Reproduction Steps

nunchaku imagedit 2509 fp4

[ZaneA]

This is a bug in the ComfyUI node due to recent ComfyUI updates, nunchaku-ai/ComfyUI-nunchaku#725

Replace custom_nodes/ComfyUI-nunchaku/models/qwenimage.py with the following https://github.com/nunchaku-tech/ComfyUI-nunchaku/blob/2f991a44e6e20cf1ca04f2ab81df529966b2fe82/models/qwenimage.py and it should work again

[MoonMoon82]

@ZaneA This file does definitely not work. It's not causing to crash, but the output images only have slight similarity to the input images.

[ZaneA]

@MoonMoon82 with the new 2511 edit model others have reported similar issues to what you're describing, in that case you may need to add the FluxKontextMultiReferenceLatentMethod node with the index_timestep_zero value to your workflow (see https://old.reddit.com/r/StableDiffusion/comments/1pu354f/how_to_use_qwen_image_edit_2511_correctly_in/).

Not sure if that also applies to 2509 after the ComfyUI update, but the file replacement worked in my case and solved this particular bug.

[SveSop]

@ZaneA Even tho this hack seems to work to get the "old" nunchaku 2509 edit modes with the various lora's (relight and whatnot), the lora's seem to throw massive amounts of warnings like this:

If i understood it correctly, the qwen image edit 2511 had these "built in", so i suppose its just to wait for a tuned svdq-int4_r128-qwen-image-edit-2509-lightningv2.0-4steps.safetensors version of 2511?

This is a bug in the ComfyUI node due to recent ComfyUI updates, nunchaku-tech/ComfyUI-nunchaku#725

Replace custom_nodes/ComfyUI-nunchaku/models/qwenimage.py with the following https://github.com/nunchaku-tech/ComfyUI-nunchaku/blob/2f991a44e6e20cf1ca04f2ab81df529966b2fe82/models/qwenimage.py and it should work again

Thanks man @ZaneA this works for me.
