own your site in unreal.

The Mantle Place Importer is a first-party Unreal Engine plugin that lands your purchased bundle as an owned, editable, georeferenced native Landscape or mesh. Downloaded once, imported from disk, never streamed.

Draw an area of interest on the Mantle Place globe, buy it once, and bring it into Unreal Engine as a real Landscape, terrain mesh, or static mesh with the aerial imagery already draped. The importer reads owned files from your disk: there is no access token, no runtime connection, and no subscription that can lapse under a shipped project. It is the familiar plugin form factor with the opposite substance: your site belongs to you.

The importer ships from your vault download page with any bundle you own, free bundles included. A public plugin listing is on the way; until then the vault is the canonical download.

the importer

one plugin, owned output

content only

No C++, no compiling

A content-only plugin: it loads in Blueprint-only projects and needs no compilation step. Validated on UE 5.7, forward-compatible with newer releases.

one button

Import in one click

Pick the bundle, press import, and the terrain, imagery drape, and georeference land together. The same code runs headless for batch imports.

fail closed

Placement is checked, not hoped

Every import runs a placement check and either reports green or refuses with the offending numbers. The whole import is one transaction: a single undo removes it cleanly.

no geo math

The manifest carries the transform

The bundle manifest holds the exact Landscape transform, the height mapping, and the flat UTM georeference at your site centroid. The plugin reads it and does no coordinate math of its own.

own it

Offline and re-importable forever

Once downloaded, the bundle lives on your disk. Re-import it offline forever: no token, no phoning home, no platform dependency in the editor or the packaged build.

editable

Real geometry, not a backdrop

Terrain arrives as a sculptable Landscape or a Nanite-ready mesh. Paint, carve, cut a pad, and build on it like any other geometry.

what arrives

inside the bundle

  • A 16-bit Landscape heightmap (PNG), scaled and placed to your exact extent
  • An aerial imagery drape (PNG), aligned to the terrain on import
  • A Nanite-ready terrain mesh (GLB) as the static-mesh alternative
  • Full-resolution DEM and imagery rasters (GeoTIFF, COG), plus the complete format catalog for your other tools
geodesy

placed right, provably

  • Flat projected georeference with the origin at your site centroid (UTM)
  • Orthometric heights (EGM2008) in meters, ready for real-world elevation reads
  • The exact transform ships in the bundle manifest; the importer applies it verbatim
  • A fail-closed placement check refuses a wrong landing and reports the numbers that prove it
questions

frequently asked

Do I need an account or token to import?

Buying happens on the web and your vault holds the files. The import itself reads owned files from disk: no access token, no runtime connection, nothing that expires.

Does anything stream at runtime?

No. The importer never streams from Mantle Place and never re-processes the pipeline in-engine. A request for different processing is a new web order; the files you own keep working regardless.

Which Unreal Engine versions are supported?

The importer is validated on UE 5.7 and is a content-only plugin, so it loads in Blueprint-only projects without compilation. Newer engine releases are forward-compatible.

Where do I get the importer today?

From your vault download page, alongside any bundle you own. Free bundles include it too, so you can run the whole flow on a small site before spending anything.

Can I browse my vault from inside the editor?

Not yet. Today you download from the web vault and import the local bundle; an in-editor vault browser is on the roadmap. Ownership does not change either way: the files are on your disk.

How does this compare to Cesium for Unreal?

Same plugin form factor, opposite substance. Cesium for Unreal streams tilesets at runtime and is excellent for planet-scale context; Mantle Place delivers owned, on-disk data you import once and keep. The full comparison is on the compare page.
