I first generated some 512*144 images via txt2img (target resolution ratio, with larger side reduced to 512 so that SD stay coherent with its generation. The "Aspect Ratio Helper" Plugin help a lot with that : https://github.com/thomasasfk/sd-webui-aspect-ratio-helper.git). High Res Fix "upscale" a first time to 1920x536, which is (approximately) my target resolution divided 2. I choose this resolution because it is a good compromise between what my computer can do and how much I still need to upscale later. In the High Res Fix setup, I only put "1920" as target width. The height is then automatically calculated based on the initial ratio. I then used, in img2img, the "Ultimate SD Upscale" Plugin (https://github.com/Coyote-A/ultimate-upscale-for-automatic1111.git) with ControlNet v1.1.179 (https://github.com/Mikubill/sd-webui-controlnet.git) to upscale them to my target resolution and add some details. Here are the setting I changed from the default ones : Input : my image Prompt & Negative prompt : same as txt2img Sampler: DPM++ 2M Karras Steps: 150 (max) Denoising strength: 0.7 (I wanted a high denoising strength to generate some details) Seed : -1 (I like to live dangerously) ControlNet Settings : Input : same image Enable : true (duh) Preprocessor : tile_resample Model : control_v11f1e_sd15_tile [a371b31b] (https://huggingface.co/lllyasviel/ControlNet-v1-1/tree/main) Control Mode : "ControlNet is more important" (Important for good results !!!)

No editing has been done, I just mirror-flipped some of them based on my personal preferences. There are a lot of incoherence, imperfections, etc. that can be fixed with some Inpaint/Photoshop, but I have neither the time nor the skills for that, so they will do as is for now.
Also, for some reason, I can't get the batch img2img to work with this process, so I had to manually upscale them one by one :'(
Prompt
"Mid-day in the ultimate (City:1.3), Dreamlike", scenery, gorgeous location design, a Medieval walled city plaza, (Sunny weather mood:1.1), (Summer color palette:1.2)
Some wallpapers I made ("quick" workflow, no editing/post-process)
To generate them, I started from a post I found while browsing this sub-reddit for inspiration : https://www.reddit.com/r/StableDiffusion/comments/11tuzov/for_anyone_who_isnt_already_aware_of_it_tiled_vae/
From this post, I picked the model (https://civitai.com/models/14734/store-bought-gyoza-mix), the VAE (https://huggingface.co/andite/pastel-mix/blob/main/pastel-waifu-diffusion.vae.pt), the "badhandv4" Textual Inversion (https://civitai.com/models/16993/badhandv4-animeillustdiffusion) and the prompt, which I tweaked to suit my need :
