Meta announces WorldGen 3D world generator

Meta has unveiled WorldGen, a new system designed to generate fully interactive and navigable 3D worlds from a single text prompt.

Meta, the brand behind Facebook and Instagram, has introduced WorldGen. Users can create 3D worlds all from a text prompt.

It can create geometrically consistent 3D environments such as medieval villages or sci-fi bases, with layouts that allow characters to move freely. The system uses procedural reasoning, diffusion-based 3D generation, and object-aware scene decomposition.

WorldGen outputs are compatible with common game engines including Unity and Unreal Engine, with no additional conversion required. Meta says larger world sizes and reduced generation time are planned for future versions.

The WorldGen pipeline includes several stages: planning, procedural blockout, navmesh extraction, reference image generation, image-to-3D reconstruction, scene texturing, AutoPartGen-based decomposition, and final refinement for both meshes and textures.

Although still in the research phase and not yet available to developers, Meta sees WorldGen as a major step toward democratizing 3D content creation, enabling people to build complex virtual worlds without writing code.
