How to import real-world terrain into Unity

A real site in Unity as owned meshes — no streaming SDK, no token, just the standard import pipeline.

To import real-world terrain into Unity you either stream it through an SDK like Cesium for Unity or bring it in as owned geometry. For a specific site, owned is simpler: draw the area on Mantle Place, buy the bundle, and add the terrain to your project — the OBJ imports natively, or use the GLB through a glTF importer package. The aerial imagery arrives draped as the mesh texture, and the surrounding buildings ship as a separate glTF layer. If you want a sculptable Unity Terrain object rather than a mesh, the bundle’s heightmap can drive one, though Unity’s terrain importer expects RAW, so plan a conversion step. There is no Mantle Place Unity plugin, and none is needed — standard files through the standard pipeline is the point.

step by step

how to do it

  1. Draw and buy

    Define the area of interest and buy the bundle; it downloads to a permanent vault you can re-download on every machine that needs it.

  2. Import the mesh

    Add the OBJ terrain to your project for native import, or install a glTF importer package and bring in the GLB with its materials intact.

  3. Check scale and orientation

    Confirm the import scale is meters and the up-axis matches Unity’s Y-up convention before placing gameplay or lighting.

  4. Optional: drive a Unity Terrain

    Convert the heightmap PNG to 16-bit RAW and import it as a Unity Terrain heightmap when you need a sculptable terrain object instead of a mesh.

  5. Build the scene

    Drop in the buildings layer, add colliders and lighting, and treat the site like any other geometry in the project.

questions

frequently asked

Do I need Cesium for Unity to get real-world terrain?

No. Cesium for Unity streams global tiles at runtime and is the right tool for planet-scale work. For one owned site, importing a bundle as plain meshes is simpler and carries no token or connection.

Will the terrain work in builds without a connection?

Yes. The site is ordinary geometry and textures baked into the build — nothing streams, nothing expires, and the packaged project runs fully offline.

Can I get a sculptable Unity Terrain instead of a mesh?

Yes, via the bundle’s heightmap. Unity’s Terrain system imports heightmaps as 16-bit RAW, so convert the PNG first; after that the site behaves like any sculptable Unity Terrain.
