Everything I've seen sofar from Terragen shows it is heading in the right direction, moving very fast, and this is why I'm less patient to get it fully integrated with the rest of the tools.
The latest vdb export is a fantastic step, the subscription pricing is definitely a great gesture.
I need a great Tree modeler, I'm now heavily testing SpeedTree, and it has astonishing capabilities compared to 2 years ago, I just want to use all of SpeedTree inside Terragen.
By the way there is a SpeedTRee Engine for Clarisse being developed. Coming in a few weeks, But clarisse doesn't have atmospheres, skies or clouds.
Terragen needs to integrate with Clarisse perfectly, then I'm ok to forget about the speedtree story.
A software with limited integration in the VFX pipeline, will die young. We don't want that for Terragen.
