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.
RF-Inversion can also be used to stylize images.
Use this workflow to style images.
RF-Edit (Unsampling from RF-Solver-Edit)
RF-Edit is an alternative way to edit images. It may suit some use cases better than RF-Inversion and I recommend trying both.
Use this workflow for RF-Edit.
Regional prompting allows you to prompt specific areas of the latent to give more control. You can combine it with Redux, but Redux is so powerful it dominates the generation. This implementation is based on InstantX Regional Prompting.
Use this workflow for regional prompting.
There are two nodes for Perturbed Attention Guidance (PAG) and Smoothed Energy Guidance (SEG) that can add detail to images.
