What is the FBX format, and what is it used for?

FBX (Filmbox Format) is a proprietary format by Autodesk that became popular as exchange format across common 3D graphics applications. Despite being non-standardized, authoring and runtime applications have developed sophisticated support of advanced FBX features such as animation data and PBR materials, yet all in their own flavor and therefore not always compatible across applications. It is a file format mostly used for interactive 3D & rendering applications.

0 - The FBX SDK includes dedicated NurbsSurface and NurbsCurve node types. However, support varies by application — some tools (e.g. Blender) convert NURBS to meshes on export.
1 - FBX binary format uses zlib/deflate compression for geometry array data internally. It does not support dedicated geometry compression schemes like Draco.
2 - Multiple PBR models are supported as there is no standard for materials in FBX.
3 - Compatibility of all properties strongly depend on particular compatibility of the tools that export / import the DCC file, as there is no clear standard for this format.
4 - FBX does not enforce a specific image format or GPU-level texture compression. Embedded textures can use compressed formats like JPEG, but formats such as BCn/DXT are not natively supported.

Converting and Optimizing FBX Files

There are various ways to convert between FBX files and other 3D formats. With RapidPipeline, you can easily convert and and optimize FBX files, at scale. It supports FBX, as well as many other file formats (examples: 3dsMax, 3MF, ACIS, AutoCAD, CATIA, COLLADA, Creo, DGN, glTF, I-deas, IFC, IGES, Inventor, JT, Navisworks, OBJ, Parasolid, PLY, PRC/U3D, Revit, Rhino 3DM, Solid Edge, SolidWorks, STEP, STEP Enhanced, STL, USD, USDZ, VDA-FS, VRM, VRML), at high quality.

Due to the potential limitations aforementioned on the table above, in principle, this format cannot always perfectly convert 3D data between FBX and other formats. In the following, you can find format conversion guides between FBX and the most important other formats, along with a rough score for compatibility of this workflow:

What's the best way to get FBX files into my 3D applications?

Doing 3D conversion right, especially at scale, can be tricky, as 3D data is in general a rather complex (yet very powerful!) medium. This also applies to FBX files - the conversion guide above gives a rough idea. Once you know what you would like to do, tools like RapidPipeline can help you perform the necessary steps, and to automate the process.

However, especially when introducing pipelines and workflows at scale in an enterprise context, it is usually good to rely on dedicated expertise, making sure you do not introduce any steps into your 3D workflow that are detrimental to the final output's quality, or that take your team too much time (and money).

If you're interested to hire dedicated expertise from the best in the field to help your company reach your goals fast and reliably, please do not hestitate to contact DGG. Being the creators of RapidPipeline, and ambassadors for open 3D standards for more than a decade, we have been building some of the world's most advanced 3D pipelines, having processed many millions of 3D assets.

Therefore, our expertise will help you to reach your goals faster, at scale, and with the least possible friction, since we are focused on maximum interoperability.
