GPT-6 AstraReference brief
Isometric fantasy graphics demo
An interactive browser-based fantasy 3D scene with an isometric camera, voxel-inspired art direction, wet reflective floors, and a movable character. The linked Dream Loop repository presents this as its example prompt and states that it was tested with GPT-6 Astra in Codex. It requests no gameplay loop.

The prompt
Build me a graphics demo: isometric camera, voxel-ish art style with realistic shading and reflective wet floors, a character in an interesting scene. Fantasy setting (think Elden Ring, Diablo). Three.js in browser, >60fps. Don't download assets. Time limit of 1 hour. Controls: click to move the character, camera lazy-follows; drag to rotate camera; scroll to zoom in/out. No gameplay for now. World should feel alive: motion, animations, subtle environmental behaviors. Area around player should look expansive, but only allow movement in a limited space. No need to confirm the art with me or ask questions, just go!
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.
