The Layer Masks feature allows you to control the transparency/visibility of a layer using various mask types. It's a non-destructive way to hide or reveal parts of a layer.
Masks works on all layers types- however currently each layer can only have one mask (image mask)
Support for other Mask types such as: Vertex, Gradient and procedural textures may be supported in the future

This will create an image for the mask- prompting if you would like the mask to be show all or Hide all initially.

Image Masks are exclusive to a material. This means copying and pasting a layer as a Linked Layer, does not copy the image mask as well.
