What types of objects can be swapped using this workflow?

The workflow can swap any object as long as the replacement object is compatible in size and perspective with the original scene.

Can this workflow handle multiple images at once?

Yes, by using the BatchImagesNode, you can process multiple images simultaneously, making it ideal for bulk editing tasks.

Is the original image quality preserved after editing?

Yes, the Flux2MaxImageNode is designed to maintain high image quality, ensuring that the edited image is as sharp and clear as the original.

Do I need any specific skills to use this workflow?

Basic familiarity with ComfyUI workflows is helpful, but the step-by-step process is straightforward enough for beginners to follow.

FLUX.2 [max]: Object Swap - ComfyUI Workflow

The FLUX.2 [max]: Object Swap workflow is designed to seamlessly replace objects within images while preserving the overall scene consistency and quality. At the heart of this workflow is the Flux2MaxImageNode, which leverages advanced image processing techniques to ensure precise object swaps. This workflow is particularly useful for tasks such as product photography and furniture swaps, where maintaining the integrity and aesthetics of the original image is crucial.

The process begins with the LoadImage node, which imports the image you wish to edit. The Flux2MaxImageNode then performs the object swap by identifying and replacing the target object with unmatched precision. The GetImageSize node ensures that the dimensions of the images are consistent throughout the process, while the BatchImagesNode allows for processing multiple images simultaneously, making it efficient for bulk tasks. Finally, the SaveImage node outputs the edited image, ready for use in various applications.

# Install (beta)
pip install comfy-sdk        # Python
npm i @comfyorg/sdk          # TypeScript

# Run "FLUX.2 [max]: Object Swap" (Python)
from comfy_sdk import Comfy

client = Comfy(api_key="comfyui-...")

# This workflow, exported in API format (see note below)
wf = client.workflows.from_file("api_bfl_flux2_max_sofa_swap_api.json")

asset = client.assets.from_file("input.png")
wf.set_input("10", "image", asset)  # LoadImage

job = client.run(wf)
for output in job.get_outputs("6"):  # SaveImage
    output.to_file(output.name)

The SDK takes a workflow in API format: open this workflow in ComfyUI and use File → Export Workflow (API). API access requires a Comfy Cloud plan with an API key. SDK docs · Get an API key
