The triangle counts for each model range from about 100 --> 1400
Many of the models share textures so as to optimize batching performance.

The higher poly models come with a set of LODs that reduce triangle count by about 50% at each LOD stage.

Most materials are set up with Unity 5 standard specular shader and come with a diffuse / normal / specular texture.
Larger objects use 1024x1024 textures while some of the smaller ones use 512x512 textures.
