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()-ScottA

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.

Yes! This works! I have a question, though. The code below will reset everything within the group without hardcoding individual userdatas. I would like to avoid that as there are so many. Can this be done?

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.-Niklas

It's not your place to give your almighty approval on how to answer someone's question.I've managed hundreds of people and several business for over three decades.

Oh hell no.
You weren't even an idea when I was managing people for a living.

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.
