The Ultimate Guide to Turn FBX Files into SimReady USD Content

This guide is part of the RapidPipeline 3D Formats Knowledge Database.

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.

USD (Universal Scene Description) is the primary format to generate SimReady data, enabling 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 SimReady USD asset.

With RapidPipeline, the process of generating NVIDIA SimReady USD content from FBX files is easy:

1. Download RapidPipeline Twin Studio, or one of the RapidPipeline 3D tool plugins (free trial available). Alternatively, you can also use RapidPipeline directly in the browser.
2. Perform the conversion from FBX to USD. Store or download the resulting USD file, it's ready to use!
3. If you'd like to scale up the process, simply get in touch to acquire a license for the RapidPipeline 3D Processor, running as powerful batch processing tool that turns your entire library of FBX files (or other files) into SimReady USD content.
