It is not possible to insert nodes above the current node because you invalidate the iterators that are processing the lists of node children. To do what you are attempting, you could push the nodes onto a list and then modify the scenegraph after the traversal is finished. -- Bryan Thrall FlightSafety International [email protected] _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
