Terragen 4.3 has arrived and with it comes another set of important new features and changes, most notably realistic one-click cloud movement and shape "evolution."
The 4.3 update is free to all users who have current Maintenance. Terragen has also updated the Free Non-Commercial edition.
To download the new version or check your Maintenance status just use the Check for Updates option in the Terragen Help/Application menu. Note that Terragen needs access to the Internet for this to work. Alternatively, you can login to your account on our website and go to the details and downloads for your most recent Terragen purchase.
Here are the most notable additions.
Simple animation controls for Easy Cloud
OpenVDB cloud volume export
You can now export Terragen cloud shapes to the open source OpenVDB format, compatible with a wide range of other applications. This feature is only available on Linux at this time.
Reduced render times for Easy Clouds and more
Shaved about a third off calculation times for the colour generated by Power Fractal Shader V3 (colour/value, not displacement). This makes a big difference to render times for Easy Cloud, for example, and is expected to speed up many scenes that use the Power Fractal Shader.
Deferred Shading render method
This new rendering mode improves anti-aliasing of textures and lighting (e.g. soft shadows) on terrain and other displaced surfaces. May render faster or with higher quality than normal micropoly rendering. Image quality and render time depend on anti-aliasing settings.
New adaptive anti-aliasing options
Experimental new render anti-aliasing modes allow for higher quality renders with lower visible noise in equivalent render time. Higher levels of adaptivity are also possible, providing lower render times for equivalent quality in appropriate situations. These new options will be particularly important for the upcoming path tracer rendering method (available in 4.3 in an experimental state).
New Sample Rate render element
Useful for optimizing sampling settings with adaptive anti-aliasing
Path Tracing on surfaces
Path tracing provides increased realism in lighting interaction of objects and terrain. This is the fundamental rendering method employed by most major modern renderers. This rendering method will be slower than normal rendering, and may have some differences in material handling (e.g. specular surfaces). We don't recommend using this for production at this time.
Numerous fixes and improvements to rendering
These improvements together result in more consistent and high quality render output for many scenes.
Plus, fixed crashes, possible memory leaks, and improvements to FBX imports and UI responsiveness.
