Create and manipulate highly realistic terrains based on procedural or heightfield data. Replicate real-world terrains by loading existing heightfields, or go beyond the limits of heightfields by enhancing them with procedurals to create cliffs and overhangs. Seamlessly combine the benefits of both terrain types in one scene, achieving global-scale terrain of nearly infinite detail, from the smallest pebble, to the largest mountains.

“Easy Cloud” models correspond to real-world cloud types such as Altocumulus, Cirrocumulus and others. For more control, Terragen’s node system allows you to create virtually any type of cloud, from wispy stratus to cirrus, billowing cumulus, towering thunderheads, mist and fog. Shading models simulate multiple scattering effects, resulting in cloud renderings that can be indistinguishable from photos.

Terragen 4’s physically based atmosphere model simulates not only the common Rayleigh and Mie scattering properties, but also the effects of ozone. Terragen provides all the flexibility you’ll need to light your scenes. Realistic sunlight(s), local, and spot light sources can illuminate anything, and cast ray traced soft shadows. Global illumination enables full lighting interaction between surfaces, atmospheres and clouds.

Built around a full planet model, both large and small-scale detail is possible in the same scene. Seamlessly and easily drop down from orbit to a realistically detailed ground level terrain.

Import terrains, texture maps, 3D models, cameras and light sources. Export volumetric clouds (VDBs), terrains (heightmaps, geometry and texture maps), cameras, and more.

Terragen is a renderer at heart. Micro-polygon displacements, instancing, physically based volumetrics, path tracing and PBR materials.
