## What it is
A ComfyUI custom node plugin implementing LayerDiffuse, enabling generation of transparent images with RGBA output and foreground/background layer separation using Stable Diffusion. It provides example workflows for generating foregrounds, blending layers, and extracting FG/BG from blended images.

## Use cases
- generate transparent PNG images with alpha channel from text prompts
- separate foreground and background layers from a blended image
- remove background from generated images
- blend a foreground layer onto a background layer
- create RGBA images directly in ComfyUI workflows

## When to choose
- you use ComfyUI and need transparent image generation or layer separation
- you want to generate images with alpha channels without external matting tools
- you need to extract or remove foreground/background from blended images

## When to avoid
- you use a different Stable Diffusion UI like A1111 or Forge (use the Forge extension instead)
- you need production-grade background removal for arbitrary photos rather than diffusion-generated images
- you cannot manage Python dependency conflicts around diffusers versions

## Facets
- artifact type: plugin
