Hi Martin, The OSG supports subgraphs having multiple parents and hence multiple world coordinates. Whether you would want to use this facility will depend upon the what you are trying to do - typically you'd use this facility to place multiple subgraphs like cars wheels onto a car, or a trees into a forest. To find out the world coords on any subgraph simple do node->getWorldMatrices(), this will give you a list of the world matrices that it finds when ascending all the possible parental paths.
