World Labs Makes Marble Public for Multimodal 3D World Generation

• Marble is a multimodal generative model that creates full 3D worlds from text, images, video, or 3D layouts.
• Now publicly available, it includes built-in editing tools and export options for creative and technical workflows..

World Labs has released Marble, its generative world model, for anyone to use. After a closed beta, the platform is now fully open to the public. Marble creates 3D worlds from a variety of inputs and supports editing and export for creative or technical projects.

Marble is a multimodal world model that builds 3D scenes from text, images, video, or 3D layouts. Users can mix these inputs to shape both the layout and look of a world. It takes just a few prompts to create detailed environments ready for creative exploration.

Marble includes built-in tools for editing generated worlds, from subtle adjustments to major scene changes. Users can remove objects, swap elements, or restyle entire areas. For more control, Chisel lets users block out a scene using simple shapes or imported 3D objects. They can then apply a text prompt to define how the final world should look, combining structure and style in a single step.

Once a world is complete, it can be exported as Gaussian splats, triangle meshes, or rendered video. These formats integrate with standard pipelines across creative and technical fields. For inspiration and guidance, World Labs has also debvuted Marble Labs, a creative hub where they showcases projects, tutorials, and workflows from creators using Marble across areas like design, simulation, and storytelling.

🌀 Tom’s Take:

Opening Marble to everyone is a turning point for worldbuilding. Creators can move from prompt to editable 3D scene using multimodal input, all in one place.
