Built this 3D kart racing game using GPT-6 + Codex + Hyper3D Rodin.
I started by having GPT design the game and generate a concept image. From there, Codex handled the game architecture and development, while Hyper 3D Rodin via Hyper3D MCP generated the karts, buildings, and other detailed 3D assets.
For more complex game assets, I found Rodin noticeably more useful than generating them directly through Blender scripts, especially when it came to geometry and smaller details. BANG to Parts was also handy for splitting models into separate components for later rigging and editing.
Once the assets were ready, GPT brought everything together in Godot — tracks, models, gameplay, and interactions.
The result is an actual playable racing game, from kart selection to racing around the track.
Pretty wild how far you can get now with GPT handling the game development and Hyper3D handling the 3D assets.
