explaining the offset lora example is great information as well @ 6:54 I had no idea what that thing was about until your video thank you

[wolfhound]

What’s taken me days of experimentation to figure out, you explained in this video - plus more. Greatly appreciated.

[dezpe]

Thanks man. Very nice tutorial. Comprehensive and to the point. I will be coming back for more tutorials on Fooocus.

[raulcamarena]

Great explanation on what Loras and checkpoints are, and how to use them! i was having trouble understanding these concepts but now im able to generate better images.

[mauricioc.almeida]

Thank you so much! I'm really impressed with FOOOCUS. I was a big fan of Mid, and I can see your tutorials, have had a major impact on my skills with stable diffusion.

3:40 is good info about why people still tend to use 1.5 beyond hardware requirement and just getting different results

[ximorro]

I think the refiner in Fooocus doesn't add more time to generate the image because it's not creating the full image and then refining as a second full pass. What it does is to exchange the model in the middle of the generation (in this case at 80% as put in the slider) so that at the end the number of steps is the same regardless you use the refiner or not.
That said, it's probably better to use a model that doesn't need a refiner and you save 6GB of disk space.
That option is useful even when not using a refiner though: you can use it to flip to a different model mid-generation, creating the structure with one and then polishing the details with another... and you can use 1.5 models there! It's a way of using 1.5 models if you switch sooner (as explained i the text with the option) so that the main generation will be with the second 1.5 model.

thank you for your patience explaining everything!
I find it difficult to upscale a base image without changing details. Is there a way to preserve 100% original details ?

[JayPatel-hmvb]

I am using Colab for image generation and i want to use Realistic Vision v6.B1 model as refiner can you tell me how to download that model directly in colab?

[komsomolac]

I love your videos, man. They are very helpful to a newbie in the world of AI digital image creation, like myself. I think I understood everything you talk about in this video, but I don't understand the "Random" command and those "seeds." Would you care to elaborate?

[bindys]

Thanks for the 4-parts tutorial of using Fooocus! But what I haven't found yet is how to control the steps? Mine always set to 60 steps, is it possible to reduce that?

[Sean-voxo]

Awesome video!
Just to clarify, is it not possible to use SD 1.5 with Fooocus?
If not I would really appreciate the tutorial to customize Fooocus to make it possible to use SD 1.5 models.

[Something]

Please make a video to how to switch Fooocus to Defooocus (Fooocus Latest version)

[rorroteck]

Thank you very much, your videos are very good, I have subscribed to your channel, where do you run fooocus? What hardware do you have? How long does it take to generate an image? I ask you because I have an Nvidia M4000 GPU but it is very very slow, 24 minutes to generate a high quality 1408x704 image. Is that time normal?

[moonduckmaximus]

where is the updated fooocus version. im tryin to find a video that explains the control net tab that should be next to the other tabs in your video

[AvncheTMC]

So the LoRas for SD 1.5 won't work in Fooocus, even if I use SD 1.5 models as a refiner, correct? Should I only search for and use SDXL 1.0 based LoRas? Should I even bother with refiners? Sometimes I get weird results for eyes and sometimes hands and I haven't yet figured out, if it's my prompting or refiner and LoRa's fault...

[waltermiller]

i downloaded the same models and placed them into the checkpoints folder but still they do not appear on the seleciton list.
