Hi Robert, The OSG automatically reference counts Nodes and other objects in the scene graph. If you want to remove Nodes or other objects from the scene graph you need to call the appropriate methods to removing them. If you want to remove a child from a group then you simply call group->removeChild(child);
I can't see how calling group->removeChild(child) is complicated, it's about as straight forward as one can get if you want to remove a referenced from one object from another. It really isn't a case of doing group->removeChild(child) as well, it's usually the one thing you need to do. If you have other ref_ptr<> references to the child then once these ref_ptr<>'s go out of scope then what they are pointing to will be automatically unrefenced, and if this is the less refernece to it, it will be automatically deleted for you. It's really hard to know what you are struggling with in your own application usage, but it rather sounds like you are over managing things. Robert.
