Mask basics

Adding a mask

Add a mask to any layer. The mask is grayscale: white shows the layer, black hides it, grays are partial.

The mask stack

A mask isn't just one image — it's a small stack of entries evaluated top-to-bottom, so you can combine procedural and hand-painted input:

EntryWhat it adds
PaintHand-painted grayscale (brush / fill directly on the mask).
FillA constant level, or a value sampled from a source.
GeneratorA procedural mask from the mesh — see Generators.
FilterAdjusts the result so far — see Filters.
AnchorMarks a point in the stack that other entries can reference (advanced).
Each entry has its own blend mode and opacity against the result so far, so you can layer a hand-painted touch-up on top of a generator, for example.
