The Khronos Group is working on a new open standard tentatively called the glTF External Reference Format (or glTFx for short), which will allow users to add multiple glTF assets to a single scene. This used to be called the "glTF Experience Format (glXF)," and the final name is still being finalized. This will enable new capabilities that are not possible by using glTF itself to contain other glTF assets, which includes is level-of-detail (LoD) management, asset-based lighting Management, and billboarding. The Khronos Group continues to translate the core functionality of game engines into various open standards, and are also working towards finalizing glTF extensions for interactivity as well as for physics.

I did a deep dive with Khronos 3D Formats Working Group Chairman Alexey Medvedev (AR Tech Lead at Meta/Facebook), and 3D Formats Working Group Vice Chairman Dan Frith (Chief Creative Officer at London Dynamics) to unpack all of the latest news about glTF and glTF External Reference Format.
