My high level custom Krea2 workflow. Single/2Pass, lots of options for controlling bypass, negative prompts, equipped with text2image and image2image Inpainting modes.
See it in action in my character creation tutorial video:

Disclaimer: There was an update to comfyUI two days ago that broke NegPip/Enhancer (two completely optional nodes in this WF). If you update comfyUI as of today (7/22/26) it'll work again, and it'll also work if you have an older frontend too.
This is why I keep auto update off
@pogo sadly as a content creator I'm not allowed to be on an outdated comfyUI. I have to vet everything for current versions and it's a huge pain in the ass to be perfectly honest.
@foxydits fyi it seems like the workflow is not what you showed in the video, so some stuff isnt there. like the prompts for poses. not a big deal.
@pogo That's in my Flux Klein 9b workflow. You can't use those pose prompts in Krea2, it's not an instruction based image-edit model. You would CREATE your character in Krea, then take that character gen to Klein 9b, where you would copy/paste those pose prompts. It's pretty clear in the video I thought! But maybe you are skipping around or something.
Getting the following error when negpip is enabled:
"TypeError: krea2_negpip_wrapper() takes from 4 to 6 positional arguments but 7 were given"
It was a glitch in one of the comfyUI frontends recently. You just have to update comfy... & make sure the node is up to date too for good measure.
@foxydits Still no dice, unfortunately. Might be an issue on my end (I'm running Python 3.12 on Linux, so maybe one of those things could be a problem). Will keep updating periodically:-)
@Hookflash Yeah... might have to run that update_comfy_and_python_dependencies.bat file this time around I'm afraid. I have to run it all the time now because as a content creator I can't be using old versions of anything really, it's not so bad. Tbh you can just disable the negpip option if you don't wanna do that. The wf will work fine with it turned off in the options.
For anyone else still having this problem, changing ComfyUI to latest fixed it for me. It's still broken on the stable release.
EDIT: I went back to stable because latest was causing bugs in other node packs I use. Now negpip works fine. So there was some sort of problem with the environment that got fixed by the rollback.
This workflow is easy to use and produces great results with very little effort. I'm definitely going to check out your LTX workflows.
Because comfyUI update bugs out the node, for any of you experiencing issues with the Negative guidance node, use this fork to resolve the error:

Or just wait til comfyUI fixes it.
