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.
