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.
- Black mask — starts fully hidden; reveal by painting white or with a generator. Good for adding detail to specific spots.
- White mask — starts fully shown; carve away with black.

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:
| Entry | What it adds |
|---|---|
| Paint | Hand-painted grayscale (brush / fill directly on the mask). |
| Fill | A constant level, or a value sampled from a source. |
| Generator | A procedural mask from the mesh — see Generators. |
| Filter | Adjusts the result so far — see Filters. |
| Anchor | Marks 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.
