GLTF Save support material names

Aspose.3D Product Family

Hello,

When I export gltf I’d like to preserve material names but they seem to disappear:

See the spec: https://github.com/KhronosGroup/glTF/blob/master/specification/2.0/README.md#metallic-roughness-material

Could material name be added, or is there an option I am missing?

See following unit test:

    [Test]
    public void Gltf_supports_material_names()
    {
        Scene scene = new Scene();
        
        scene.RootNode.CreateChildNode("SomeCube", new Box(10,10,10).ToMesh(), new PbrMaterial(Color.Red)
        {
            Name = "RedMaterial"
        });

        string gltfContent;
        
        using (var ms = new MemoryStream())
        {
            scene.Save(ms, new GltfSaveOptions(FileFormat.GLTF2)
            {
                PrettyPrint = true,
                SaveExtras = true,
            });

            ms.Seek(0, SeekOrigin.Begin);


            using (var sr = new StreamReader(ms))
                gltfContent = sr.ReadToEnd();
        }
        
        Assert.True(gltfContent.Contains("RedMaterial"));
    }

This problem seems to continue to exist. When I export the gltf file, the filename of the texture of each material is lost. The complete filename name is given when exporting, but it is null when I import it again.
