How to create morphing animation?

[Oleg H.]

Hi. I am trying to create morphing animation using this tutorial. I create a test model in blender 2.93.3 with a shape key
Then save it to gltf (export settings on screen in gltf file animation work.).

And balsam to extract the mesh. After that I open Qt Creator 6.1.2 example "Qt Quick 3D - Morphing Example" and change the path to my mesh

//! [morphtargets]
        MorphTarget {
            id: morphtarget0
            weight: 1
            attributes: MorphTarget.Position | MorphTarget.Normal
        }
//! [morphtargets]

//! [model]
        Model {
            source: "file:/home/work/3D/Othets/meshes/cube.mesh"
            morphTargets: [
                morphtarget0
            ]

After which I launch the project but the animation does not work.

What is the problem?
