The format was later renamed to OpenFlight to denote its nonproprietary image generation (IG) usage.
[citation needed] The early advantage OpenFlight held over many 3d geometry model file formats (.obj, .dxf, .3ds) was its specific real-time 3d graphics industry design.
OpenFlight models can have several associated files in different formats, that define elements such as material characteristics or shaders.
Carbon Graphics' Geo STUDIO is also very active in developing its OpenFlight version and feature support (currently standing at 16.3).
Because the OpenFlight file format allows for vendor specific data field additions, some modeling and simulation tools might not fully support vendor specific additions to the file format.
