How to export your world to Unity
Bring your own generated scene into Unity. First decide whether you need a visual Gaussian splat, editable mesh geometry or a flat panorama: these are different assets and use different import paths.
1. Choose your export
| Asset | Use |
|---|---|
| SPZ / PLY | Gaussian appearance; requires a compatible splat renderer |
| Collider GLB | Collision geometry; not a textured visual replacement |
| High-quality GLB | Mesh workflow; choose textured or vertex-color export |
| 360° panorama | Flat equirectangular reference |
2. Download from your world
Open your completed world in Library. Use Download to select an existing asset or request an available export. Check the credit quote before requesting a high-quality mesh. Wait for the export task to finish and then download it. Keep the original files and the world metadata together. Community examples are credited references; use their original source page for creator-provided downloads.
3. Import the mesh into Unity
Install a compatible Unity glTFast package through Package Manager. Put the exported GLB in your project Assets folder, wait for import, then drag the imported asset into the scene. Use the package documentation for the render pipeline and Unity version you are using. This route imports mesh geometry, not a Gaussian splat.
4. Check scale and ground alignment
For raw Marble splats, multiply centers and linear sizes by metric_scale_factor, then subtract ground_plane_offset from the centers’ Y coordinate. Use the returned values, not fixed example numbers. Apply the target renderer’s axis conversion once. Compare against a known-size object.
5. Verify before production
Inspect the horizon, origin, material appearance and bounds. Check that the collider aligns with the visible scene and that camera movement remains smooth on your target hardware. Reduce preview density when necessary. A splat is not automatically a navigable game level: add collision handling, controls and gameplay in your own project.
FAQ
Can I import SPZ as an ordinary mesh?
No. Gaussian splats need a compatible splat decoder and renderer. For a mesh workflow, choose the GLB export. Verify format and version support in the renderer you use.
Which assets can I download?
Public panoramas are available to everyone. Full-resolution splats and meshes are restricted to the author with the required paid plan. High-quality mesh export requires Pro or Studio and additional credits.
