GPT-6 AstraReference brief
Reachable procedural space exploration game
An OpenAI developer’s initial brief for Void Explorer, a browser-based 3D space exploration game. It requests a continuous journey from space through a planet’s atmosphere to the ground, with real-scale distances, Earth-sized planets, procedural terrain, and chunked rendering.

Creator notes
Build a playable 3D space exploration experience where every visible destination is reachable. Preserve real-scale distances while making travel practical through scale and speed. Let the player fly continuously from space into a planet’s atmosphere and down to the ground. Support planets as large as Earth with procedural terrain and a chunked renderer.

The prompt
Everything I can see should be reachable. Keep the distances real, then make travel work through scale and speed. I want to fly from space into a planet’s atmosphere and down to the ground. Planets can be as large as Earth, so we’ll need procedural terrain and a chunked renderer.
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.
