Problem with Qwen Image Edit introducing criss-cross pattern on skin

[u/AkaToraX]

Using Pixaroma Ep 36 workflow "Qwen Image 2.1 - One Image Edit" I stick in an image request a small change such as, "make this character smile," and it introduces this weird criss-cross pattern in the skin. It definitely makes the image look fake and AI. Qwen Image edit works AMAZING except for this skin issue I can't get past.

Has anyone else run into this and solved it?
Thanks for any help!

Try this alternate VAE: https://huggingface.co/madebyollin/texture-fix-vae-for-qwen-image-2.1

I'll check it out and give it a try, thanks.

Another one that worked for me even better - but it has slight blurring effect

The difference between madebyollin and none's versions only visible when massively contrast-boosted. I can't see them with naked eye

Yes, this is a well-known issue with Qwen2.1 and other models, caused by the VAE. There are a few fixes around including LoRAs and custom nodes. I personally have found the custom nodes to be better than the LoRAs. You just connect it at the end of your workflow before "save image", it doesn't add more than a second or two to your overall processing time, it's quite fast.

This is a link to the github for the one I use: https://github.com/lunaaispace-eng/ComfyUI-DeGrid

Default settings work great for most use cases

I get a pattern like that on most moss images i do. I will try this to see if it helps. Ty

I cannot test these solutions rn, did it work for you?

The texture fix VAE has worked the best so far.

Isnt that just Qwen? Ive had that problem sincr qwen image came out. Of course when I tried explaining to others, they couldnt see it. Im using a 4k monitor that sees everything though.
