Fable 5.1 Autonomously Adds Day/Night Cycles and Reactive Crowds to a Unity Tennis Game
chongdashu · x · 2026-09-02
Developer chongdashu shows Fable 5.1 iterating on his Unity robot tennis game.
- In earlier work, he built the prototype, Blender rig, and animations using Blender MCP, Unity CLI, and AI tools; the robot character came from Meshy via a single image, with other assets generated directly by the LLM.
- Fable 5.1 then autonomously added day/night cycles, reactive crowds, lightning, and visual polish, a clear leap in its game dev skills.
- Video demo shows working forehand, backhand, smash, and serve controls and animations.
