A tree V3 with ground, grass, stones and a pond. You can check out my profile for more versions. This is made in blender and rendered in cycles. The whole scene is quite low poly so after baking and a few optimizations you can also use it in your games. The whole scene uses just procedural textures, so you can bake it to whatever resolution that you want.
The plugin was only used for the tree (blender sapling addon). This 3d model is UV unwrapped except for the tree. You will also get baked normals for the rocks (4096*4096)
