The prompt
We are going to build a large, explorable 3D world with Three.js and Vite. At the center, create a massive castle on a hill that the player can walk toward, enter, and explore.
Really focus on making the world feel alive and cinematic.
Prioritize detailed lighting, volumetric clouds, dense grass, wind simulation, particle effects, god rays, atmospheric fog, and polished camera effects.
The castle should feel AAA-quality, with imposing architecture, a functional drawbridge, outer walls, towers, and a large interior courtyard.
Make the entire experience feel cohesive, immersive, and visually incredible.
How to use this prompt
Choose one thing to change
Swap the subject, art style or setting. Keep the camera and interaction clear. Build a small version first, then refine one detail at a time.
Give the scene its own assets
For a custom character or prop, create a 3D model from a short object description or reference image, then bring it into your project.
