Creator: ThalisAI

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.

Features

Isometric perspective: Top-down city builder view, everything rendered from a consistent elevated angle
Tilt-shift depth of field: Miniature effect that makes scenes look like scale models
Colorful rooftops: Vibrant tiles, varied materials, warm urban density
Tiny details: Micro-scale cars, pedestrians, trees, market stalls, swimming pools
Storybook warmth: Soft lighting, inviting color palettes, the visual language of beloved city games
Genre versatility: Suburban, fantasy, cyberpunk, medieval, desert, tropical -- all become miniature worlds

About Illustrious version

The Illustrious version renders the city builder aesthetic with more saturated colors, sharper linework, and a stylized quality that leans closer to the hand-painted feel of actual game art. Buildings pop with cartoon vibrancy while maintaining the isometric perspective and miniature scale.

Settings: Strength 0.60–0.85, CFG 5.0–7.0, Steps 20–30. No trigger word needed.

Recommended Settings

Trigger: None required — the style applies automatically
Strength: 0.7–1.0

No trigger word -- the city sim aesthetic applies through strength alone
Start at 0.80 and adjust for both bases
City and architectural prompts work best: "aerial view", "isometric", "city", "rooftops", "miniature" reinforce the effect
Works on any geographic/cultural context: medieval European, Japanese, Arabic, Nordic, tropical, futuristic
Combine with environment detail: "swimming pools", "market stalls", "tiny cars", "colorful tiled rooftops"
