[Opensim-users] Good Resource for Models, Buildings, Terrain, etc?

[David Merel]

Does anybody know a good resource where i can download and possibly
import buildings, cars, trees and other models? I would like to
populate my OpenSIM and even though i plan to build some things from
scratch i was wondering if there was a way for people to start off
with some samples or ways to import so that i dont have to re-invent
the wheel for everything.
Thanks in advance
