TerraRoad is a Terragen road creator! It combines a heightfield exported from Terragen with an svg path defining a road shape, and creates a new heightfield with the road path leveled and smoothed. The tool also creates a variety of masks that can be used in Terragen for shading the road and shoulder.

Getting Started

To start using TerraRoad check out the installation and usage guides:


For information on the various settings available see:

Example Files

There are some example files included, a sample road svg, and a basic Terragen scene showing some ideas for using the resulting masks. To generate a heightfile from the sample scene, open the node 'Heightfield generate 01', and click Generate Now. Then right click on the node, and click 'Save file as' and save as an EXR image.
