TerraRay is an easy-to-use terrain rendering suite for your Mac. Create stunning artwork without learning a complicated and expensive 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 simply paint 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.

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.

Realistic Clouds & Sky
TerraRay features configurable volumetric clouds. You can specify the cloud height, density, cover and size. Furthermore, you can control the sky turbidity, sun size and intensity and the general horizontal brightness.

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.

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.

TerraRay can simulate the natural erosion process using complex algorithms. You can either apply the erosion prices 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.

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.

TerraRay uses an advanced path tracing renderer to simulate very realistic lighting. The flexible elevation map editor allows you to easily create canyons, islands, beaches, mountains with just a few clicks. Custom materials can be assigned to any part of the terrain using the built-in material editor. Add vegetation and rocks to the scenery and hit the start render button to create stunning images easily!

A great introduction to 3D terrain building

Prior to discovering TerraRay I'd used a number of the other mainstream 3D terrain apps. They're all pretty complex, expensive and not immediately approachable for beginners. But TerraRay makes the basic concepts of terrain generation very accessible (creating a terrain, editing it, adding lighting and material layers, etc.) while offering some pretty unique, attractive and easy to use tools for drawing the landscape, placing the camera and sun (among other things). Each new version brings improvements and fixes, which is good.

That said, I think TerraRay's biggest weakness is its lack of photorealism in the renders (especially in the clouds and water). The results are more along the lines of storybook illustrations or 1990s-era 3D, which is fine, but obviously for $15 you won't be matching the results you can achieve from the high end competition. Nevertheless, TerraRay is the perfect place to learn the basics of the art and vocabulary of 3D terrains and importing models, after which you can graduate to the major leagues.

I seem unable to contact the developer lately, which concerns me, but he's a good person and puts out other very fine software as well.

Great Fun & Easy to Use TerraRay

I was looking for something simple to use that can create 3d landscapes with buildings, trees, lakes and all that. There is always a tradeoff between power and usability. This product is easy to use, fast, intuitive and gives great results. It is not very expensive. It’s fun, bug free and I like it! Runs great on my Mac

Doesn’t work on High Sierra

This app looked ike just what I needed, but it doesn’t work at all on High Sierra on either my Macbook Pro or my iMac. The “preview” is just a white box that never changes. If I do a “Full Render” I sometimes see items I’ve tried to place, but other times not. Fairly useless app at this point.
