A set of nodes for editing images using Flux in ComfyUI
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.
Use this workflow for RF-Inversion.
It can also be used to mix or style images (although I'm still working out the settings for this)
- 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.
- 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. The paper does not decrease this below 0.7
- gamma -- the paper leaves this at 0.5
- For sampling normal flux guidance works (~3.5)
- For unsampling I find low values such as 0 or 1 work best
- Blurry Results -- try lowering denoise to around 0.9 on the sampler (not the unsampling sampler) or increase the unsampling steps
- Not following edits -- try fewer steps (change start/end step) or lower eta
See example workflow for how to use this one. It's similar to inverse noise/unsampling, but has better adherence to the input image.
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. Results are typically not good.
