I am interested in building a virtual world on Opensim (metaverse), and I am looking for some low-poly stylised forest models, such as trees, bushes, ferns and rocks. Free or to buy, it's a bit hard to find what I'm looking for, even when I'm willing to buy them.

I don't want any bushes or trees with blocks for foliage- either foliage cards or some other way of making the foliage look leafy.

Desired model and texture resolution anywhere between PS1 and Wii-ready assets. (I'm a bit indecisive)

I'm willing to consider untextured models/models with placeholder textures, but un-UV mapped models get a pass from me unless they're free.
