TerraRay is an easy-to-use terrain rendering suite made for Mac OS X. Create stunning artwork without learning a complicated and expensive 3D application, TerraRay allows you to create realistic landscape images with just a few clicks while offering many advanced features for you to explore.

Advanced Renderer

TerraRay features a state-of-the-art renderer which can simulate very realistic lighting using a global illumination algorithm. Every surface in your scenery reflects light onto other surfaces as in reality.

Simple yet powerful editor

The built-in editor has been built with simplicity in mind. You do not need to read a manual to create stunning scenery with TerraRay. You can draw an elevation map using the integrated editor and define where valleys or hills should appear in your scenery.

Flexible Materials

Create any type of material in TerraRay you can imagine: Earth, Sand, Rocks, Ice, Snow, Grass, Mud…TerraRay comes with many preset materials you can assign on any part of the terrain using different material layers.

Custom Models

TerraRay allows you to place models directly into your scenery. You can use models from the built-in library like trees, houses or cars or import custom models using the commonly used 3DS file format.

Volumetric Clouds & Sky

Since Version 6, individual volumetric clouds or cloud clusters can be placed in a scene. You can control the density, size, sharpness, height and many other settings individually for each cloud cluster. Clouds fully interact with your scene, for example by casting shadows.

Volumetric Fog

Using the volumetric fog in TerraRay creates stunning visible rays of light in your scenery. The volumetric fog works with any number of light sources and you have fine grained control over the density and height of the fog.

Post-Processing Effects

The flexible post-processing effects available since Version 5.1 can vastly increase the realism of your scene. After rendering your scene you can apply near and far depth of field blur including depth tinting.


TerraRay can simulate the natural erosion process using complex algorithms. You can either apply the erosion process to your whole terrain or to just some regions.


With TerraRay, you can create very realistic rivers, lakes or an ocean. Control the wave size, height, turbulence, the absorption color, the reflection color and many more aspects.


Place grass, leafs or rocks anywhere you want in your scenery. Simply add a plants or rocks layer with a single click and use brushes to define where grass should grow in your scenery.

Fractal Terrain Generator

TerraRay comes with a Fractal Terrain Generator which allows you to create stunning terrains with just a few clicks. Furthermore, the Fractal Terrain Generator comes with many presets you can choose from.

Autogenerated Materials

Since Version 4, TerraRay supports automatic texture generation. You can simply apply one of the many presets to your elevation map and TerraRay automatically generates the appropriate texture maps.

System Requirements

TerraRay requires a Mac with OS X 10.6.8 Snow Leopard or higher.
