         **Note Remember, the nodes of the ports have to be in the same` GvNodeMaster`, otherwise the connection fails.**
        

        Also i trying to make clone of tag/Nodemaster and do versa - fails

          Hi Ilya,

          I'm afraid, this currently a limitation in Python. As you need to connect two out-ports inside the Xgroup, this does currently not work (same for the input side as well).
          I'm currently checking with development, if there are workarounds.

            Hello Andreas
            Thank you! I will wait.
            I also will test such code with c++ port. Maybe need to port code to CAPI if will be success

                    Hi Ilya,

                    actually I didn't mark this thread as solved, as I had no answer from the devs. Today it was acknowledged as a limitation. It is currently not possible to connect an output of a node to an output of the parent Xgroup in Python (same for input nodes). Unfortunately there seems to be no workaround. Sorry.

                    Regarding your C++ code and the missing connection. I think, you need to call AddConnection() for the other node involved. See this thread.

                      I add tag to name of topic, thinking it was resolved.

                      I don't understand one thing in py-sdk, why need such checking - GvNode.IsGroupNode

                      About c++ snippet, i tried different ways and same result.

                      Also if it will be (x)group why need this https://developers.maxon.net/docs/Cinema4DCPPSDK/html/group___g_v___g_r_o_u_p.html

                        I did it by c++, i don't know what was wrong. After restarting of machine - it worked! (caches or anything else prevent it)

                        i change

                        n2->AddConnection(n1, p1, n2, p2);
                        

                        to

                        n1->AddConnection(n1, p1, n2, p2);
                        

                        i move to c++(maybe S.Rath will bring light to py-code). Solved. Thank you

                          glad it worked in C++.
                          The developer feedback I talked about yesterday came from S. Rath. I'm afraid you will have to wait for a fix in C4D for this to work in Python.

                            R17? or will be sp4 for r16?

                            Anyway, please, close topic. I will port stuff to c++

                                you seem to have found out yourself. I would have left a note here, if the SP fixed this bug. Internally this bug has been addressed, but it was to late to get into the 16.051 update.
