Mesh export: downloading 3D assets
Export your Marble worlds as 3D meshes for use in game engines, 3D software, and other applications. Choose from multiple mesh formats and quality levels to suit your specific needs, from quick prototyping to high-quality production assets.Collider mesh export is included with the Standard plan. High-quality textured mesh (GLB) export requires the Pro plan.
Getting started with collider mesh export
You can export collider mesh along with a splat to provide simple physics for games. For example, see first person shooting game. To download collider mesh, navigate to the download menu from world viewer, or world in Worlds, and download from the Collider Mesh (GLB) link.Getting started with high-quality mesh export
- Trigger offline generation: Select High-quality mesh (GLB) from your world’s export options
- Wait for processing: High-quality mesh generation takes up to an hour to complete
- Continue working: You can close tabs and browser windows - the process continues in the background
- Download when ready: Return later to find a High-quality mesh (GLB) button replacing the generate option
- Access premium quality: Download detailed meshes, one around 600k triangles and texture maps, another around 1M triangles with vertex colors.
FAQ
How long does offline mesh generation take?
High-quality mesh generation could take up to 1 hour, depending on world complexity and system load. You can close your browser and the process will continue in the background.Can I use collider meshes for visual rendering?
No. Collider meshes are optimized for physics interactions and have simplified geometry. For visual rendering, use splats or the high-quality offline-generated meshes instead.Why does my high-quality mesh have artifacts or bad geometry?
Meshes are derived from the world, while the Gaussian splat is Marble’s highest-fidelity representation, so some reconstruction artifacts are expected. Uneven geometry, holes, and blobby or “floater” surfaces show up most in regions that are hard to reconstruct: thin or complex structures, transparent or reflective surfaces, sky and background, and areas the input views didn’t cover well. To get a better result:- For the cleanest visual quality, use a splat export instead of a mesh.
- Compare both high-quality mesh files. The ~600k-triangle textured GLB and the ~1M-triangle vertex-colored GLB can differ in where artifacts appear, so one may suit your scene better.
