[Question] Different aspect ratios and resolutions

Open Mikerhinos opened this issue 2 years ago • 3 comments

Very interesting experimentation. I was able to get crispy 1024x1024 images like this one ComfyUI_00403_ I didn't tried to SD upscale it yet though because I tried to modify some settings to get different resolutions/ratios but failed everytime. Is there a way to do it or (for now) we're stuck to 1024x1024 images ?

I've just updated the readme but indeed there is a limitation. My best guess is that the resolutions have to be multiples of 64.

64 because the perlin noise scale is 8 and the latent space is 8 times smalled than the final image.

just an edit to say that your image is really cool!

It seems related to the scale. I can go 1280x1280 if I down the scale from 8 to 5. ComfyUI_00577_ I don't know what I'm doing, just fiddling with all the settings until it looks like an image lol. Though when trying some realistic face it's not the same story.

I don't know what I'm doing,

Me neither!

I've got so far until I was able to get viable noise. I updated the node so to add an option to center each perlin layer to get a mean value at 0 which definitely seems to make the generator more flexible but really I got surprised that you got an image with a lower scale because so far I was not able to get anything viable below 8
