glTF Reference Format (glTFX) is the specification for a new file type in the glTF ecosystem for efficient composition of multiple glTF assets.
This section explainers many aspects of the specification. It was developed prior to written the glTFX Specification documents and frequently presents multiple solutions that the specification editor team may choose to restrict.
