Are there any plans for adding importer/exporter for [Universal Scene Description (USD)](https://graphics.pixar.com/usd/docs/index.html) format? It looks like a very nice and widely supported file format for data exchange, which is much friendlier than low-level glTF file format and supports many useful concepts, such as well-defined storage of custom metadata, layers, hierarchies, etc.

I don’t know of any plans but at first blush it sounds like a decent idea. It all depends on how expressive and useful the format is. The earlier VRML classes were rarely used…

I would be keen for this feature - it would help me in some work I do with the Nvidia Omniverse!

All the best,

Oliver

[NVidia has a ParaView plugin](https://docs.omniverse.nvidia.com/con_connect/con_connect/paraview.html) doing that but with Omniverse integration. Extracting the writer/exporter would be nice indeed.
