and another.

Nice Work. Render looks dreamy. I like the color of the plants.
Ten story building? No didnt think of that.
Render comes from Kerkythea.
Trees are from a free Tree making software.
First i rendered the tree models with Kerkythea and make PNG images
of the trees to place in SketchUp.
Here's a tree PNG :
This is one of my best settings of been using. Just press Generate many times
for random trees. If any body can find better settings let us know.
...and here's the result. Nothings perfect, UV's are not setup correctly on any of
the trees.
Frederik,
I don't know yet if im going make any model library's, it's to early to say.
Ive only have 9 normal looking trees.
and here's another, i added some toes to the base of the tree with blenders
sculpt mode tools.
Here's an 11,000 polygon tree. Small enough to work with SketchUp.
Using a small laptop, 797 MHz, 512 MB of RAM.
Two more renders. Imported trees into SketchUp and separated some twigs
from the branches and trunk.
Populated the twigs with the same leafs i used for the hedges.
