Hi Dat, Finding specific children in a loaded scene graph is very common thing to do, and one usually just write a custom NodeVisitor to do it. Have a look at the osgplanets and osgsimiulation examples for an example of FindNamedNodeVisitor - use this as a template and modify to specialize it to your needs.
