock (padlock icon): Toggle material from being editable.
Viewport/Render Visibility (eye icon): Toggle material visibility in the viewport and in render.
Onion Skinning (onion skin icon): Toggle the use of the material for Onion Skinning.

Show All: Turns on the visibility of every material in the list.
Hide Others: Turns off the visibility of every material in the list except the active one.
Lock All: Locks edition of all the materials in the list.
Unlock All: Unlocks edition of all the materials in the list.
Lock Unselected: Locks all materials not used in the selected strokes.
Lock Unused: Locks and hides all unused materials.
Convert Materials to Vertex Color: Only keeps necessary materials and convert all materials base color to vertex color.
Extract Palette from Vertex Color: Add all used vertex color to a new Color Palette. See Tavolozza dei Colori.
Copy Material to Selected: Copy the active material to the selected Grease Pencil object.
Copy All Materials to Selected: Copy all materials to the selected Grease Pencil object.
Merge Similar: Combines similar materials in the list and replace the strokes that use the one of the merged materials with the new one.
Remove Unused Slots: Remove all unused materials.

Lock (padlock icon): Toggle whether the active material is the only one that can be edited.
Visibility (screen icon): Toggle whether the active material is the only one that can be edited and is visible.

Grease Pencil materials use a special shader that define the appearance of the surface of the stroke and fill.
