hello

// Here we export Viewport3D:
assimpWpfExporter.AddViewport3D(viewport3D);

AssimpWpfExporter.ExportViewport3D(viewport3D, "D:\\test1.glb", exportFormatId);
bool isExported;

try
{
isExported = assimpWpfExporter.Export(fileName, exportFormatId);

// To export to an in-memory object use the ExportToDataBlob that returns a ExportDataBlob with byte array
//var dataBlob = assimpWpfExporter.ExportToDataBlob(exportFormatId);

//if (!isExported)
// MessageBox.Show("Not exported");
}
catch (Exception ex)
{
//MessageBox.Show("Error exporting:\r\n" + ex.Message);
isExported = false;
}

return isExported;

When you run the code above, a test.glb file is created, but when you open it in the viewer, it says it is an incorrect file.
I did the same as the example and it worked fine.
I would like to know where the problem is.

thank you
