Text to 3D World: describe a place, explore it in 3D
Type a prompt and get an explorable 3D world built with World Labs Marble. Walk through it in your browser, then export it for Unity, Unreal or Blender.
How text to 3D world works
1. Describe a place
Write the space, not a single object: where you are standing, what surrounds you, the light, the materials and the style.
2. Pick a Marble model
Marble Draft is estimated at about one minute for 20 credits, good for testing an idea. Marble 1.1 takes about five minutes for 100 credits at the current catalog price.
3. Explore and export
Walk through the result in your browser. Export splats (SPZ / PLY), a 360° panorama or a GLB for Unity, Unreal or Blender.
Prompt tips for better worlds
Name the viewpoint
“Standing in the nave of a ruined cathedral” gives the model a place to put you. A bare noun like “cathedral” leaves it guessing.
Describe light and time
Golden hour, overcast, neon at night: lighting changes the mood of the whole scene more than any single object.
Start with a Draft
Test the composition with a Marble Draft first, then spend credits on Marble 1.1 once the layout looks right.
Prompt in, world out
Spatial inspiration from Marble creators. These are community worlds, not outputs from our image or video models.

FAQ
What is a text to 3D world generator?
It turns a written description into a spatial scene you can move around in, instead of a flat image or a single 3D object. Worlds here are generated with World Labs Marble.
How is this different from a text to 3D model tool?
Text to 3D model tools return one object, such as a chair or a character, as a mesh. A 3D world is a whole environment around the viewer, useful for game levels, film previs and VR scenes.
Is it free to try?
Eligible verified accounts receive 30 free credits, enough for a 20-credit Marble Draft. Check the studio for current costs before submitting.
How long does a world take?
Marble Draft is estimated at about one minute and Marble 1.1 at about five minutes; queue time and complexity vary. Failed tasks refund the deducted credits.
Can I start from a photo instead?
Yes. Use Image to 3D World to build a scene from a photograph or concept image, or Panorama to 3D for a 360° image.
