When that screen snip was taken, I was rendering a 360' environment panorama, broken up into four 90' still shots at 4096x4096.  They'll be used to texture a backdrop wall/skydome for a new Poser enviro playset.   Poser test shot attached of the enviro, though with only one instance of each type of tree. 

     The Poser Pro render test will be an animation with lots of special effects.

Poser 12, in feet.
