    My first post here ;)

    Problem: when I use Python to set up a userdata output port on an xpresso node on the active object, it turns yellow and won't work, yet when I drag the same object into the xpresso tag setup and set the output port to the userdata it looks and works as expected. Seems to be just the userdata output port that is the problem, as other output ports work fine when set using Python.

    I suspect that I am not making an internal connection somewhere--or that it possibly is broken.

    Any ideas?

    Here's the Python code I am using:

    import c4d

    def main() :
        ActObj = doc.GetActiveObject()

    Make the user data boole button on active object

    bc = c4d.GetCustomDatatypeDefault(c4d.DTYPE_BOOL) #create default container
        bc[c4d.DESC_NAME] = "Pucker"                        #rename the entry

    Pucker = ActObj.AddUserData(bc)           #add userdata  and set to container
        ActObj[Pucker] = False                          #assign a value

    #c4d.EventAdd()                                   #update

    Create the xPresso tag on the active object

    xtag = c4d.BaseTag(c4d.Texpresso)
        if ActObj is not None: #check if there is no object
            ActObj.InsertTag(xtag)

    tag = op.GetFirstTag() # returns the first tag of the object
        nodemaster = tag.GetNodeMaster()

    Generate node with port

    nodeObjOut = nodemaster.CreateNode(nodemaster.GetRoot(), c4d.ID_OPERATOR_OBJECT, insert=None, x=250, y=200)

    nodeObjOut.AddPort(c4d.GV_PORT_OUTPUT, [c4d.ID_USERDATA, 1])

    nodemaster.Message(c4d.MSG_UPDATE) #send update to nodemaster
        c4d.EventAdd() #set an event to c4d core to update (never use in an expression)

    main()

    Hi ernia,

    for user data you need to specify some additional IDs. I also recommend to inform the node about the new port by setting "message=True".

    USERDATA_NUMERO = 1 #change this
nodeObjOut.AddPort(c4d.GV_PORT_OUTPUT, c4d.DescID(c4d.DescLevel(c4d.ID_USERDATA, c4d.DTYPE_SUBCONTAINER, 0), c4d.DescLevel(USERDATA_NUMERO)), message=True)

    For custom datatypes like gradient, splinedata, ... you should define their type as well ( c4d.DescLevel(USERDATA_NUMERO, c4d.DTYPE_GRADIENT, 0) )

    Cheers, Sebastian

    Thanks Sebastian.
    Not sure what it all means but it's working fine now.

    Wow, I've been looking for AddPort for Userdata for ages!

    Sebastian, is it documented somewhere? Is there a way I could get there by myself?
