Basic Info
This is not going to be a big article, I just wanted to share some experimentation which gave some nice upscale details with Flux. Workflow .json file and Images are in the zip. This assumes you have a basic working knowledge of Comfyui. I'll add info at the end for custom nodes. You should be able to drag the upscaled image or Screenshot (from the zip only) or .json file into Comfyui to recreate the node setup. Then go into Comfyui Manager and click on "Install Missing Custom Nodes" I included the option to add Loras in case you want to make some changes to the original, you can also look at my setup to see how I made some prompt adjustments to the tagger for additional customization.
Custom Nodes
> Anything Everywhere
> Rgthree
> Ultimate Upscale SD
> WAS Node Suite (Only used for image save in this setup, you could skip installing this custom node and swap with a standard Comfyui Save node, but I highly recommend having WAS Suite)
> Stability Comfy Nodes (For Get-Image SIze)
> Miaoshouai Tagger (An awesome image tagger)
> Flux Model
> Flux Clips : clip_l and t5cxxl
