Terragen2 is awesome. This is my first try at populating Fir tree which available for download (Using XFrog CL02a_Grand_Fir.tgo) at http://www.planetside.co.uk/terragen/tg2/tg2tp/index.html
I wish I know more on how to tweak light and material.
That is beautiful!
I think I've been there ;) Beautiful scene.
