Layer list with masked layers.
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 mask can use all the blend modes and different opacity values like any other layer.
Note
If you want to make a full transparent masking you will have to set the mask layer(s) opacity to 0.
Masks list view.
The layer/s that will act as mask of the current layer could be added to the Mask .
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)
视图/渲染可见性(眼睛图标)
