Overview
Shapes with per-point feather and per-shape blend modes, rasterized by coverage so a soft edge is soft rather than stepped.
How to
- Draw in the viewer: click to place, drag to shape tangents.
- Feather per point where the edge needs it.
- Animate the shape's transform rather than every point when the whole thing moves.

Parameters
| Parameter | Type | Default | What it does |
|---|---|---|---|
| shapes | Shapes | — | The shapes, as the node stores them. Draw and edit in the viewer. |
| layers | Layers | — | The layers the shapes live on — each with its own transform and blend. |
| feather | Float | 2.0 | Default feather for new shapes, in pixels. |
| opacity | Float | 1.0 | Default opacity for new shapes. |
| invert | Bool | false | Swap inside and outside: 1 − the result. |
| output | Choice | alpha | alpha writes only the matte (a mask to carry on a plate); rgba fills colour too (a viewable grey). alphargba |
| format_width | Int | 1920 | Width in pixels. |
| format_height | Int | 1080 | Height in pixels. |
| disabled | Bool | false | Bypass: the node passes its first input through untouched (D in the graph). The knobs keep their values for when it comes back. |
| label | Text | A note shown under the node in the graph — what this node is FOR. Never affects the render or the cache. |
