The author does not give his consent to the use of this material in his models uploaded to the drains, including 3ddd / 3dsky. There is no fog geometry in the archive: You acquire the procedural fog material. In the files .max is a simple Box, with a material superimposed on it, as well as a surface for CoronaDistance work. It is recommended to install the Corona Render version at least 1.5, since the Glossiness of the materials is adjusted with PBR in mind. Creative success!
