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.
Whether you need beautiful results quickly, or absolute control of every detail, Terragen 3 gives you the tools you need for unparalleled skies. Achieve beautifully realistic sunsets in seconds by simply adjusting the sun angle, with a real-world atmosphere model taking care of the rest. When you're working with a fully simulated global environment, objects and effects interact like you'd expect them to, so sophisticated effects like "god-rays" or even solar eclipses are remarkably easy to achieve.
