Skyscrapers mini pack contains five different lowpoly buildings with diffuse, normal and specular textures.
Textures are tileable with resolutions: 256x256; 256x512; 512x512
*specular maps in the alpha channel of the Diffuse textures
Please note that I changed the Shadow Distance parameter in the UnityEditor from 40 to 900 because of the building dimensions (1:1 scale).
