Start from noise and erosion, shape the result by hand, look at it as a full 3D world with sky, sea and weather, then export something your engine, renderer or printer can use.

Overview

Build eroded landscapes, walk around in them, and export heightmaps, meshes, skies and print-and-play maps.

Terrain Generator is a standalone desktop tool for building landscapes. It starts with a fractal base with ridged crests, then runs a water simulation that cuts real drainage into it. Thermal erosion, river incision, terracing and domain warp are separate steps you can reorder.

When the sliders aren't enough, there is a node graph with Voronoi cells, fault scarps, fold ranges, impact craters, mesas, karst towers, volcanoes, and blend, mask and remap nodes. About 45 presets cover mountains, coasts, deserts, karst, plains and volcanic land.

The viewport shows the finished look, not a proxy. Walk mode drops you into the landscape as a first-person avatar, so you can walk or swim across it.

Generate

Noise, erosion and landforms, each as its own step you can reorder.

  • Noise and droplet erosion that cuts real drainage
  • Thermal erosion, river incision, terracing and domain warp
  • A node graph for craters, mesas, karst towers, volcanoes, fault scarps and more
  • Import a heightmap as a node and build on top of it
  • ~45 presets grouped by landscape type

Shape it by hand

A non-destructive curve stack over the generated land.

  • Draw a line to flatten a road, raise a ridge or dig a trench
  • Cut-only and fill-only modes, four falloff profiles, width and feather per curve
  • Re-roll the terrain underneath and the curves still hold
  • Worlds up to 8 × 8 sectors, 10 m to 20 km per sector edge

See it before you export

The viewport is the final look, with sky, sea and weather.

  • Four authorable material layers with noise-broken transitions
  • Sea with waves, foam, wet shorelines, caustics and an underwater look
  • Volumetric clouds, cloud shadows, haze, sun shafts and ground mist
  • Procedural grass, rocks and pebbles that thin out with distance
  • Walk mode: walk or swim across the site in first person

Export anywhere

Maps, meshes and skies, with ready-made presets for the big engines.

  • Presets for Unity, Unreal (Z-up, centimetres), Godot and Blender
  • One mesh, one per sector, or streaming tiles with an LOD ladder and skirts
  • Equirectangular panoramas, cube maps in five layouts, six-face skyboxes
  • Up axis, handedness, scale and UV layout are all yours

Tabletop maps

A full print-and-play board export for your next campaign.

  • Hex (pointy or flat top) or square grids
  • A4, Letter, Tabloid and A2 multi-sheet layouts
  • Coordinate labels, legend, compass, scale bar, elevation key and movement cost
  • Fantasy-antique, blueprint, contour ink, cartographic or phosphor-terminal styles
