It's a set formed by three books of c4d native extension file. Good choose for low geometry mesh with good detail. Books' titles and authors don't exist, they're exclusive textures made with bodypaint at 800x800. Each book contains 1158 polygons and does not include triangles. Zip includes books 3d model with textures only, not floor. Books size is about A3/A4/A5. Real world scale. Zip includes 3ds and obj with no textures/shaders applied. Books order and position are the same of OpenGL preview.
