ComfyUI: Iterating and upscaling character variations

Demo summary

The demonstration shows how to refine specific outputs by adjusting prompts (e.g., 'extremely angry') and batch-running upscaler nodes to finalize the character sheet.

Step-by-step

  1. Plug the target image into the router nodes for description and generation.
  2. Review the generated description (e.g., skin tone, face shape) to ensure accuracy.
  3. Select only the image generation nodes first to preview variations.
  4. Adjust the text prompt with specific modifiers like 'extremely angry' to refine expressions.
  5. Run the model to generate the new variations.
  6. Select all upscaler nodes once satisfied with the previews.
  7. Execute the upscalers to finalize the character sheet.

Options

  • Crop images within the workflow if the framing is slightly off
  • Run specific selected nodes instead of the entire workflow

Watch out for

  • Ensure the prompt has enough tokens to specifically trigger the desired look or expression

Tips

  • Select only image generation first rather than upscaled versions to save time during iteration
  • Use more descriptive tokens like 'extremely' to push the AI toward more distinct character expressions

Highlights

it was like under two minutes with every single case
