The developer walks through a new PR that adds a GltfExtensionHandler trait to Bevy, enabling third-party crates to process custom glTF extensions rather than being limited to glTF extras. The stream covers the conceptual difference between glTF extras (application-specific key-value data) and glTF extensions (more generic, can include global root data, buffer data, or no data at all). Practical demos include building an animation graph via a glTF extension and converting 3D meshes to 2D for use in a 2D game. The developer also works on integrating this into the Skein (Scheme) Blender-to-Bevy workflow tool, aiming to migrate component data export from extras to extensions for better interoperability. ## Full article daily.dev links to this article rather than hosting it.
