"prompt": "Subject: [INSERT CITY/LOCATION NAME].
Create a hyper-realistic isometric architectural maquette of the Subject, strictly isolated on a seamless pure white studio background.
[Surface Level]: Analyze the Subject to recreate its signature architectural style, vegetation, and street atmosphere.
- **Architecture**: Representative buildings with authentic materials (e.g., brick, glass, wood) and local design details.
- **Street Scene**: Localized vehicles, street furniture, and scattered life details appropriate to the location.
[Underground Level]: A deep vertical cross-section revealing underground elements strictly based on the Subject's real-world infrastructure:
- IF it is a modern metropolis: Show complex subway tunnels, maintenance pipes, and concrete foundations.
- IF it is a historical or rural site: Show rich soil stratification, ancient ruins, sewers, or deep root systems.
[Crucial Lighting & Material Details]:
1. **Lighting Physics**: The strong sunlight from above must cast distinct, hard shadows from the street level down onto the underground cutaway sections. The underground should be slightly darker, lit by its own dim interior lights (if infrastructure exists) or fading into shadow, creating a contrast with the bright surface.
2. **Soil Texture**: The earth layers must look realistic and gritty—soil mixed with rocks, gravel, and roots. No smooth textures.
3. **Photography**: Macro lens photography. Shallow depth of field (tilt-shift focus on the main building) is mandatory. The background MUST be empty white void.
[Technical]: 8k resolution, Unreal Engine 5 render, highly detailed physical model aesthetic.",
