ComfyUI-Fluxtapoz (WIP)

A set of nodes for editing images using Flux in ComfyUI

Examples

See example_workflows directory for examples.

No ControlNets are used in any of the following examples.

Rectified Flow Inversion (Unsampling from RF Inversion)

Admittedly this has some small differences between the example images in the paper, but it's very close. Will be updating as I find the issue. It's currently my recommended way to unsample an image for editing or style transfer.

It can also be used to mix or style images (although I'm still working out the settings for this)

Node Parameters

Outverse Flux Model Pred Node

• Ensure "reverse_ode" is set to True on the "Outverse Flux Model Pred" node. Sometimes when users upgrade this repo it doesn't load the workflow correctly.

Flux Reverse ODE Sampler

• latent_image -- the image to guide the sampling
• start_step -- the step that the sampler starts guiding the sampling towards the image in "latent_image"
• end_step -- the last step for guiding the sampling (not inclusive)
• eta -- the strength of the guidance

Flux Forward ODE Sampler

• gamma -- the paper leaves this at 0.5, but is similar to eta in the Reverse sampler

Guidance Suggestions

• For sampling normal flux guidance works (~3.5)
• For unsampling I find low values such as 0 or 1 work best

Inverse Noise (unsampling)

Inject Inversed Noise

See example workflow for how to use this one. It's similar to inverse noise/unsampling, but has better adherence to the input image.

Reference Sampling (WIP)

This is a different implementation than TDS' and is experimental. Some results can turn out blurry and it is difficult to control. See the updated workflow json for the latest test.
