scots pine trees package Low-poly Model 3D

this is a collection of 9 low poly pine tree models. modeling in 3ds max 2015.
sketchfab= "https://sketchfab.com/models/422b961ff3d14e7baa7e9077572b2247/embed"

geometry: quads/tris. polycounts for the tree range from 1000 -> 2800 tris.
in scene:
verts 11433;
polys: 8587 (quads: 7259 / triangles: 1328);
tris: 15858.

file formats:
- 3ds max 2015 v-ray;
- 3ds max 2012 standard materials;
- obj (multi format);
- 3ds (multi format);
- fbx (multi format);
- cinema 4d r16;
- unity 5.6.1 unitypackage* (characteristics for unitypackage are slightly different, because the unity does not contain 2-sided material. i used two planes, one of which inverted the normals. textures of branches are reduced for productivity).

features:
- every model consists of four separate objects: trunk, brunches, foliage_mat_1, foliage_mat_2;
- models is fully textured with all materials applied;
- objects are grouped and named according to their real purpose, allowing the model to be rigged and animated easily;
- no extra plugins are needed for this model;
- lights and cameras are not included in the scenes.

all textures are jpeg format with the following resolutions: 2048*2048;
textures :
trunk, branches: diffuse, specular, normal;
foliage_1, foliage_2: diffuse, specular, normal , opacity;

rendering: marmoset toolbag 3, unity screenshots.
