How to convert OpenFlight (.flt) to Unity?

PolyTrans|CAD+DCC performs mathematically precise CAD, DCC/Animation, GIS and BIM 3D file conversions into all key downstream 3D packages and file formats. Okino software is used and trusted throughout the world by many tens of thousands of 3D professionals in mission & production critical environments, backed by respectable personal support directly from our core development team.

OpenFlight

OpenFlight is an industry standard realtime 3D scene description format developed, owned and maintained by Presagis, Inc. OpenFlight is the most widely used file format for visual simulation databases and is supported by dozens of vendors of realtime 3D tools. Military visual simulation includes battle simulation, fighter jet flight simulation, tank simulation. Visual simulation also includes geospecific terrain for accurate realtime fly through of regions of the planet.

In visual simulation, OpenFlight is the defacto standard format. OpenFlight is also prevalent in the PC animation and modeling communities for optimizing and tagging 3D data for realtime playback. As application examples, in the visual simulation industry OpenFlight is the format for entire worlds. In the entertainment industry it is widely used for level building in realtime games and in the AES or urban simulation industries it is used to organize and optimize scenes for realtime walkthroughs.

Unity

Unity is a cross-platform game engine developed by Unity Technologies, first announced and released in June 2005. The engine has since been gradually extended to support a variety of desktop, mobile, console and virtual reality platforms. It is particularly popular for iOS and Android mobile game development.

Okino has long supported Unity as the first and main 3D conversion program to do so. In the simplest terms possible, conversion from Okino software to Unity is done via the FBX file format.

For those who may be unaware of Okino software, for over 30+ years we have been the pioneer 3D conversion company that wrote the rule book on how DCC, animation and MCAD data is to be cross-converted between all major 3D programs and file formats. Key uses of our software for Unity users has been for the conversion of all major MCAD data formats into a highly optimized and efficient form for realtime usage within Unity. We also invented the processes for animation + skinning/bones cross conversion so that is well supported for Unity. As a minor point of interest, Okino was also the very first implementor of the FBX file format as of 2002, long before Autodesk bought the bankruptcy assets of Alias Research and provided free access to the FBX SDK; hence, we provide highly reliable and robust FBX v5/v6/v7 support.
