A set of hangers.
The main scene has a set of 8 hangers rendered on a white background with a skylight lighting it, with mental ray photographic exposure control switched on and final gather also switched on.
There's also a separate file containing one hanger, ungrouped, linked to the hook of the hanger. This scene has no lights in it, or exposure settings.
This single hanger format is used for the different format version files of this set, with mesh smoothing switched off, for better compatiblity.
