All models included contain only tris and quads, with good clean topology. All models included are 20cm (7.87 inches) in height. For all meshes topology is set up so that model can be used without subdividing/smoothing as a background element. In case any model is to be used as the center piece of your render it can be subdivided/smoothed without any changes in its silhouette.
Polygon count varies between 11,872 to 92,286. Polygon count shown in the 3D model specification section is the sum of all 10 models.
A 3 page .PDF file is included with a preview of 4 models per page so that you can easily decide which model best suits your scene.
Please feel free to check out my profile as all models included in this collection are also available for individual purchase. Also there you can find more details about individual polycount and topology as more wireframes are available.
