Why not just used node masks ? This is the typical way to approach this problem

Unfortunately it didn't work as aspected, and I don't know where I'm wrong. I modified the osgpick example (attached) to pick, for instance, only the rectangles in the HUD. What I do is: - store the root of the HUD in a pHudRootNode - pick with the funtion viewer->computeIntersections(ea.getX(), ea.getY(), pHudRootNode->getParentalNodePaths()[0], intersections) but I don't get any result. I've also tried to limit the nodepath to the view's SceneData, like this: pHudRootNode->getParentalNodePaths(viewer->getSceneData())[0] but it doesn't work either. Where am I wrong? Thank you!
