Introduction

Materials control the appearance of the Grease Pencil object. They define the 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.

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

Setting up Materials

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 LookDev 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.

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