HI Mark, What do you mean by a child being active? The OSG's concept of a child being active related to which of the children of switch or LOD is selected for each frame.
FYI, the update traversal has a lazy traversal scheme that only traverses a subgraph if it contains update callbacks or the node signal to their parents that they need to be visited by the update traversal. This lazy traversal scheme avoid traversing of the scene graph when updating isn't required so provided significant performance gain over a traversal that visits all children regardless of whether they need it or not. The event traversal has a similar mechanism. Robert.
