3D Worlds
Generate persistent, navigable 3D environments from text or images.
3D Worlds creates full 3D environments you can walk through, capture shots from any angle, and revisit any time. Powered by World Labs Marble. Generate from a text description or a reference image. Draft worlds render in 30 seconds. Full quality worlds in five minutes. Every world is saved to your library and can be re-entered weeks later with total scene consistency.
Example outputs
“A sun-drenched Mediterranean courtyard with terracotta tiles, olive trees, and a stone fountain in the centre, warm afternoon light”
“A futuristic space station interior with curved white corridors, holographic displays, and viewport windows showing a planet below”
“A cosy mountain cabin interior with log walls, a crackling fireplace, bookshelves, and snow visible through large windows”
“An ancient temple ruin overgrown with jungle vines, shafts of golden light piercing through the canopy, stone carvings on walls”
“A brutalist concrete gallery space with double-height ceilings, polished concrete floors, and large abstract sculptures on plinths”
“A neon-lit cyberpunk alleyway at night, wet pavement reflections, holographic signs, steam rising from vents, narrow walkway between buildings”
How it works
Describe or upload
Type a text description of the 3D model you need, or upload reference images from 1-4 angles.
Choose your model
Pick a 3D generation model and configure settings. See the credit cost before you generate.
Generate and export
Your 3D model is ready in seconds. Download in FBX, GLB, OBJ, or other formats for your pipeline.

3D Worlds generates full Gaussian splat environments from a text prompt or reference image. The result is a persistent, navigable 3D space you can move through freely using keyboard and mouse controls. Position your camera at any angle, capture the viewpoint as a production-ready 2D image, and use that capture as input for video generation, compositing, or client presentations.
Every world is saved permanently in your library. Return to the same environment weeks later and the scene is exactly as you left it. This gives you total consistency across a project: generate one environment, capture dozens of angles, and every shot shares the same lighting, materials, and spatial relationships. No more regenerating similar-but-different backgrounds for each frame.
Two quality tiers let you iterate fast and finish sharp. Draft mode (Marble Mini) renders a navigable world in around 30 seconds. Full quality mode (Marble Plus) produces a high-fidelity environment in around five minutes. Start with drafts to find the right scene, then generate the final version at full quality.
Persistent, revisitable environments
Every world is stored in your library with a thumbnail preview. Click to re-enter any world at any time. Scene consistency is guaranteed across sessions, making 3D Worlds ideal for projects that require multiple shots from the same environment over days or weeks.
Frame capture and compositing
Position your camera anywhere in the world and capture the viewpoint as a high-resolution PNG. Use the captured frame as a starting point for image compositing, video generation, or as a reference for further AI generation. Camera positions are saved so you can return to the exact same angle.
Text or image input
Describe the environment you need in natural language, or upload a reference image. The AI builds a full 3D space that matches your brief. Interiors, exteriors, landscapes, fantasy environments, architectural spaces. If you can describe it, you can walk through it.
