The lotus-eaters of Xuthal built a city in the desert and forgot how to maintain it. This LoRA builds cities that remember themselves.
City Sim is a style LoRA that transforms any scene into an isometric city builder / miniature world aesthetic. Think SimCity meets tilt-shift photography meets storybook illustration -- colorful rooftops viewed from above, tiny cars on winding streets, parks with miniature trees, the warm glow of a world that fits in your palm.
No trigger word needed -- the concept activates when you load the LoRA. Describe any scene and it becomes a miniature world.
Completely SFW. Part of the World Morph series.

City Sim — Isometric City Builder [F.1D/Illu]

City Sim transforms any scene into an isometric city builder miniature world. Colorful buildings, tiny cars and pedestrians, tilt-shift depth of field, and the satisfying grid-based geometry of a city simulation game. The Flux version delivers clean photorealistic miniatures with natural lighting and depth — buildings cast real shadows, windows catch light, and the tilt-shift blur feels like macro photography of a physical diorama.Settings: Strength 0.70–0.90, Guidance 3.0–4.0, Steps 20–30. No trigger word needed.
