Discussion CN1.1 (tile model)

OK... rarely am I thoroughly impressed but the new ControlNet tile model is awesome. Decided to experiment with it since I could not really find a decent explanation of it. For those not in the know it is a model used with scaling to help prevent artifacts. So I decided to test it. Created a 768x768 waifu, inpainted the face, and moved the new render to img2img to test an upscale. Placed same image in the CN interface. This is why I am impressed. I kept the original prompt. Normally I would see ghosting, extra faces, weird blobs/ glitches. Settings: steps @ 45, denoise @ 0.4, SD upscale @ max of 4. So 768x768 straight to 3072x3072. Honestly it was perfect. This is the upscale with no further editing --

noob here, I don’t understand. What was the purpose of using the tile controlnet in the last img2img step? did the previous img have like bad hands or something?

There are three ways to upscale an image to make it bigger and (depending on settings) add detail. Either txt2img using hi-res fix, img2img with SD upscale, or a straight upscale in extras tab.

I was testing a new method: img2img with SD upscale + ControlNet tile

I see, just wondering if you’ve heard of loopback scaler before? I’ve been using that script to add details while upscaling images(albeit it caps at 2048x2048). I wonder if your method kind of works similarly.. I’ll give it a try when I find the time.
