I had low expectations that this would actually work, but am pleasantly surprised. Delfino Plaza is a location in Super Mario Sunshine, and the LoRA I used was entirely trainied on screenshots from a 20 year old GameCube game. The fact that Stable Diffusion was able to translate that into convincing real-world background locations is blowing my mind.
