I write these for a view3d ...... my model is tested online on https://gltf-viewer.donmccurdy.com/ ...and have these test report:

UNUSED_OBJECT	This object may be unused.	/meshes/0/primitives/0/attributes/TEXCOORD_0
UNUSED_OBJECT	This object may be unused.	/meshes/0/primitives/1/attributes/TEXCOORD_0

UNUSED_OBJECT	This object may be unused.	/meshes/2/primitives/2/attributes/TEXCOORD_0
UNUSED_OBJECT	This object may be unused.	/meshes/3/primitives/0/attributes/TEXCOORD_0

code for print model on a view3d ( these is code for model 6... but other is equal) ....

                                Model {
                                    id: robotMod_6
                                    source: "qrc:/models/u0_6.glb"
                                    pivot: Qt.vector3d(0, 35, 0)
                                    eulerRotation.y: useBusData ? busValues[5] : sliderValues[5] || 0
                                    Component.onCompleted: console.log("Load model: 6", robotMod_6.status)
                                }

error obtained ....
