It's the model at Renderosity. If I remember the creator of it mentioned that he generalized it. I remember spending an entire summer building a model during a summer vacation when I was a teenager. And I started working on an Artisan wooden model 10 years ago - soon I will retire and if my eyesight and hands can stand it, I will put more time into it.
DandelO, sorry for stealing thread here - RAF, two more things to consider - if you wish to use models in TG2, be sure to read posts by Klas. He has a utility that runs against mtl files and it creates a tgc file that TG2 can input (with many mtl fixes and improvements). And dig deep into DandlO technology - His planetary grass shader is a favorite.
