Yeah, don't do that. > Don't know why,need help! You're holding a raw pointer to a reference counted object. The reference count drops to zero when you call 'setUpdateCallback(NULL)' or 'removeUpdateCallback()' which deletes the object. When you then call 'delete nc' you try to delete an already deleted object. Use osg::ref_ptr. /ulrich _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
