Active·★ 13·MIT·Updated 2026-10-18

Hayba is an agentic engine that enables AI agents like Claude or GPT to directly author Unreal Engine 5 scenes by spawning actors, building PCG graphs, and validating physics. It provides a spatial-first approach with a PCG SQLite registry, a cognitive map, and a visual grounding sidecar, extending AI capabilities for complex 3D world creation.
