You're probably better of using Real-ESRGAN: https://github.com/xinntao/Real-ESRGAN. It's pretty solid and fast, even has portable executables you can just use as is. The upscaler that comes with stable diffusion might work for you, but I suspect it'll probably do a better job at upscaling stable diffusion output rather than a natural images (might be wrong though).

Show HN: A couple of links about Stable Diffusion AI Generation

I've been studying Stable diffusion for some days and this Github page I linked in the title shows the incredible power that Stable Diffusion has Right now, and it is growing everyday. I think people on HN ought to know and discuss about it, and share their ideas and discoveries. It can do text-to-image out of nothing with a customer-grade GPU, and image-to-image for incredible variations that you can guide with the criteria you choose. https://imgur.com/a/Jt76AHA Just check that picture out, I made variations from the base picture top-left, either to black-ened, or to white-ened, or to the combination of both... The power is infinite. It is called "Prompts matrix". You can run it from your own computer preferably with 8GB VRAM+ GPU, or cloud-based virtual machine (I managed to run it on Microsoft Azure but not for cheap). To install Stab

le Diffusion and experiment for yourself, simply follow this page guidance: https://rentry.org/voldy#-guide- If you just want to try out simply you can check out "beta.dreamstudio.ai" but it's not free beyond the first 200 images. It is free on Huggingface but it's struggling with the demand so I Won't link it. It generates 512x512 imges, but you can ENHANCE the fuck out of it with this link: https://github.com/xinntao/Real-ESRGAN Check out the link "Portable Windows". You can commandline it and batch a whole folder with a .bat script, on Windows (and Unix of course). It's free, no strings attached (as far as I know). If you generate texture or paintings you can generate a normal map and a displacement map, with CrazyBump.com. You can BATCH it a whole folder to their respective normals. There is a free trial which does the job, but buy it if you can, because it's awesome. Here is a cool link about SD: https://lexica.art/ ("the SD search engine") Here's to showcase the most important PROMPTs the engine can handle: http://stable-diffusion-guide.s3-website-us-west-2.amazonaws... At this link, you can buy and sell PROMPTS: https://promptbase.com/ (it's a great place to have great ideas) Finally here's a database of prompts and their generated picture, to get ideas: https://laion-aesthetic.datasette.io/laion-aesthetic-6pls/im... That's it for what I learned as of know. I hope people will talk about that and so we can get more nerds into the Stable Diffusion and make it even more open and awesome. Thank you for reading

I'm currently trying to put 1000x wallpaper seamless textures into UE5 Marketplace. I'm saddened to see this news.^^. Well, fuck money anyway right? Here's a tip, you can produce all you need if you follow this guide: https://rentry.org/voldy#-guide- Just check what this stuff can do: https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki... This is the best page on the internet right now. The hottest stuff. Better than Bitcoin. You can get guidance and copy business ideas here: https://lexica.art/ https://laion-aesthetic.datasette.io/laion-aesthetic-6pls/im... http://stable-diffusion-guide.s3-website-us-west-2.amazonaws... For textures: Once you have generated the color map (diffuse) from StableDiffusion, you can use CrazyBump to BATCH create the normal map and displacement map. I'm currently at my 200th file iteration. http://www.

crazybump.com/ CrazyBump, all the cool kids are using it. Now this is where I'm at. Call me crazy. I'm forgetting stuff surely, but it's the best I can do. Go and change the world. PS: You can Batch Upscale the 512 to beautiful 2k+ with this link: https://github.com/xinntao/Real-ESRGAN
