Material Browser
This browser is just active when the Keep material assigned to Brush Pin is activated.
The colors for the grease pencil are materials each. For the grease pencil type Blank you will just have one color available. For this type you have to create new materials in the material tab first when you need more colors. But the other two types, strokes and monkey, comes with a few base materials already. Which can be found in the Materials tab.
The tool settings above the header shows this panel too. And here you can quickly change the color of a material. It is explained in the chapter Materials Tab.
Drop down box

Stroke Method
Controls how Grease Pencil strokes are treated during editing and rendering. Useful for defining whether strokes act as outlines, fills, or both, depending on the drawing workflow
Stroke1
Points are interpreted as line strokes only. Produces visible outlines without fill regions. Best for sketching, inking, or line-based animation.
| Entry | What it does |
|---|---|
| Fill | Points are interpreted as fill regions only. Creates solid shapes without visible outlines. Useful for coloring, shading, or shape-based animation. |
| Both | Points contribute to both stroke outlines and fill regions. Produces combined line + fill geometry. Ideal for workflows where outlines and fills need to remain linked. |
Caps Type
Controls the shape of stroke endpoints (caps). Useful for defining whether strokes end with rounded tips or flat edges, affecting both aesthetics and readability in drawings.
| Entry | What it does |
|---|---|
| Round | Ends strokes with a smooth, circular cap. Creates softer, organic-looking stroke endings. Ideal for calligraphy, sketching, or expressive linework. |
| Flat | Ends strokes with a straight, cut-off edge. Produces sharp, mechanical-looking stroke endings. Useful for technical drawings, graphic styles, or when clean edges are required. |
