Acer tree model made in 3ds Max 2017.
Exported to FBX and Obj with three materials. One for the trunk and two for the leaves(inside and outside).
Textures for the leaves have alpha channel and 10000x10000 resolution, textures for the trunk are 8192x8192 pixels.
Model has 350000 triangles count.
Leaves consist of two meshes with flipped normals places at the same position. One mesh for the outside leaves and another for the inside. You can delete inside part for reducing polycount twice. In this case material for the leaves must be doublesided for the saving density of the leaves.
