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.

About USD and SimReady Content

Omniverse supports various file formats. However, the native file format is USD, which is the officially recommended file format for best performance.

USD (Universal Scene Description) is the primary format for Omniverse SimReady data, it enables 3D assets to be used in simulation environments such as NVIDIA Omniverse, PhysX, and more. For this to work properly, USD assets must adhere to the USD standard, and ideally bring metadata that helps to inform downstream simulation use cases about various simulation-relevant properties of the 3D asset.

There are various ways to generate USD files, but especially when starting from non-simulation formats like FBX, it is not easy to perform a good conversion. Additional required steps might include material assignment (in case realistic materials are desired) and related steps like UV generation, but also metadata transfer from the original file to the final Omniverse SimReady USD asset.
