Meta Introduces WorldGen to Generate Interactive 3D Worlds from Text

• WorldGen produces large, navigable 3D environments from a single text prompt using an end-to-end generation system.
• The research tool aims to simplify worldbuilding by eliminating the need for manual 3D design or code.

Meta has introduced WorldGen, a tool that turns a simple text prompt into a fully interactive 3D world. As part of a recent research update, Meta showed examples of how users can enter phrases like “cartoon medieval village” or “sci-fi base station on Mars” and get a complete, explorable scene in minutes with no modeling or coding required.

WorldGen begins by generating an image of the scene, then reconstructs it into a full 3D environment. From there, it adds layout structure, navigation paths, and objects, followed by mesh and texture cleanup. It can create full spaces up to 50 x 50 meters that stay consistent as users move through them, rather than focus only on one viewpoint.

WorldGen is still a research project and not yet available to developers, but Meta says that the 3D worlds it produces can already be used in Unity and Unreal without extra processing. The company plans to support larger scenes and speed up generation in future versions to make worldbuilding more efficient and accessible.

🌀 Tom’s Take:

Generative 3D systems like WorldGen point to a massive unlock for immersive content and simulation, which are key ingredients for training, testing, and scaling physical AI.
