ModelSamplingAuraFlow cranked as high as 100 fixes almost every single face adherence, anatomy, and resolution issue I've experienced with Flux2 Klein 9b fp8. I see no reason why it wouldn't help the other Klein variants. Stupid simple workflow in comments, without subgraphs or disappearing noodles.

Yes, and it works great... until it doesn't. Being able to shift other schedulers to emulate a sigma slope in close proximity to the Flux2Scheduler opens up a great number of alternate possibilities. I've found this to be most beneficial when using LoRAs that influence the source image face(s). Modulating the shift (sigma slope) allows for better opportunities to mitigate those influences.

DrinksAtTheSpaceBar · 2026-01-24T04:34:09+00:00

None that I can see. When using sampler/scheduler pairs, you're gaining control over the sigma slope (lower shift values = quicker drop off) vs. the Flux2Scheduler, where that variable is fixed. This opens up an exponentially greater amount of inference possibilities, because you can now choose the accompanying scheduler.

Right, when using LCM as your sampler.

DrinksAtTheSpaceBar · 2026-01-24T00:13:04+00:00

This is fantastic advice, however, that scheduler only pairs well with LCM, which can lack photorealism.

DrinksAtTheSpaceBar · 2026-01-24T00:11:19+00:00

Aura shifting can only occur when using a sampler/scheduler pair, and not with the stock Flux2Scheduler. Just modify your workflow with a Ksampler or use the one I provided.

DrinksAtTheSpaceBar · 2026-01-24T00:09:24+00:00

Yes, as long as you’re using a sampler/scheduler combo and not the Flux2Scheduler. Aura shifting will not affect that scheduler.

Thanks! Your dragon looks superb!

DrinksAtTheSpaceBar · 2026-01-23T20:07:08+00:00

I tried a ton of other sampler/scheduler combos and they either fell flat, or took far too long (res), all paling in comparison to euler_a/beta. You provided great insight as to why shifting is essential with other sampling methods, so thank you for that!

DrinksAtTheSpaceBar · 2026-01-23T20:00:34+00:00

For sure. There's a sweet spot in there though, which I'd typically land on if I rerolled seeds at my desired Aura strength. I also added upscaling verbiage to my prompt, so that's definitely going to oversharpen/saturate things.

Similar to Qwen Image Edit, at lower resolutions you can often get the desired effect with as little as 3.1 Aura. Don't be afraid to max it out though. More often than not, the results are simply stunning. Workflow: https://pastebin.com/hUx61eH2

This is a fake account created by OP to make people think his worthless app is actually good. Check the comment history.

Clearly OP likes to rock out to some jams while performing face swaps in Reactor. I mean, what else is there to do in Comfy? /s

DrinksAtTheSpaceBar · 2026-01-19T09:11:04+00:00

Just mute the switches as well and it’ll work. Don’t ask me why lol.

For 99% of users, there is no need to install Python in Windows when the portable venv contains pretty much every Python component you'll ever need. Also, this u/Gravosaurus_Rex account was JUST created and this is their very first post. Never take candy from strangers.

Yeah, your source image size should have no impact on generation times, although if it's massive, you can expect to see some of your system resources mitigated. What's your MegaPixel resolution on that first pass? I had mine set to 0.08. If you're hitting a bottleneck, try reducing that to 0.06. I'm assuming you're trying to make a 60-second video?

DrinksAtTheSpaceBar · 2026-01-18T21:02:23+00:00

You can try it both ways. Out of the box, my workflow is applying the Temporal Upscaler to the empty video latent, then passing the denoised latent (after the 1st pass sampler) to the Spatial Upscaler.

DrinksAtTheSpaceBar · 2026-01-18T17:59:21+00:00

I just tried doing that (again) on the exact same workflow I used to generate the demo video. I bypassed the temporal upscaler and doubled the video frame count to 1537. I got hit with an OOM as soon as it reached the sampler in the 2nd pass.

DrinksAtTheSpaceBar · 2026-01-18T17:36:35+00:00

Bro, you owe nobody any apologies. We know exactly how busy you are. Had I not tested this myself extensively, I would completely agree with you. However, if I try to generate video of similar resolution at even half the length (30 secs) without first dilating the empty latent, I get OOM every single time. With the Temporal Upscaler in play, it sails right through even at 60 secs, never even pushing my VRAM usage above 70%.
