You're welcome ;-)
I totally don't get it how this could be rendered in 2 hours. Yes, without the populations I could easily imagine a 2h rendertime.
Always when I render populations it takes ages and ages to render because the lack of culling/clipping in the current renderer.
I understand you've split-rendered this image? Did you use GI then?
What were the settings? Just wondering, hope you don't mind all these questions.

I don't mind at all. Here are the answers:
- The render detail was 0.8
- Gi was 1/1
- the atmosphere had cloud 2 layer, but you can effectively see only one. It had a 2D cirrus and then the low hanging 3D. The density was just 0.002 and the accelaration cache was set to "more acceleration" - which is ok for those type of clouds. Effectively the layer needed just 25 samples for quality 1.
- The trees have been simplified: I removed all leaves and also quite a few branches. Still the object quality was set to "very high" in the populator.
- The scene has effectively very few trees in the foregound. Most tree instances are very far away, hence render very fast.
- As I mentioned before, I have very few shaders, no displacements, no reflections
- And yes, I've cropped the render in two halfs, rendered each half with one instance of terragen and 1 core each, and assembled the results afterwards. I usually let the two halfs overlap. So one render (from left to right) is set to [0;0.55] and the other half to [0.45;1]. In general this is enough for the GI not to mess up. But now that you mention it, the overlap for this image wasn't quite enough, so I had to do a little postwork to make the line between the two halfs disappear.
Hope that helps,
