The model consists of 13 meshes. 1 mesh - Trunk(29,221 polygons) 1 mesh - Acorns (410,137 polygons)And leaves:3 meshes - Leaves Spring (9,997 polygons)4 meshes - Leaves Summer(12,700 polygons)4 meshes - Leaves Autumn(12,706 polygons)Total polygons: 474,761Only a tree with summer foliage: 41,921 polygonsOnly a tree with summer foliage and acorns: 452,058 polygonsOnly a tree with spring foliage: 39,218 polygons
For the foliage texture, I personally photographed the leaves. In total, the model uses 8 unique photographs of the leaves. Everything is packed into a .blend file. All the trees in the renders are the same: one single tree was used at different viewing angles, different varieties of foliage and acorns and with different proportions. The default height is 6 meters.
