Hello
Same here for python. Even check by AddPortIsOK(), says True, not adding

I also test c++ code, it adds to object operator(like topic master wants) but does not to nodemaster and no connect

{
    BaseDocument *doc = GetActiveDocument();

    BaseObject *obj = (BaseObject *) doc->GetActiveObject();
    if(!obj) return FALSE;

    XPressoTag *xTag = (XPressoTag*)obj->GetTag(Texpresso, 0);
    if(!xTag) return FALSE;

    GvNodeMaster *nm = xTag->GetNodeMaster(); 

    GvNode *n1 = nm->GetRoot();
    GvPort *p1;
    if (n1->AddPortIsOK(GV_PORT_OUTPUT,40000002))
    {
	    p1 = n1->AddPort(GV_PORT_OUTPUT, 40000002, GV_PORT_FLAG_IS_VISIBLE, TRUE);
	    print("True"); 
    }
    else
    {
	    print("False"); 
    }
      
    GvPort *p3 = n1->AddPort(GV_PORT_OUTPUT, 536870935, GV_PORT_FLAG_IS_VISIBLE, TRUE);
    
    GvNode *n2 = nm->CreateNode(nm->GetRoot(), ID_OPERATOR_OBJECT, NULL, 0, 0);
    GvPort *p2 = n2->AddPort(GV_PORT_OUTPUT, 40000002, GV_PORT_FLAG_IS_VISIBLE, TRUE);

    if (p1 && p2)
    {
        GvNode *n1u = NULL;
        GvNode *n2u = NULL;
        GvPort *p1u = NULL;
        GvPort *p2u = NULL;
        if (nm->IsConnectionValid(n1, p1, n2, p2, n1u, p1u, n2u, p2u))
        {
          n2->AddConnection(n1, p1, n2, p2);
        }
     }
    n1->Message(MSG_UPDATE);
    n2->Message(MSG_UPDATE);
    nm->Message(MSG_UPDATE);

    EventAdd();
}

@m_adam said in [python] SetFont not working:

In which version are you? The code I posted is working nicely in R20.059.

20.059. Before i tried any methods, that's my fail. Not work for me. From new start of c4d. - it works
