Hello, I'm building an RTS game and need to find some models for the environment. However all models that I can find usually have too many faces for the scale of my game.

I would like to find for example tree models with max 100 faces that's not in the classic cartoony low poly style, but a realistic style. Preferably even with lower quality LOD models.

Could someone point me in the right direction or give me some good search terms?
