Topographic Map Editor that Renders Custom Heightmaps

  • Supported Platforms
  • Supported Engine Versions
    4.23 - 4.26
  • Download Type
    Engine Plugin
    This product contains a code plugin, complete with pre-built binaries and all its source code that integrates with Unreal Engine, which can be installed to an engine version of your choice then enabled on a per-project basis.

The TopoTool takes your topographic map inputs, drawn via splines on the Editor Utility Widget, and renders them into a binary heightmap file. That heightmap file (extension .r16) can then be loaded into the Unreal Engine Landscape Tool for creation as a fully editable landscape geometry.

The Tool provides inputs for peaks and valleys, topographic lines, rivers, and roads.

On Render, the Tool gives the user the ability to add realism via Perlin Noise and Hydraulic Erosion.

Notes:

To begin, right click the TopoWidget and select "Run Editor Utility Widget".

This is a tool that is run in the native Unreal environment and does not need to have a game or level active to use.

Settings and Help provide options for color changing and keyboard shortcuts.

Generate is the button to bring up the render window to choose where the file is saved.

Topography can be saved and loaded later, as it utilizes Unreal's save game functions.
