Compositing

The compositing category turns ComfyUI into a Photoshop-style layer stack with blend modes, grouping, and flattening. These nodes are meant for deterministic finishing passes after generation or retouch work is done.

• N-24 Layer Stack Start — Starts a LAYER_STACK from a background image.
• N-25 Layer Add — Adds a masked layer with opacity, fill, blend mode, and clipping options.
• N-26 Layer Group — Flattens a sub-stack into a grouped layer for nested compositing.
• N-27 Layer Flatten — Renders the layer stack back to a final image.

Flagship pages: N-29 Alpha Matte Extractor, N-33 Mask Edge Smoother, and N-10 Face Detect.
