HI Nick, The way the OSG implement node callbacks are as traversal callbacks that are nested within the traverse of the node itself, so it's in effect a traverse children callback. In the case of osgSim::LightPointNode it's implemented as a leaf node so doesn't bother calling NodeVisitor::traverse() to traverse any further so the callbacks aren't called.
The best I workaround I can think of is subclassing from LightPointNode and overriding the LightPointNode::traverse() method to add in a NodeVisitor::traverse() call as well as the LightPointNode::traverse(). Another route might be to add the update callback to the parent. Or perhaps just subclass from LightPointNode and treat this subclass as your update callback etc. Robert.
