What's the best way to upscale drawings/illustrations/paintings? (lemmy.world)

I'm pretty new at this but loving it. I've been messing around with illustrations, ink art, sketches and watercolours, which has stunning results. The default upscalers create a smooth texture, sort of 3d and a bit photo realistic, and it just looks weird.

And where do I find and install upscalers?

Better than ultimate SD upscaler: https://github.com/pkuliyi2015/multidiffusion-upscaler-for-automatic1111

Combined with controllnet tile upscale it provides amazing results.

So I did install this but couldn't find "Tiled VAE" or "Tiled Diffusion" anywhere in the UI.

Is controlnet something I have install separately?

Yes you have to install ControlNet separately.

But you should already see the Tiled VAE and Tiled Diffiusion plugin.

Watch this video to see how it should look. Also a guide for this method: https://youtu.be/KkxNEiiBOyQ

Oh I do have them. Was looking on Extras with the upscaling settings.

Watch the video for settings. It is quite complex. If you want to add detail or change the image more try ControlNet+Ultimate SD Upscaler script. It is also easier with the settings: https://stable-diffusion-art.com/controlnet-upscale/#Method_3_ControlNet_tile_upscale
