Terragen 4.6 Release builds are now available for Windows and Linux. The Mac version will follow soon. 4.6 is jam-packed with new features and improvements.

Georeferencing for Everyone
  • Georeferencing capabilities are now enabled in all editions, including the Free and Creative editions, not just the Professional edition.
OpenVDB Export
  • Terragen VDBs in Unreal Engine
  • Terragen Sky and Terragen VDB in Blender 3D
  • OpenVDB export is available on Windows and Mac (previously it was only on Linux) with a license for the Professional edition or Creative edition. A VDB file can be exported from the command line (in the Professional edition) or from within the Node Network UI.
  • Documentation:
FBX Improvements
  • The FBX importer works with FBX files that use non-default coordinate systems, such as those exported from Unreal Engine.

RPC and Python APIs
  • We're developing an RPC (remote procedure call) system for Terragen, so external programs can query a running instance of Terragen for information about the project, make changes to nodes, create nodes etc. Applications can talk to Terragen over TCP (JSON-RPC 2.0 over TCP, to be exact). There is also a Python module which provides an easy-to-use API, with high-level functions such as root(), children(), delete(), save_project() and so on. Standalone Python programs, as well as scripts running in other applications, can import this module to interact with an instance of Terragen.
  • The RPC feature is currently designated “Beta” and is available in Terragen 4.6. A license for the Professional edition is required.
  • For complete documentation on the RPC system, look here:
  • The RPC Python module is available on GitHub:
XML Format for Importing and Exporting Instance Data
  • Population caches can be saved to (and loaded from) an XML-based format by choosing a filename with ".popxml" extension.
  • You can use .popxml files to cache your populations instead of binary .pop files, but their real power comes from the fact that they can be loaded and saved by third party scripts to share data with other applications.
Better, Faster Previews of Clouds and Atmosphere
  • We improved the 3D Preview's level-of-detail calculations for voxel buffers in clouds. The preview now uses a view-dependent minimum voxel size so that clouds nearer the camera are more likely to be rendered with the highest voxel resolution provided by the cloud, while clouds further away are more likely to be approximated. There are two modes to this. The first pass of the RTP, and all passes of non-RTP previews, use a low-detail mode which is designed to be fast (fewer voxels need to be cached before you see results). Subsequent RTP passes use a higher detail mode which is closer to final renders but may take longer to cache voxels before you see the results.
  • The max ray depth has been increased for the GI approximation used in RTP for Planet Atmosphere.
  • Experimental: The RTP attempts to approximate GI for Cloud Layer V2 in the same way that it's done for Planet Atmosphere.
Next month we will introduce a brand new product: Terragen Sky.
  • Terragen Sky comes with a fresh new UI and has a streamlined workflow for creating and rendering skies — including 360-degree HDRI output. It can be used as a standalone app or as a sidekick to Terragen 4. All the node wiring is tucked away out of sight so you can focus on exploring and creating without distraction. It’s time to bring the fun back!
  • Early Access builds of Terragen Sky will be available to anyone with active maintenance or subscription on Terragen Professional or Creative. So if you’re not sure whether to renew your license now to get 4.6 or wait to see what Terragen Sky is all about, don’t worry. Either way you won’t miss out.
