This is a mid to high poly model of a Landing Platform and Lift tower for use in your renders. They come in .obj format with associated .mtl files and can be opened by most 3d software. It has been tested on Cinema 4d, Poser 6 and Daz Studio 2. Other software shouldn’t be a problem , but each one may have a different scaling factor on import, so if you don’t see it in the viewport immediately , try rescaling.
The .mtl files have 50+ different materials for the main areas and equipment, each coloured differently for ease of identification.
