ComfyUI: Style transformation and line art conversion

ComfyUITry it →Watch full video →pixaroma ·

Demo summary

The creator demonstrates transforming a portrait into a watercolor painting and converting a 3D-style bunny into a line art illustration using specific style prompts.

Step-by-step

  1. Start the prompt with 'transform to' followed by the desired art style (e.g., watercolor painting, oil painting, or line art).
  2. Include phrases like 'maintain original composition, pose, and facial features' to preserve the source image structure.
  3. Run the workflow to generate the transformed image.
  4. Change the seed if you need to generate a different version of the result.
  5. Upscale the final image to add more details.

Options

  • Transform images into coloring book pages.
  • Perform the process in reverse by providing a sketch/line art and prompting for colors and style.
  • Find or train a LoRA for specific art styles the base model doesn't know.

Watch out for

  • The output is not perfectly identical to the source; facial shapes may become more rounded or vertically squashed.
  • The seed is fixed by default, so you must manually change it to get a new variation.

Tips

  • Use Adobe Photoshop or Illustrator to refine the generated illustrations for a professional finish.
  • Use Flux for these tasks as its context handling is particularly effective for maintaining similarity to line art.

Highlights

“you can create a nice illustration way faster than doing it manually”
