Terragen 3 users, we have a new update for you. Terragen 3.1 is here!

To get Terragen 3.1, use the "Check for Updates" feature from the Help menu in Terragen 3.

If you render on the Mac or on Linux, there may be some differences when you render in 3.1. There were some differences between Mac/Linux and Windows renders, so we've corrected the Mac and Linux versions to match the Windows renders.

The main themes for this release are "speed", "objects" and "georeferencing". Here are some of the highlights for me:

The 3D Preview and Shader/Heightfield Previews are now faster than ever before, as all phases of the preview are now multi-threaded and some other aspects have been optimised.

Atmosphere and cloud rendering is now significantly faster in many cases. Thanks to Danny Gordon for the scene that helped me to find the problem here.

There are other cases where 3.1 now renders faster.

One of the most exciting new features in 3.1 is the ability to anchor populations to other objects, not just terrain. In other words, you can populate on an object. If you haven't seen it already, check out the live demo that Oshyan gave earlier in the month, showing some of the new things you can do with the new population features, as well as many other new features in 3.1:


Terragen 3.1 has two new objects: Cube and Octahedron. These are "displaceable objects", like Disc, Lake, Plane, Planet and Sphere. They can be positioned, rotated and scaled. Corners are rounded using a "Round radius" parameter (Cube) or "Roundness" (Octahedron). The roundness may be important when applying displacements.

Spheres can now be rotated. If you scale a sphere non-uniformly (i.e. stretch the sphere), this can be very useful. The Sphere also has some other options that are important when the scaling is non-uniform, and you can now rotate and scale in the 3D Preview.

There are lots of other improvements to objects including double-sided rendering of Discs and wireframe previews of all the displaceable object types (although the wireframe doesn't show displacements from shaders). The download page has a complete list of all the changes we've made.

Jo has developed a new "Geog Image Map Shader" node which can load georeferenced images. It can be used as a colour shader or a displacement shader. This is great for aligning orthoimagery with georeferenced DEMs. He's also added a new option to both the Image Map Shader and the Geog Image Map Shader called "Use alpha/transparency for direct blending". This blends/masks the image with underlying surfaces based on its alpha channel (or any transparency generated through keying), without having to mess about with masking shaders. If the alpha channel needs to be inverted, no problem; there's an option to do that.

I've made some small but useful improvements to the Heightfield Shader to help out with georeferenced terrains, or even just terrains that are positioned far away from the origin or the top of the planet.

Jo has written a new back end for the Painted Shader to replace the less-than-ideal system that I'd written earlier. The new back end should greatly improve stability with large amounts of painting. It removes problems with doing things like painting from the terrain onto the sky. It also fixes the problem where you would do a lot of painting, save the project and then find TG would crash when you tried to open the project.

I've fixed some rendering problems with spherical camera, particularly near the top and bottom of the image. Spherical renders now render faster too.

There's a lot more to this update, which you can read about on the download page. To get Terragen 3.1, use the "Check for Updates" feature from the Help menu in Terragen 3.

Good news here  :D

Thanks a lot Matt and all the Planetside Staff


THis just sounds great! Thanks Guys. And the testers too. Your all good stuff 8)

Hi MAtt. Sorry to say, but the auto update in the help menu is saying no new updates as of the time of this post.

Thanks All at TG great update.  Look forward to playing with it.


Try checking again now. I just corrected the Mac update.

Matt thanks for the update.It looks very nice!

Nothing much important but i had an older build and waited for this one but i could not update to the last (3.1) before installing the 3.0.1 build.


Is the upgrade any different from last alpha?


Ulco, it's the second release candidate, build

Well, there goes my weekend...  8)

And I just picked up the animation version yesterday, so may as well scratch every weekend until the spring, too.  But hey, it's Winter, I live in Canada, we stay in a lot, anyway.  :P

Thank You! The pace of TG development seems to be accelerating rapidly,  and is much appreciated. Now if you could just institute the 36 hour day option maybe I can figure out how to learn all these new treasures. Once again, thanks!


Thank you Planetside,   Having great fun.  ;D
