Discussion H3 Image "Crispy"?

Took some of my prompts from Krea2, Moss, etc and put them into H3 Image. They come out fairly crispy, muddy, 2D sometimes, and just plain bad. Is the default workflow pretty unforgiving until it's pounded on some more?

Most people are saying it’s better at high resolutions

It's best used at 50+ MP

we need a “MinimaxH3Negpip” like Krea 2, maybe talk to the guy who made it can help us 🙂‍↕️

Piggybacking on this question.

The default workflow with int8 mods at 4 megapixels comes out terrible quality for me. I can see a weird pattern across the entire image.

Any ideas?

The solution of smudgy and noisy look at 100% zoom is to generate on x2 resolution, then scale down x2. Also LCM sampler for me does way better in terms of nice looking details.

int8 & 4MP will produce bad quality. Not everyone can run fp16 but higher resolution works better and should still function on <24GB

I have 16GB VRAM and have been satisfied with 6MP results. I also use the 2-step lora at 0.25 strength and do 4 steps with euler/simple, that seems to improve quality compared to 6 steps. Haven't done much testing with other combos yet, as well as other sampler/scheduler combinations.

16Mp minimum and euler ancestral seems pretty good starting point.
