According to the Newsletter, Terragen 4.6 is about to be released. This being the first big update for the advanced 3D landscape desktop software in two years.
* Windows now has .VBD export (was previously Linux only).
* Export clouds in .VBD for use in Blender etc.
* Better sRGB support.
* Better .FBX import, better .FBX export compatibility with Unreal Engine.
* Now with import and export of population caches as XML, as well as binary.
* Rendering speed improvements, faster Preview renders.
* Pro users get an experimental pipeline for RPC integration with other third-party tools.
* An open-source RPC Python module, so you can write Python scripts enabling other software to ‘talk’ to Terragen.
* Geolocation (aka “Georeferencing”) is said to become free in the Terragen 4.6 Free (aka Learning Edition, Non-Commercial). So far as I can tell, this is about aligning tiles side by side, rather than grabbing a DEM landscape tile from a user-friendly Google Earth style world-browser.
Still supports Windows 7+, and the update is free. Terragen 4 Free is free, and then currently Terragen 5 Creative is $299, the Pro is $599. A Mac version is coming soon, and a fun nodes-free ‘sky making’ Terragen Sky tool is also coming in December 2022.
