Agent builds a fishkeeping game in Unreal Engine with Thrixel assets as Build World adds UE support
RanaHanocka · x · 2026-09-21
Fable and Thrixel demoed a fully agent-driven pipeline: the agent picked a Japandi style, generated assets with Thrixel, populated an Unreal Engine level, and wrote the gameplay logic to produce a peaceful fishkeeping demo.
The underlying Build World tool now supports Unreal Engine—users just describe what they want to build. It's a notable step for coding agents moving beyond code into full 3D game development.
