Check out what's new in the latest update to Terragen.
Planetside Software has recently released Terragen 4.5, a new version of the team's landscape-generation software.
The biggest update is the next iteration of the toolkit’s default shader. It is said to better support PBR workflows and there are new metalness controls, plus support for the GGX model for specular roughness. The new version also adds support for key color management standard OpenColorIO in the Professional edition.
There's a new Rayleigh phase setting in the atmosphere system which allows users to generate more realistic atmospheric light scattering.
