How to convert DirectX (.x) to Unreal Engine?

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.

DirectX

.x files are the native 3D file format of the legacy Microsoft DirectX v2/v3 API and 3D toolkit. They were generally associated with 3D gaming whereby low polygon meshes with skinning (deformation) and "animation sets/clips" were the required norm. At the time of its introduction in 1995 there really wasn't any other similar 3D file formats which supported these capabilities in one, well defined and easily accessible format. Direct3D shipped for the first time in the DirectX 2.0 SDK in June 1996

Historically, the DirectX technology was developed a company called Rendermorphics of the UK which Microsoft purchased in February 1995. As little known history, 3 companies in the UK developed advanced realtime rendering toolkits prior to 1995: Argonaut Software (BRender), Criterion Software (RenderWare) and Rendermorphics (Reality Lab). Microsoft was to license the Argonaut 3D toolkit but opted to purchase the entire Rendermorphics company instead, at the last moment. As these various toolkits often sold for $50k at that time, the other two competitors eventually went out of business once Microsoft started giving DirectX away for free.

Okino knows of the .x file format well as it was the first company to properly and fully implement a DirectX importer and exporter, including full support for skinning and animation at a time when no other software provided such conversion support.

The DirectX file format had a long life until some people inside and outside of Microsoft started to push the FBX file format instead.

Unreal Engine

Unreal Engine (UE) is a popular 3D computer graphics game engine developed by Epic Games. It is available as open source and is free to use until a title earns a specific dollar value in revenue.

Okino has long supported Unreal Engine as the first and main 3D conversion program to do so. In the simplest terms possible, conversion from Okino software to Unreal Engine 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 Unreal users has been for the conversion of all major MCAD data formats into a highly optimized and efficient form for realtime usage within the Unreal Engine. We also invented the processes for animation + skinning/bones cross conversion so that is well supported for Unreal Engine. 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.
