Hey RedViperPT, Nice mod :)

I would like to create a HD-Version of my Mod Combi Factories https://mods.factorio.com/mod/combifactories to make it visually compatible with your mod.

Would you mind to tell, which machine-learning-software and settings you used to scale up the vanilla sprites so I could do the exact same with my sprites?

That would be nice :)

Hey jq_rospa,

I don't know which tool RedViperPT used, but I have had good experiences with Upscayl. (https://upscayl.org/) It is free and Opensorce.
There are not many settings and you can quickly try out the different upscale models to find the right one for the picture type.
Then you can edit all the images in batch processing.

I hope I was able to help you with this.
