dude GPT-6 Astra is some kind of turbo-AGI machine god for 3D games. It one-shot this in 45 minutes for hardly a couple % of my quota.
I figured out how to get great graphics out of it. The trick is image gen. I'll share the process below.

All I did was:
1. Connect Codex to Blender MCP
2. Paste in the concept for the game
3. Tell Astra to use the Codex image gen skill to generate concept images of the target art style, then iterate until in-game screenshots look as close as possible to those, at 60fps
Set to high reasoning.
Astra is stupid good at 3D modeling and vision. It noticed every little detail and didn't stop until the scene looked almost as good as the concept art. Modeled every asset in Blender. Used image gen to generate textures for the meshes. Everything here is made by Astra, nothing external.
The prompt is nothing special. It describes the game mechanics and asks for a "sad but beautiful dystopian theme with a voxel-ish art style, and lighting that feels real and physical."
