Meta Reality Labs announced WorldGen on November 20, 2025 — a breakthrough research system that transforms a single text prompt into large-scale, navigable 3D environments spanning up to 50×50 meters. Combining procedural planning, diffusion-based reconstruction, and object-aware decomposition, WorldGen produces geometrically consistent, fully textured scenes with built-in navmeshes for real-time exploration in Unity or Unreal Engine. While generation takes minutes and real-time rendering achieves sub-200ms latency in engines, this marks a massive leap toward AI-powered world-building for gaming, VR, and simulation.

Tencent launched the international version of its Hunyuan 3D Creation Engine on November 25, 2025 — a browser-based powerhouse at 3d.hunyuanglobal.com that generates high-fidelity 3D models from text, images, or sketches in under 5 minutes. Supporting OBJ/GLB exports, low-poly topology, and seamless integrations with Unity/Unreal/Blender, it offers 20 free daily generations for individuals and API access via Tencent Cloud for enterprises. Already powering 150+ Chinese firms like Unity China and Bambu Lab, this debut marks Hunyuan's overseas breakout, slashing 3D workflows by 90% and challenging Luma AI's throne in gaming, e-comm, and VFX.
