does anyone know how to paint (and animate) a mask within the new Grease Pencil (Blender 2.8) ?
I guess that it should be possible to either define a Grease Pencil layer as mask; or to use an holdout material or something ?
Thanks !

Using Subtract as a Blend mode for a Grease Pencil layer acts just like a mask:
Subtracted layers will act as holdout for every other layer that is listed below them, but regardless of their view-depth (layers in front are masked out too). Layers in other GP objects are not affected

$\begingroup$ Seems perfect but it is not working here (2.8 beta), don't know why ? I use a black material like you, my GP layer blend mode is set to "substract" too. And I get this : imgur.com/a/rM5Rxky $\endgroup$ – gordie Dec 27 '18 at 17:49

$\begingroup$ is it the top layer and in the same object? it should work.. keep in mind the feature was added in the last month so you need an updated beta $\endgroup$ – Nicola Sap Dec 27 '18 at 17:59

$\begingroup$ Got the last nighlty. Maybe you need a background color for this to work ? (not working on transparent) ? $\endgroup$ – gordie Jan 2 '19 at 17:34

$\begingroup$ The contents of a subtract layer become visible wherever they don't overlay with the contents of other layers. This is quite different from the behaviour of masks in other graphics/animation software. Is there any way to have the contents of a masking layer be invisible in all cases, but still mask other layers when they overlap? $\endgroup$ – bitbutter Apr 18 '19 at 11:30
