Unreal Engine 5.8 plugin

Turn any place on Earth into a game-ready Unreal Engine landscape.

Real-world heightmaps — fully inside Unreal Engine. Pick a location, draw a square, hit ⛰ Import. TopoFetch downloads real elevation data, enhances it, and builds the complete Landscape actor in your level: exact 1:1 scale, real satellite imagery, roads, rivers, buildings. No values to copy, nothing to configure.

How it works

Three steps. No copy-pasting coordinates, no manual import.

1

Pick a place

Search or pan the satellite map anywhere on Earth, right inside the TopoFetch tab.

2

Draw a square

Drag an exact square over the area. Move it, resize from any corner — middle-mouse always pans.

3

Hit ⛰ Import

The Landscape actor appears in your level — scaled, textured, and ready to fly through.

Everything the pipeline builds for you

v2.1 — built and assigned automatically, undo-able, works on World Partition maps.

One-click landscape

Heightmap, exact 1:1 scale (X/Y/Z), sea level at world Z=0, recommended component layout, material assigned automatically.

Satellite texture

Real satellite imagery reprojected to map exactly 1:1 onto the landscape. Auto-created material instance per import. Up to 8K on Pro.

World Capture

First import becomes your project's geo-anchor. Every later import lands at its true real-world offset automatically — expand the world any day.

Real-scale buildings

Every OpenStreetMap building as a real-scale volume — real footprint and height, round→cylinder, dome→sphere, else box. Organized in its own outliner folder.

Terrain quality

Copernicus GLO-30/90, SRTM, NASADEM, ALOS, USGS 3DEP sources. Hydraulic-erosion detail, flattened roads, sculpted rivers & lakes, real ocean bathymetry.

Modern dark workflow

Unreal-editor style UI, hover tooltips, collapsible sections, per-project import history, and a Cancel button that aborts cleanly.

Unique to TopoFetch

Build a whole world, one tile at a time.

Your first import lands at your level's center and becomes the project's geo-anchor. Select the neighbouring area any day after and hit Import — TopoFetch places it automatically at its true real-world offset. No manual alignment, no drift. Keep going until the whole region is captured, at real scale, from real data.

Editor plugin	Python Editor Script Plugin (built into Unreal, just needs enabling)
Data access	Free OpenTopography API key — see above

Docs & FAQ

Install

Copy the TopoFetch folder into YourProject/Plugins/TopoFetch.
Open the project. If prompted to rebuild modules, click Yes (one time per engine version).
Enable the Python Editor Script Plugin if asked, then restart.

Use

Tools → TopoFetch opens the dockable tab.
Follow the welcome screen to add your free API key.
Search a location, draw a square, choose your settings, click ⛰ Import.

FAQ

Do I need to pay for elevation or map data?

No. All data sources used are free and public; you only need your own free OpenTopography API key.

What's the difference between Free and Pro?

Free caps the satellite texture at 1K resolution. Pro (via Fab.com, $49) unlocks up to 8K. Every terrain, building, and World Capture feature is identical in both.

Does it work on World Partition maps?

Yes — the landscape is automatically split into streaming proxies. Large imports (8K) can take a few minutes at that step.

Can I still get the raw heightmap PNG instead of an auto-built landscape?

Yes — untick "Build the landscape automatically" in the Output section and TopoFetch produces the PNG + report exactly as before.

Which engine versions are supported?

UE 5.0+. Prebuilt binaries ship for 5.8; other versions compile once, automatically, the first time you open the project.

About

TopoFetch is developed by Hamed Tybi. It grew out of a simple frustration: turning real-world terrain into a usable Unreal Engine landscape used to mean juggling GIS tools, manual reprojection, and copy-pasted scale values. TopoFetch collapses that into one click, inside the editor you already have open.
