Grease Pencil Layers panel.

Grease Pencil objects can be organized into a tree known as the layer tree for grouping and arranging strokes.

Any stroke can only belong to a single 2D layer. The selected layer is the active layer. Only one layer or group can be active at a time. When you draw, the new strokes are added to the active layer. By default the view order of the layers in the viewport is top to bottom.

Layers can be grouped using Layer Groups. A layer can only be in one group at a time. Layers can be moved into groups using drag-and-drop. Groups can be color coded with a color tag.

Every layer correspond to a channel in the Dope Sheet editor (in Grease Pencil mode). See Dope Sheet for more information.

Layers can also be used together with Modifiers to only affects part of your drawing. See Modifiers for more information.

Layers can mask other layers by enabling Use Mask (mask icon) or using the checkbox in the Masks panel header. See Masks for more information.

Tip

Sometimes the layers you are not working on can be a distraction in the 3D Viewport. Activate the Fade Inactive Layers overlay to control the opacity of the non-active layers.

Below the layers list there are additional settings:

Blend Mode

The layer blending operation to perform. See Color Blend Modes.

Opacity

Used to set the opacity of the layer.

Lights

When enabled, the layer is affected by lights.

Masks

Masks panel.

In Grease Pencil there are no special mask layers, any layer can act as a mask for other layers. The mask system is flexible enough to allow top-bottom and bottom-top masking.

Layers used as masks can use all the blend modes and different opacity values like any other layer.

Tip

If you want to make a full transparent masking you will have to set the mask layer’s opacity to 0.

The layer/s that will act as mask of the current layer could be added to the Mask list view.

In the Masks list next to the layers name there are two icons buttons that control common properties of the layer mask:

Invert (mask icon)

Inverts the mask.

Viewport/Render Visibility (eye icon)

Toggle layer visibility in the viewport and in render.
