@m_magalhaes Manuel you hero! That was it! DeformedPolygonCacheIterator was the key! Thank you so much!

@ferdinand I will handle it. Thanks for your help! Cheers~

@m_adam Thanks Maxime, I'll check that out. The customer was using R23.110

@m_adam That clears it up, thanks Maxime!

@m_magalhaes Thanks Manuel!

@m_magalhaes yes thanks that was my idea, too , I created a temporary object, in my case a spline with 0 points and 0 segments and simply exchanged it, thanks.....

thanks.

@m_adam Thanks

I came up with this solution which is working fine. Thanks for your help. std::string getDropDownName(Description* const description, Int32 group_id, Int32 SelectedItem) { const DescID* singleid = description->GetSingleDescID(); const DescID cid = DescLevel(group_id, DTYPE_LONG, 0); std::string selected_name = ""; if (!singleid || cid.IsPartOf(*singleid, nullptr)) { AutoAlloc<AtomArray> arr; BaseContainer* selectionParameter = description->GetParameterI(DescLevel(group_id, DTYPE_LONG, 0), arr); if (selectionParameter != nullptr) { BaseContainer* items = selectionParameter->GetContainerInstance(DESC_CYCLE); if (items != nullptr) { selected_name = items->GetData(SelectedItem).GetString().GetCStringCopy(); } } } return selected_name; }

@m_magalhaes This worked great, thank you.

Hi Ferdinand, No worries! Thanks for the reply, it was very helpful as a starting point. I ended up using the c4d.GetWorldContainerInstance() and then c4d.WPREF_AUTOSAVE_DEST_PATH to get the custom filepath and then just a SaveDocument with the AUTOSAVE flag seems to be doing the trick. thanks again!

@m_adam Thanks a lot for the benchmarking Maxime. I was planning to go for the string method, I'm surprised it's not faster. I wasn't planning to use this for a plugin, not to mention C++, but it's good information to have.
