At the end of the day, my hardware is not appropriate for SD, it works only through hacks like tiling in A1111. And while that’s fine for my hobby experimenting, I would like other people, or even myself once I finally upgrade my desktop, to be able to recreate my images in better quality, as closely as possible (or even try and create variations).

I already make sure to keep the “PNG info” metadata which lists most parameters, so I assume the main variable left is the RNG source. Are any of the options hardware-independent? If not, are there any extensions which can create a hardware-independed random number source?
