I was trying to upscale this image in img2img to 1024x1024 and was really struggling. I couldn’t preserve the patterns in her gown and for some reason the gown wouldn’t stay in her right hand, it’d fall against her leg, and was longer for some reason. Trying to force-correct these things often ended up with distortions. Any ideas?

Example of fail

Here’s the generation for the 512x512 above:

    If you don’t use hires fix during generation, you can also upscale afterwards by using the hires fix upscalers in the extras tab in the web-ui.

      Going with what pinecone mentioned here, this is what i do most of the time. like 9.99/10 of the time.

      Basically, hires fix > base resolution of 512x768 (by upscaling with 2, which will generate an end image of 1024x1536).

      then u can move that gorgeous (but tiny resolution) image to your extras, to then get 5120 x 2880 or whatever resolution

      PS: a cool method to use for horizontal images (like wallpapers) instead of vertical like phone wallpapers, is to switch the values. so instead of 512x768 u can do 768x512
