Terragen 2 added cache-based GI, which simulates multiple scattering but often lacks detail. Terragen Classic had a simple ‘darkening’ parameter to artificially control the rate of self-shadowing, which became ‘light propagation’ in later versions. Most renderers try to approximate these effects in ways that often fall short of producing photo-realistic results. But if we try to render optically dense clouds with only single scattering then not enough light reaches deep into the shadows and it’s difficult to consistently achieve all of the subtle effects that make clouds look like clouds. Thin clouds are easier to render because they can be approximated with only one scatter (because most light exits the cloud after the first scatter). Light reaches deep into the shadows and beautifully illuminates the clouds in ways that a single-scattering simulation does not. This gives rise to phenomena such as bright cloud centers that contrast with dark edges (especially when the sun is behind the camera) and inter-reflections between masses of cloud at scales both large and small. In the real world, large, dense clouds of water droplets scatter light many times, absorbing almost none of the light as it is scattered. Next to this, Planetside is developing a new lighting model for clouds that simulates multiple scattering without using the GI cache. We think this will revolutionize the way you use Terragen. In all cases the ray-traced preview gives quick and responsive feedback, allowing you to iterate faster than ever before. This includes also the work with complex cloud and lighting setups. The ray-traced preview mode supports Terragen shaders, lighting, and atmospherics, including clouds with volumetric shadows (aka “god rays”).
One of the new features included in Terragen 4 is a ray-traced real-time preview with progressive refinement. So far Planetside unveiled just some of the features and enhancement present in the next version together with some pre Alpha images and videos, but it looks that the preview features presented by the company are more than impressive.
TERRAGEN 3 TUTORIAL SOFTWARE
At this moment the company is preparing a new major release of Terragen 4 making the software faster, more interactive and easier to use.
TERRAGEN 3 TUTORIAL TV
The render capabilities were already tested in blockbusters like Star Wars: The Force Awakens (yes, the new one), TV shows, games, VR environments, museum exhibits, documentaries, and more. What is Terragen? Terragen is a complex software solution for generating realistic landscapes, skies or other natural environments.
TERRAGEN 3 TUTORIAL UPDATE
It has been more than a year when Planetside Software, the leader in high quality landscape visualization, released an update for Terragen 3 updating it to version 3.2.
