smea sampler experiments for a1111 webui
These sampler has nothing to do with NAI's sampler or Euler sampler, I'm just suck at naming them.
(smea here stands for "Shovel More Extra Artifacts")
originally created by Koishi-Star and ananosleep
TCD sampler from dfl

RECOMMEND: Use: Smea mbs2 (#) / Smea mds2 (#) / h max (#) / Max(2b/3c/4b), they add details (or artifacts) more reliably

Also check Dynamic Thresholding, you can add more details

Euler Dy: og Euler Dy with DPM2 tweak, toggle on/off every step
Euler Smea: og Euler Smea Dy with DPM2 tweak, use smea sampling only, toggle on/off every step
Euler Smea Dy: og Euler Smea Dy with DPM2 tweak, loopping scale up > folded to 1/2 size > normal >... every step
Euler Smea dyn a: Euler Smea with DPM2 tweak (less sigma), toggle on/off (scale up) every step every step
Euler Smea dyn b: Euler Smea with DPM2 tweak (less sigma), loopping scale down > up > normal >... every step
Euler Smea dyn c: Euler Smea with DPM2 tweak (less sigma), toggle on/off (scale down) every step every step

Explanation:

The reason of many experiments is due to og sampler tends to blurred the background or overfry the image,
so I checked DPM2 sampler and experiment if it's worth to tweak it
What Smea sampling do is scaling latent image > denoise > scale it back to original size
What dy sampling do is shrinking latent image to 1/2 size > denoise > extend it to original size
since what they did is bascially just scaling latent image, I use smea sampling only
What all these samplers do is bascailly trying to combine different scaled latent image to denoise image to generate better details (artifacts)
