FBX files are an open 3D file format developed by Autodesk for use with their Maya and 3Ds Max applications. An FBX file may contain any number of 3D objects, their associated geometry, materials, textures, animations, and more, all within a single convenient package.
The content of an FBX file is a mix of binary and ASCII text, producing a format that is both human-readable and compact. Due to their compact size, ease of use, and widespread support, FBX files are a popular choice for creating 3D animations and are also a staple in the videogame development scene.
The development of the FBX format continues to this day, with new features being included in each release. Along with being used within Autodesk's own editing solutions, FBX files can also be opened and edited in other popular 3D modeling applications, such as Blender.
FBX Converter Capabilities
When converting 3D model or mesh files using our FBX converter, we will attempt to convert color materials into a suitable format for use in the converted file.

The X file format is the legacy format used by the Microsoft Direct X suite of components and tools. Specifically, X files are used to store hierarchical 3D objects along with their associated material, texture, lighting, and animation data.
The 3D data is stored as plain text in the X file, allowing for manual editing within a simple text editor. 3D mesh surfaces are defined using a series of vertex coordinates and joined with lists of face indices. Along with these are optional normal and texture coordinates for textured surfaces; the textures themselves are often stored as external files using the DDS file format.
As mentioned previously, the X format is a legacy format and is no longer widely supported, with developers preferring to use modern formats such as FBX instead. That said, some 3D modeling applications still support importing and exporting to the X format.
