Marble is a 3D world generation platform from World Labs that creates persistent 3D worlds from text, images, video or 3D structures, with editing, expansion and multi-format export.
Marble: the 3D World Generation Platform from World Labs
Introduction
Marble is a 3D world generation platform from World Labs. It builds high-fidelity, persistent 3D worlds from a simple text description, an image, a video or a 3D structure. It accepts several input types - text prompts, single or multiple images, panoramas, video and basic 3D layouts - and offers panorama editing, click-to-expand and world variants so users can refine the result. Generated worlds can be exported in several formats for web sharing, VR experiences or production assets.
The platform is aimed at artists, designers and anyone interested in creating 3D worlds. The official site is https://marble.worldlabs.ai/.
Key Features
Multimodal input：Accepts text descriptions, a single image, multiple images, video, panoramas and basic 3D layouts, so users can pick the most convenient way to generate a world.
AI-native editing：Lets users describe changes in natural language for local edits, object replacement, style changes or large structural adjustments.
World expansion and composition：Expands world boundaries with one click, fills in additional content and refines edge detail; a composition mode stitches several worlds into a larger environment.
Chisel：Builds a 3D frame from basic primitives such as cubes and planes, and the AI fills in details from a style description; one frame can produce many styles.
Full-format export：Exports to Gaussian Splats, triangle meshes and video for use in game engines, VR devices or other professional tools.
Dynamic effect enhancement：Automatically adds dynamic effects such as smoke, fire and flowing water when exporting video.
Real-time rendering and preview：Uses the Gaussian Splats format for real-time rendering and preview in the browser, making it quick to review and adjust.
How to Use
- Go to the official site https://marble.worldlabs.ai/, register an account and sign in.
- Choose how to create: text, image, video, panorama or 3D structure.
- Submit the input and let the platform generate an initial 3D environment.
- Refine the details with panorama editing, click-to-expand or world variants.
- For larger scenes, use the studio tools to combine worlds or record a dynamic video.
- Export for web sharing, VR, production assets or 3D printing.
- Browse community works for inspiration and share your results with others or in projects.
Pricing
- Free plan: 7,000 credits per month, up to 4 worlds, including text input, image input and 360-degree panorama input.
- Standard plan: 20 USD per month, 20,000 credits, up to 12 worlds, adding multi-image input, video input, advanced pipeline editing and Chisel 3D layout control.
- Pro plan: 1 USD for the first month as a limited offer, then 35 USD per month, 40,000 credits, up to 25 worlds, adding expansion to larger spaces, enhanced rendered video output and high-resolution textured mesh export.
- Premium plan: 95 USD per month, 120,000 credits, up to 75 worlds, including everything in Pro plus commercial use rights.
Use Cases
- Game development: generating backgrounds and scenes quickly and supplying designers with 3D environment resources.
- Film and video production: building scene previews and shot plans to shorten the path from idea to visual.
- Architectural design: generating interior and exterior environments to present design proposals faster.
- VR and AR experiences: creating immersive virtual environments for use directly on VR devices or in AR apps.
- Education and training: building virtual teaching scenes such as historical reconstructions or science experiment settings.
Limitations and Notes
- Each tier has different credit and world limits; once exceeded you need to upgrade or wait for credits to reset.
- The free plan does not include multi-image input, video input or Chisel mode.
- Output quality depends on input quality: blurry images or very brief descriptions reduce detail.
- For commercial use, check whether your plan includes commercial rights; currently only the Premium plan does.
- Large scene composition and high-quality exports consume more credits, so preview before exporting.
