HI, I want to make a copy of an existing node and all it's children, and then find all the geometry and make it transparent.
I do something like osg::ref_ptr<osg::Node> copyA = new osg::Node(*A, osg::CopyOp::DEEP_COPY_ALL); where A is the original Node tree. If I try to use the findNodeVisitor: findNodeVisitor nv(FINDNODETYPE_NODETYPE|FINDNODETYPE_FINDALL, "Geode"); copyA->accept(nv); std::vector<osg::Node*> nodeList = nv.getNodeList(); int length = nodeList.size(); then length is 0. If I do the same with the original node: findNodeVisitor nv(FINDNODETYPE_NODETYPE|FINDNODETYPE_FINDALL, "Geode"); A->accept(nv); std::vector<osg::Node*> nodeList = nv.getNodeList(); int length = nodeList.size(); then length is 32. Also if I try to cast the copyA to a osg::Group* I get a null pointer: osg::Group* temp = dynamic_cast<osg::Group*>(copyA); temp is a null pointer. So did I miss a step somewhere?
