Hi Suikender, It's meant that one would subclass from osg::Object rather than ValueObject for complex user types. The ValueObject type is meant just for simple values not composite/array values. Extended the OSG serializer classes is quite straight forward so I wouldn't worry about this aspect - once you wrapped a couple of classes it becomes pretty natural. The osguserdata example illustrates this in action.
