Most of the examples pre-date the change to allow Drawables to be added directly to the scene graph. Since there are so many examples it's a bit of task to rewrite them all. New examples won't use Geode. > > > > However, as I've only seen a tiny snippet of your code and explanation > > I can't really say where you've understanding of how best to implement > > what you need has gone off in the weeds. > > > This is a very real possibility.

All classes of osg::Object have support for a object->setValue("name", valu) and bool result = object->getValue("name", value); This is what I'd use for debug/supporting data. Nest a Geode within a Geode is just plan bad practice. It's misusing something that was never intended to be used in the way you were using it. There are *no* OSG examples that do what you were doing, you've invented a new way to misuse the OSG. > > Another general comment is that it's not recommend practice to go > > adding objects to the scene graph from within a NodeVisitor. > > Understood.

I don't know enough about what you are doing to pinpoint exactly what you should use for the task. At this point you've provided a "solution" that you want to debug, what I'm saying is the "solution" has a number of odd things about it is likely completely the wrong way to tackle that task. The best way to get feedback on how to do things is provide a clear high level explanation of what functionality you'd like to implement then others can suggest the way they would tackle it.
