Sketchbook Pro on macOS
The new release of Sketchbook Pro v9 on macOS is available now on the Mac App Store!
This update updates color features, UI improvements and much, much more.
Masking blend modes
There are two masking blend modes:
Alpha mask masks out the transparent areas of a layer. Areas with pixels will define the visible region of the layers below.
Inverse alpha mask reverses the effect, and painted areas are masked out. The transparent portions of the layer define what remains visible.
Masking blends work the same as other blend modes - their effect applies to all the layers below; they can be used in layer groups to help define/control which layers are affected; and they can be applied to a group, allowing you build up a mask using different layers as components.
