Hello
I have xpresso setup:

root - node, which is xgroup and has 2 output ports
new node - node, which has 1 output port
I tried to connect them (one output of root and one output of new node) but there is not success.

I understand that need INPUT + OUTPUT ports, but how can be with 2 outputs by code?
Manually we can make such connection.

Sample code, execute at any c4d object, problem that ports do not connect (24 pos./line) :

import c4d

  print "pass 1"

      print port, port.GetName(xg), port.GetMainID()  
        
  bbox = nm.CreateNode(nm.GetRoot(),c4d.ID_OPERATOR_BOX,None, 0, 0)  
  nm.InsertFirst(xg, bbox)  
    
  if not xg.GetOutPort(0) :  
      vecoutp = xg.AddPort(c4d.GV_PORT_OUTPUT, 536870935)         
        
  c = vecoutp.Connect(bbox.GetOutPort(0)) # <<<<< not connect  
  print vecoutp, vecoutp.GetName(xg), vecoutp.GetMainID()  
  print bbox.GetOutPort(0), bbox.GetOutPort(0).GetName(bbox), bbox.GetOutPort(0).GetMainID()  
  print c

      port = xg.GetOutPort(i)

Has python for c4d such limit now? Or possible to do another way?!

Nodes are laying in same nodemaster

`

GvPort.Connect`( _port_ )
 **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

There is interesting, it marks ports(arrows) but not show connections

Hi
A few things are not as expected, so i remove flag solved at topic.

Andreas, any info about to break limit?

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

Andreas, you are right!!!
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

Hi Ilya,

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++

Hi Ilya,

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.
