Maybe this workflow is to basic for this lofty place. However, I struggled quite a while with a good SDXL inpainting workflow. Before inpainting it will blow the masked size up to 1024x1024 to get a nice resolution. The blurred latent mask does its best to prevent ugly seams.
Concept:
Generate your usual 1024x1024 Image.
Upscale (I go for 1848x1848 since somehow results from a 1.8x resize in my upscaler).
Load to upscaled Image to the workflow, use ComfyShop to draw a mask and inpaint. A transparent PNG in the original size with only the newly inpainted part will be generated.
Layer copy & paste this PNG on top your original in your go to image editing software. Save new Image
Insert new Image in workflow again and inpaint something else
rinse and repeat.
The workflow includes optional modules for LORAs, IP-Adapter and ControlNet.
WARNING: Don't install ALL the suggested nodes from ComfyUI Manager's "install missing nodes" feature!!! It will lead to conflicted nodes with the same name and a crash. Just install these nodes:
Fannovel16 ComfyUI's ControlNet Auxiliary Preprocessors
Derfuu Derfuu_ComfyUI_ModdedNodes
EllangoK ComfyUI-post-processing-nodes
BadCafeCode Masquerade Nodes
Jcd1230 Rembg Background Removal Node for ComfyUI
Nourepide Allor Plugin
Suzie1 ComfyUI_Comfyroll_CustomNodes
cubiq ComfyUI_IPAdapter_plus
rgthree rgthree's ComfyUI Nodes
Additionally, I suggest Mangler's FTW ComfyI2I as it provides a nice masking editor by right clicking on the loaded image.
