The
gltfspec allows to have a.glbfile without a binary buffer so that all buffers are either encoded asbase-64or pointing to an external resource. https://github.com/KhronosGroup/glTF/tree/master/specification/2.0#chunks.The current implementation does not honor this use case and always skips the first buffer, even if it is not a binary buffer.
With this change the decoder will check if the first buffer is an binary buffer, and only if it is it will add the binary chunk to the file.
