multi sample pixel space sharpening

I think this is a good name for it. Not sure.

Takes an image from text prompt and

• samples it
• uses a model to upscale
• resamples it
• repeats
• at the end, uses uses a 4x upscale model to increase the size again
• saves it at a total of x8 size

Basically a series of hi-res fixes then an model upscale

Moving noodles switches between model vae and vae loader.

Example

Variations

• with latent upscaling.

• Using the standard image upscale nodes

• a fast one with smaller images sizes to "check it out" sort of thing.

• adjusted image sizes, added img2img nodes, cleaned up some lines and nodes
  

• save filename prefix nodes

• using tiled ksamplers and tiled vae

  • requires blenderneko's tiled ksampler
  • also includes the newest version of custom folder/prefix substitution
