A realistically and approximately measured generic building with minor detailed interior included with tree and textures for both tree and building.
The interior is a base idea,like an empty canvas,for those who wish to fill the interior with their own furnitures,rooms and so on.
This model comes with all the textures needed with bump and spec map counterparts for all where needed,alpha map also included for tree leaves.Main textures images are in Hd res 3000x3000,jpg
The materials and shaders are blender cycles internal.
This model is designed with approximate measurements of a large building inside and out.
The polys and vert counts mentioned in the information box on the right is referring to the building alone.
Please note that the unnamed format is in x3d form.
Also note that the images after the wireframed shot are not included they are advertisements of my other works on turbosquid.
