Compositing

These nodes turn ComfyUI into a Photoshop-style layer stack: a background, layers on top with blend modes, opacity, fill, masks and clipping, groups, and a final flatten. They are meant for deterministic finishing passes after generation or retouching, where you want to adjust one layer without redoing the rest. Pyramid Blend is the odd one out: it joins two images through a mask so the seam disappears.

  • Layer Stack Start

    Makes the background layer of a stack from an image.

  • Layer Add

    Adds a layer with blend mode, opacity, fill, mask and clipping.

  • Layer Group

    Merges a sub-stack into one layer, like a Photoshop group.

  • Layer Flatten

    Renders the stack back into a normal image.

  • Pyramid Blend

    Seamless two-image composite through a mask using multi-band blending.
