1 month ago @antonioo-c In the future, it's helpful to show what kind of artifacts you are experiencing by attaching an image (maybe a small cropped piece of the image with the artifacts visible). Sometimes when I was using the workflow I got the kind of weird tile/line artifacts that FLUX makes sometimes, so I'll assume that's what you are talking about. There's a few options for trying to improve things:
- Make sure FLUX can understand your prompt even without regional control. I've heard that some of the artifacts come from when you prompt FLUX for something "out of distribution", or a prompt it doesn't understand.
- Make sure you have enough steps. Some images genuinely take 50 steps, especially when FLUX is confused, although in these cases I would recommend changing your prompt as recommended in the previous step.
- Create a regional prompt that will be shared with the whole area (so a third or fourth region but with a mask for the whole image instead of part of it). This will help FLUX understand how the overall composition should look and will also weaken the regional effect slightly.
- Consider using a LORA to combat some of FLUX's built-in blurriness. I know a lot of people work on this on Civitai, but I don't know the current best LORAs for this. As always, test these things without regional conditioning first.
- If you like your image, but it's just a matter of a few issues, run it through a second pass with low denoising and a single global prompt, as you would in a regular img2img workflow. You can even do a second pass with an SDXL model or SD1.5 model if you want to fix skin texture or get a style from a SD1.5 model.
Let me know if any of this works for you so others can know the best path forward!
Hello, thanks for sharing the wonderful results with FLUX. I was trying to implement myself but the background always had some blur or artifacts. I wonder if its possible to share how you deal with it. Thank you!
