The UpdateVisitor by default traverses all children, but you can change it to traverse just the active children via: viewer.getUpdateVisitor()->setTraversalMode(osg::NodeVisitor::TRAVERSE_ACTIVE_CHILDREN); There is however a problem in that LOD's activity is selected during the cull traversal... the update visitor can only assume the highest level of detail children. > 2. How can I check in callback if node is active or not? A cull callback on the child will tell you whether that child is active or not.
