Hello Oshyan,
I was using GISD in the standard version, not AO alone. There is no post processing here, sun and light settings were the same. Path tracing on surfaces makes renders more constrated (and more realistic).
How many bounces are used in the path tracing engine ? Do you plan to add the possibility for the user to choose the bounce number in the future ?

Strange, I wouldn't think path tracing would affect brightness of the vegetation in that way (it hasn't in most of my tests). The one thought that comes to mind is if there is notable reflectivity on any of those plants, then the path tracing system would treat those differently (there is a new soft reflection algorithm that is enabled with PT). That could explain it.

The number of bounces may be user-adjustable in the future. I think it's currently 6.

Could it also be reflective vegetation with somehwat symmetrical faces to leaves and such from generation that light bounces between them in addition to enviro light and sun? Creating specular like brightness

The specular model for path tracing mode is just completely different. It may be taking into account those aspects you mention, when the normal model doesn't, I'm not sure. But I do know it's very different (and, as I understand it, generally more realistic/correct).

Perhaps transluscency (which is always enabled for grasses) has to do with it also. Path tracing renderer will calculate it much more precisely.

certainly more realistic....if I ever climb out of this money / house hole I gotta upgrade for sure. My mouth waters when I see these path traced renders....

Yeah, it's a very serious improvement to the beauty of final renders. Much more realistic. I hope it's released in freeware this year or early 2019.

As a primary and general rendering method (and not a specialized feature more suitable for licensed versions) it will indeed be available in the free version once 4.3 is released officially.

Even without the path-trace it's a stunning image!  But the final result is a huge incentive to upgrade: well conceived and executed, an exquisite image!

That's a lovely image Antoine. I'm curious how you find Grove 3D, i've heard good things about it and was wondering how well it actually works?

Unfortunately there's no demo version so it's quite hard for me to understand how well it works\performs. What's the workflow like in getting it from Blender into Terragen?

Cheers

In my personal opinion and for my needs,  I am very satisfied with The Grove, it creates very realistic and natural looking trees in just a few clicks. As for the twigs they sell, they are very good too.  Twigs are made of real meshes and they are applied to the tree by particles system.
For use in Terragen, I first apply a decimate geometry to the twig as much as I can, if not the tree could be so heavy in polygons that it would be impossible to import and handle in Modo and Terragen. However, I couldn't find a way to do that with connifer twigs because thay are made of hundred of needles
After that, I export the tree from Blender in fbx format, I import it in Modo 903 and from there I export the tree in obj format. There are some manual adjustments to make in Terragen (alpha, transluscency, specular, colors, bumps...)
So yes, for what I want to achieve, and at my level, The Grove is exactly what I need.

Does Blender not natively export to OBJ?

It does, but not with the twigs that has been placed using particles system.
