The Luma Image to Image node allows you to modify existing images based on text prompts using Luma AI technology, while preserving certain features and structures from the original image.

​
What Luma Image to Image is good at

  • Prompt-driven image editing: Modifies existing images based on text prompts while preserving certain features and structures from the original
  • Changing objects and shapes: The node works well for changing objects and shapes, though it may not be ideal for color changes
  • Adjustable input influence: The image_weight parameter controls how strongly the input image shapes the result, with lower values staying closer to the original

Make sure your ComfyUI is updated.Workflows in this guide can be found in the Workflow Templates. If you can’t find them in the template, your ComfyUI may be outdated.If nodes are missing when loading a workflow, possible reasons:
  1. You are not using the latest ComfyUI version (Nightly version)
  2. Some nodes failed to import at startup
