Marble

What it does

Marble takes text prompts, single images, multiple images, video, 360 panoramas, or coarse 3D layouts built from boxes, planes, or imported assets, and generates persistent 3D worlds. You can edit parts of a generated world, expand a selected region, or combine several worlds into a larger space. Worlds can be exported as Gaussian splats, triangle meshes (including collider and high-quality meshes), 360 panoramas, or videos with camera control.

Artists and designers often generate a starting world from a prompt or image, then refine it with edits, expansion, or multi-image inputs when they need more control over layout or appearance. Chisel mode separates structure from style: you block out rough 3D geometry, then apply a text prompt to define the visual design. Marble Labs publishes case studies and tutorials showing Marble used in film, games, robotics simulation, and architecture.

Marble is aimed at artists, designers, engineers, and creators building 3D environments, with examples in virtual production and robotics. You access it through the web app at marble.worldlabs.ai, where plans are credit-based and the Free plan includes up to 4 world generations. Sign-in is required to subscribe, and credit costs vary by action.

What it can do

• Generate 3D worlds from text prompts or single images
• Generate worlds from multiple images or video with transitions between views
• Build coarse 3D layouts in Chisel mode and restyle them with text prompts
• Edit worlds with local or large-scale changes such as removing objects or changing style
• Expand selected regions and compose multiple worlds into larger spaces
• Export worlds as Gaussian splats, meshes, 360 panoramas, or rendered video

Works with

• THREE.js (via Spark renderer)
• NVIDIA Isaac Sim (case study workflow)
• Unreal Engine (case study workflow)

Example workflows

Generate a world from a concept image

Input: a single image or text prompt describing a scene. Steps: submit the prompt in Create, review the generated world, then use editing to adjust elements. Output: an editable 3D world that can be exported as a splat or mesh.

Lay out a room in Chisel and restyle it

Input: coarse 3D boxes or planes, optionally imported 3D assets, plus a text style prompt. Steps: block out the room structure, add the style prompt, generate, then vary the prompt to test alternate looks. Output: detailed worlds that share the same layout with different visual styles.

Before you choose

• Credit costs differ by action: image input is 80 credits, world generation at Marble 1.0 is 1,500 credits, and exporting a high-quality mesh is 3,500 credits.
• Commercial rights are included on the Pro and Max plans, and high-resolution textured mesh export is a Pro-tier feature.
• Access may be limited by a waitlist or Atlas access message, so new users may not get immediate access.
