Terragen was the first application to give artists a photorealistic Earth-like sky and sunlight simulation that was easy to use. Terragen 3 takes this much further with a spherical planet model, more accurate lighting, volumetric cloud and fog layers which can be controlled by custom shader networks, all rendered with multiple scattering and global illumination.Using TG3’s flexible node system you can create virtually any type of cloud, from wispy stratus and cirrus, to billowing cumulus and towering thunderheads, or even fog and mist.
Use unlimited cloud layers in your scenes for absolute realism. Choose between true 3D volumetric clouds, or hybrid “2.5D” clouds for faster rendering with less demanding cloud forms. Enjoy full control over the look of your clouds and atmosphere, including strength and color, red shift, haze density, and more, allowing you to create everything from the sublimely beautiful, to the out-of-this-world. Easily add stars, backgrounds, or even whole planets to your skies.
Terragen 3 features realistic sunlight(s), local, and spot light sources that can illuminate anything, ray-traced soft shadows, global illumination that enables full lighting interaction between surfaces, atmospheres and clouds, and ambient occlusion options. The quality of global illumination or ambient occlusion can be adjusted to find the right trade-off between render times and lighting quality. Our goal is to give you the right balance of lighting as quickly as possible, and then give you controls to tweak individual lighting contributions to perfect your art.
Terragen 3 allows you to create and manipulate highly realistic terrains, both heightfield and procedural. You can load existing heightfields to replicate real-world terrains and gain additional control by using a 3rd party terrain editor, or leverage the powerful built-in procedural functions to achieve global-scale terrains of nearly infinite detail, from the smallest pebble, to the largest mountains. You can combine the benefits of both terrain types in one scene, seamlessly. Even your heightfield terrains can be enhanced with the power and flexibility of procedurals. Using 3D procedural functions, go beyond the limits of heightfields to create truly realistic terrains, including sheer cliffs and even overhangs. Let your imagination run wild and create out-of-this-world terrains.
Terragen 3 includes support for rendering of complex, fully textured objects. Add life to your scenes with models of houses, trees, custom-designed rocks, or any other object. Objects can have an unlimited number of polygons and textures, constrained only by available memory. With your objects loaded into your scene, you can then apply any of Terragen 3’s surfacing effects and procedural shaders to enhance the look of your texturing.With a fully realized and powerful instancing system you can take your use of objects to a whole new level, and achieve highly realistic results. With Terragen 3’s “Populators”, you can add thousands or even millions of trees, rocks, birds, blades of grass, or any other object to your scene. You can instance any object that you can load. Terragen 3’s population system makes it possible to render literally billions, even trillions of polygons in a single scene!
With the optional Animation module, Terragen 3 becomes a virtual movie camera. Almost every parameter in a Terragen 3 project can be animated over time, not just the camera. This can be used to render dramatic fly-throughs, time-lapse effects and more. The Animation module includes a complete timeline and key frame editor, allowing you to see a visual representation of all animated parameters. A curve editor is also included where you can directly adjust key frame values on a plotted motion curve. You can key-frame parameters, import key frame values from text files and render image sequences from the user interface or frame by frame from a command line. Camera paths are plotted. You can preview fly-throughs in real time in the 3D Preview.
