I really appreciate the fact that you're giving your workflows away for free. Yesterday I deleted the folder of my Comfy install, forgetting that I had a Workflow folder in it, with everything gathered over the past months and the ones I did myself. I've made the mistake of clicking on update_comfyui_and_python_dependencies instead of doing the proper update. It messed up my whole install. Krita and the stable diffusion plugin stopped working because of a flash attention error. Anyway, I nuked the folder, but before that, I made a second install from scratch in a new folder. And deleted the old one, forgetting to move all the workflow files. I'm glad that we have access to almost all of your workflows, thank you for that. PSA for anyone reading this. Never keep models, checkpoints, and the workflows in the Comfy folder (or auto1111 for that matter). Have the most important folder on a separate disk or dedicated folder outside of the install folders. And you like them with symlinks. By doing that, a git pull or deleting the installation folder of a1111, my mistake or not, will not delete the important files.
As @TransformXRED said, it's really nice of you to provide these workflows to the community at large rather than behind a Patreon paywall. (Which I will definitely consider joining....being a fellow lover of "Dad jokes"!) I usually am able to run (barely) the f.8 model, as I have VRAM of 12GB, so hopefully this will work for me without completely shutting down my machine!
I have been simply using a separate workflow that takes an image as input, then upscaled and converted to latent. So copy-paste from one workflow to the other. Works pretty well if you're just looking to improve quality and upscale very lightly.
thanks great video. what i like to do is, setting the tile size higher so that the image size isnt a multiple of the tile size (i.e. for 2048x2048 images something like 1256x1256 tiles) to create an overlap (or increate the padding option, but this doesnt work as good). most of the time the blending of the node removes the seams (if the denoise isnt insanly high).

Thank you for all these detailed explanations! Would it be possible to do a video about creating consistent characters using Flux? I'd love to see your insights on that.

For the live preview go into Manager and on the top left there's a drop down called Preview Method, choose one of the options on there. I could be wrong but I think the Progress bar is part of the Crystools Custom Node as it shows system usage as part of that as well,
Anyone have any idea about this error? "ValueError: not enough values to unpack (expected 2, got 1)" I tried connecting it to the flux model after a facedetailer node
hey Sebastian thanks for the nice tutorial! For some reason NF4 is 3 times slower than Flux Schnell, do you maybe have something in mind i couldve done wrong?
is this possible with just the load diffusion node for just Flux1 dev? really wanted to use this workflow with my loras, currently my loras tend to make the image a little blurry, i tried integrating the lora stack loader RGthree but i get an error at the custom sampler. think its cuz the loras are trained on Flux 1 dev, and not Flux NF4. or at least thats what chatgpt says lol. any advice or suggestions so i can use multiple loras with this upscaler workflow?
I must be doing something wrong. I updated Comfy, but when I load your workflow, the checkpoint loader is red.. can't install it as a missing node either. Then when I replace it with a regular checkpoint loader, I get a bunch of errors when I try to run it. I put the model in /models/checkpoints, although my fp8 schnell and dev are in /models/unet. Putting it in the unet folder and using the fp8 model workflows to load the model also gives me errors. Pretty sure I downloaded the whole model without problems as well.
Hello! First of all, thank you so much for your videos AND your written tutorials (I usually prefer reading to go over it a couple more times) This is so helpful and I appreciate the time you put into everything! My question: I did notice that negative prompts are not used in your workflow. Is this because it is not a thing with Flux or just because you dont use them?
Great tutorial! I am interested on your take on doing a latent image upscale, followed by a sampler. I know that beyond a point you will hit memory issues, but before you get that point, wouldn't it be better than ultimate upscale?
Something changed in the last couple of days. I can't use the nf4 models in comfyui on my rtx 2080 super 8GB anymore. Getting only OOM, even with --lowvram. So much for this being the "low vram" model, while I can still use the fp8 ones, but you know, they are freaking slow on a GPU like this.
I have the same problem on 1060 3GB VRAM: torch.OutOfMemoryError: Allocation on device It looks like SamplerCustomAdvanced might be causing problems. Any way to replace it with another node?🤔
Ohh, I do like those performance bars you have in your main menu.. what add-on is that? Time to give these models a go later, thanks for the walkthrough!
@@SpikeColgate I use the siax one we see in this video. I could not tell you which one is best. I just know that it bring a lot more details than 4x ultrasharp.
Did they fix the contrast issue in sd upscale? I stopped using it a while back as all my upscaled images came out slightly whiter than the image input, like the contrast was tweaked and washed the colours a bit.
put into the folder like your guide said but when I load json file it says "When loading the graph, the following node types were not found: CheckpointLoaderNF4 UltimateSDUpscale Nodes that have failed to load will show as red on the graph." I also cannot update all on comfy manager, it gives an error message saying it cannot update, any idea whats going on?
Ooops...forgot to ask. I tried loading my upscaler into an Models/ERSGAN folder, but it's not showing up in the interface. Any ideas? Am I putting it in the wrong place?
@@sebastiankamph lol true. As for sd3, is it base sd3 or a fine tuned one? Cause I tried it with base sd3 (when it first came out) and compared it with my fav sd1.5 (with some embeddings), and to me it felt like sd1.5 was better. Since then I didn't feel like getting any news on sd3 (I also lost my hope on new open source models until flux came out)
Amazingly easy to follow tutorial as always! Noob question. Two in fact. 1: Would it be possible to upload an image to this workflow rather than generate one with text, if so how? and 2: What if you wanted to upscale multiple times the way that was shown here but only realised after you had upscaled once already? What I mean is could I add a second upscaler and THEN have it continue the process of upscaling that existing image or would I need to start the whole process again (essentially losing that image) by generating a new one?
Thanks Sebastian for what you publish in your channel. One question, if you just download “Flux Upscale” to the PC, can it run as a separate module without having Flux installed? Is there a link to run “Flux Upscale” online without downloading it? Thanks.
Hi Sebastian, thanks for your videos! Can you please make a tutorial on flux face swap? I don't even know if it's a thing since flux is so new. Thanks in advance
Please help. Your all videos got same description and links. I need to try this as well. Please tell me or can you send me link. What is different comfy ui and pinokio version what i need to install. Please refer your install video of comfy. Please
Quite new to comfyui here, anybody knows how to control the image generator and the upscaler separately? Maybe I don't understand how this is supposed to work but I would love to just generate images and trigger the upscaler on that specific image when I want. Currently it is running the full process on every iterations so it takes quite some time considering not all results deserve an upscale. Any tips welcome :)
So I couldn't get the flux LORAs working with the v1 but v2 they seem to be working fine or am I crazy? --edit: apparently they just don't do anything atm
hey Sebastian, can you please tell me how to install missing CheckpointLoader NF4? I tried with the regular loader but it doesnt work. Thank you! edit: guys, you can check Rusty dog tut on how to solve this, it worked for me : )
I had to go into my config file and change the security_level to = weak to install the checkpointloaderNF4. Currently running at security_level = normal-. Sry guys, I new to all this lol
Hello there! Thanks for your video, it's really nice that you share your experience, but sometimes, people like me (noooob) who follow your instructions don't understand what to do and how to do it. Where to get this or that node from and so on... Yes I am a nooob and I really want to understand all your manipulations. Thank you very much! P.S.

Why are there no overlapping tiles? That would solve the seams issue.
Q for ya. Why dont you use flux. the unet model version? Is this one better? I noticed you dont have other clips.
