      Thanks for taking a look, Andreas. Hopefully one of the Python gurus can point me in the right direction. I have over 100 of these and user data approaching 3K.

        I have made a quick reply into c4dcafee.
        As said try to avoid same question on multiple forum. I guess this one will be better for continue this discussion since support team can give their advices too 😉

          Is there a way for getting the bc of individual user data without hte need to loop?

          Like something liek that but without the loop wich is really not efficiency at all.

          import c4d
            
          def main() :
            if op is None: return
            
            desc_id, bc = get_bc(4)
            op[desc_id] = bc[c4d.DESC_DEFAULT]
            c4d.EventAdd()
            
          def get_bc(my_id) :
              for id, bc in op.GetUserDataContainer() :
                  if id[-1].id == my_id:
                      return id, bc
            
          if __name__=='__main__':
            main()

              GetUserDataContainer() over and over again is pretty slow. Call it once and reuse the result.

              ud = op.GetUserDataContainer()
              desc_id, bc = get_bc(ud, 4)
              

              To optimize the loop to find the matching entry, you can build a dictionary first.

              ud = {}
              for id, bc in op.GetUserDataContainer() :
                ud[id[-1].id] = (id, bc)
                
              desc_id, bc = ud[4]

                Yes it's what I did but I fel not optimized.
                I should not post on c4dcafe but only here.
                So to the op I will stop the answerd on the c4d cafee 😉

                  Yes.
                  You can get the data for a specific UD item by either it's ID#. Or by it's position within the UD stack.
                  Here's an example of getting a specific UD item by it's ID# in the UD manager:

                  import c4d  
                  def main() :  
                      
                    if op is None: return  
                      
                    index = 1  #<---Change the target UD item as desired  
                      
                    ud = op.GetUserDataContainer()  
                    item = ud[index-1]    
                    bc = item[1]  
                    name = bc.GetString(c4d.DESC_NAME)   
                    udType = bc.GetLong(c4d.DESC_CUSTOMGUI)   
                    units = bc.GetLong(c4d.DESC_UNIT)   
                      
                    #If the UD item is not a Group...Get it's value  
                    if udType != 0:   
                      item_value = op[c4d.ID_USERDATA, index]  
                      print item_value  
                    
                    c4d.EventAdd()  
                    
                  if __name__=='__main__':  
                    main()

                    EDIT: Hooww didn't work in the op exemple since the user id stack is not build from scratch and got some missing id 😕 So I guess my previous method was correct.

                      Tested in the scene file and the code above does not work. The code previous to that will throw the reset switch but none of the user data is reset to default.

                        @ScottA that's not always going to work since the IDs are not garuanteed to be continous (delete a userdata) or in orde (re-order parameters). Hence my proposal with the dictionary.

                              for id, bc in obj.GetUserDataContainer() :

                                There are 16 user data variables for each of 10 presets and there are 10 sets of presets so I am looking at hardcoding 1600 userdatas. I would like to avoid that if possible and just use the Group user data id so that everything within the group is reset. Also, this way if I add to the group, I don't have to worry about the code missing that parameter because I didn't reference its specific ID.

                                  You posted your answer without any information on potential
                                  issues or limitations, thus I must assume that you either do not
                                  know them or forgot to include them in your answer.

                                  Either way, I feel obliged to point out that your answer only
                                  works in a special case, namely when you create the userdata
                                  sequentially and do not modify it afterwards.

                                  If you answer a question without the intend of someone using
                                  the information from your answer, why answer it at all.

                                        Is there a way instead of using the tuple to just use the group user ID and some code that refers to what's under it instead of hardcoding what's under it? That would solve the problem.
