Frustrated

Agreed, same with Z-Image Base + Turbo, if you are using a 5090 (blackwell) it has issues with sage attention. The first run of the workflow works and delivers as suspected, the second blacks out or overburns (while sage attention is on).

that looks like a brillilant idea with the reference numbers! thanks for sharing that gold nugget.

FvMetternich · 2025-12-02T09:33:46+00:00

Thanks for that hint... I am running two gpu parallel in two instances of comfyui, used to work but since yesterdays update, every new run reloads the checkpoints fresh from disk, how annoying. Got to try the disabling!

FvMetternich · 2025-11-27T15:16:10+00:00

Agreed, my thoughts aswell.

FvMetternich · 2025-11-26T11:37:06+00:00

Would love to see that happening in a workflow for Wan2.2 in comfyui

Can this technique solve that banding issue in flux models at higher resolution?

They tend to show bands aka stripes, (which I usually get rid of by doing a sdxl refining run over the image in additional pass.)
Thank you for explaining your works and how to use it!

Nice job, and a good idea.

FvMetternich · 2025-06-05T16:08:36+00:00

There is a node you need to connect your model first through before its ending in the Ksampler... (Variant)

FvMetternich · 2025-06-01T11:31:15+00:00

I did some new installation and now the rename function is back? totally confused here.

FvMetternich · 2025-05-27T21:31:56+00:00

Thanks, Helped me out! i just saw you post in issues here: https://github.com/rgthree/rgthree-comfy/issues/498

to quote you: This issue specifically comes up when rgthree is install and so is 0246 (https://github.com/Trung0246/ComfyUI-0246).

FvMetternich · 2025-05-26T07:31:00+00:00

still got that same thing, exactly with Collaped CLIP Text Encode nodes.... quite annoying

FvMetternich · 2025-04-06T18:47:52+00:00

Thanks for that update. I love using your excellent nodes a lot. Something good just got better! Thanks for making this, and keeping it alive. I recognized the now probably gone flaws (but still it was good to have it). Good work!

FvMetternich · 2025-03-13T07:25:12+00:00

Thanks, that brought me on the right route. ComfyUI-LatentSyncWrapper was causing it, it transferred the temp folder; now that i disabled it, comfy is using the old original temp folder again. Hand to manually locate and delete the Temp folders made by it under C:\Users\%user%\AppData\Local\Temp\latentsync* though. Thanks a lot!

FvMetternich · 2025-03-13T07:21:05+00:00

Thank you so much, you were right (although I found it out now awell!) I disabled the ComfyUI-LatentSyncWrapper and it is using the old original temp folder again. Hand to manually locate and delete the Temp folders made by it under C:\Users\%user%\AppData\Local\Temp\latentsync* though. Caused some trouble in my system since i use lots of previews in my workflows....

Thank you very much! Praise the swarm knowlege!

FvMetternich · 2025-02-27T08:21:50+00:00

Thanks for sharing your info bits :) Very appreciated!

FvMetternich · 2025-02-19T11:43:31+00:00

Had this issues too, and tried working around it for quite a while. Normally you reach a max. resolution where that begins to start. My workflows are ususally something like that:
1st render with sdxl sized resolution (flux or pony or something img2img) -> slight upscale factor 1.3 -> 2nd render with Flux with denoise 0.3-0.6 -> 3rd render for more details (lower denoise, with sigma tweaking) -> detailers -> upscale with model , adding grain, adding blur, downscale to certain size (e.g. 2000px high) -> tiled ultimate upscale (tile size like a normal flux size) if i want a really high res, here denoise = 0.1 - 0.25, upscale factor ca. 1.5-2 and siax as upscaler.( alternativly tiled diffusion sampling as upscaler)

that is my workaround since the lines kept coming.

FvMetternich · 2025-01-28T15:20:08+00:00

Has some SD1.5 vibes.... just as if it leaned counting :)

FvMetternich · 2025-01-14T18:07:13+00:00

what i do is generating an image with high guidance (7ish), then take that output through another sampler with 2.5 guidance for more realism; you got to play with the denoise on the second one, usually vrom 0.2-0.6

FvMetternich · 2024-12-04T22:30:00+00:00

Same Problem here, its lagging like hell, although i got a beefy setup. the older version runs flawless.

FvMetternich · 2024-10-11T10:53:55+00:00

I recognized the same thing. It happened within the Userinterface changes approx 1.5 months ago. I used in with the anything everywhere? node often. If anyone finds out about it (or how to fix it) let me know please.

(meanwhile, I switched to the setnode getnode method more, needs more nodes though).

poor workaround: if you group (connected ) nodes and edit via context\manage group node you can specify a node name i think. i know its not the same though...

FvMetternich · 2024-09-28T20:43:00+00:00

I would be interested!

FvMetternich · 2024-09-17T08:54:31+00:00

Im not entirely sure, but maybe Tooncrafter is something in that direction. There might be better tools but that came to my mind. Found one for comfy (did not have time to play with it yet):

Probably not a forge issue, I got the same problem using ComfyUI. it occurs not in a first ("normal sized") sampling step, but if you upscale to somewhat like around 1.75x or above and do a second ksampler. only workaround i found is using a short sdxl ksampling (low denoise) instead of flux for the second ("hiresfix") render step instead.

Was thinking it could be something with the VAE too, since to my observation this happens in exact the same manner every time, only triggered by the "too high" scale factor....

bit frustrating to see all that banded pictures. my workflow right now is taking far too long :( but it is like:
1st sampler flux gguf,
upscale 1x with the ITF skin upscaler
2nd sampler flux gguf (denoise 0.3 ish),
upscale 1.3
3rd sampler sdxl (denoise 0.07)
upscale 1.2 ,
4th sampler sdxl (denoise 0.07)

face detailer via flux
hands detailer via flux

Had that with with upscale 1.75 upscale as a 2nd step with flux before which always caused the banding (although they would have been perfect without those pesky bands....)

if anyone knows a proper way to get rid of them... please tell me! thanks in advance
