Install the sd-webui-controlnet extension to enable guided image generation.

Why

  • Allows using reference images, sketches, or depth maps to guide generation
  • Enables img2img workflows where a rough sketch gets refined into a polished image
  • Essential for consistent style and composition control

Steps

  1. Install via Extensions tab → Install from URL
  2. Download required ControlNet models (at minimum: canny, depth, openpose for SDXL)
  3. Verify it works with a test generation
