@m_adam Hi, and thanks for your feedback and suggestions. The Take System sounds like requiring too much user interaction after the import, and I think we won't therefore consider it/ The motion system and "global" Python Tag seem like coherent alternatives to loading every animation one after the other. Now, the last step is to choose one of those systems... I think we'll first implement the back to back loading of animations as suggested by @kbar, as this seems like the most lightweight and straightforward solution for a quick iteration. Cheers, Loïc.

@m_adam said in Reverse iterators, how to use them?: Hi @C4DS Here the message from the development team which confirms what I said to you previously. Hi Maxime, I didn't doubt what you said earlier. I only wanted to point out that it wasn't clear from reading the documentation which collection could be used with reverse iterators. It's nice mentioning in the documentation about RBegin/REnd, Range based loops, etc ... but not everyone looks into the collection implementation to see which types do have RBegin/REnd or are range based, ... HashMap doesn’t support -- so you can’t use a reverse iterator for that. It wouldn’t make sense anyway because HashMap iteration is unordered. Having used std::map some might expect HashMap to be ordered, but it isn't mentioned anywhere it isn't. But the point has been made, and it is now clear how to use reverse iterator. Topic well be closed as "solved".

@s_bach Okay I will give it a try , and I will do a open source example project for anyone, who would love to do this with python only for Cinema 4D. lol I been making different types c4d python plugins for 3 years now, from 2015 for my studio I work for and I love making c4d plugins. But this will be my first time using GeUserArea Class to the fullest lol.

hello, To keep you inform, I'm asking the devs and this is taking more time than expected. Sorry for the delay. Cheers, Manuel

Thanks for the update Frank. Looking at your "resolutions" I think that the actions you took were responsible, in the first case, to clean the existing derived data for the R20 project, whilst in the second, to refresh the DerivedData subfolder where the newly re-created R21 project was supposed to store intermediate files. Please keep us updated and for the mean time I'm going to set this thread as solved. Cheers

Hello Sebastian, I now understand what the difference is, thank you very much! With the customdata_customgui example file I actually made both a GUI and a custom DataType. So I only needed to change my resource file and modifiy my data code a bit! Best Regards, Florian

@m_magalhaes Hello, thank you very much for your inspiration. You've been very helpful. There is no need to overwrite TranslateDescID(), only two macros HandleDescGetVector and HandleDescSetVector can realize my idea. Thanks again! Cheers, Sean

Hey Guys! I think I figured it out! Will resoond if there's any questions! Cheers! MattG

Hello Maxime, thanks for that detailed answer. Much appreciated. I see, drawing slows down things massively. (3minutes vs. a few seconds) Bad luck for me then. :) But it still helped me though, I'm now going for another approach. (The GUI part was just for convenience, so everything is fine) Thank you and cheers, Robert

Thanks Maxime! In the mean time I will cycle through takes, AOVs and Frames manually to get the paths.

@m_adam Thanks! Thats a perfect explanation that solves many of my issues - even in some of my other Plugins. I am sorry, I did in fact refer to c4d freezing when I said crashing. Sorry for the confusion.

@m_adam , AddEventNotification was exactly what I needed. I created a notification to NOTIFY_EVENT_UNDO, and then add my object to it. Now if I delete anything from my object after a polygon is deleted, it will be restored with Undo. Thanks! case MSG_NOTIFY_EVENT: { CHECK_BREAK( data != nullptr ); const auto eventData = static_cast<NotifyEventData*>( data ); if( eventData->eventid == NOTIFY_EVENT_UNDO ) { NotifyEventMsg* notifyMessage = static_cast<NotifyEventMsg*>( eventData->event_data ); CHECK_BREAK( notifyMessage != nullptr ); if( notifyMessage->msg_id == Int32( UNDOTYPE_DELETE ) ) { eventData->doc->AddUndo( UNDOTYPE_CHANGE, Get() ); } } break; }

Thanks for the response. I changed my code to match the example you gave and it seems like that fixes the immediate problem I was running into. It will take some tests to verify if this covers all of the circumstances that I need it to. I appreciate the help. John Thomas

Thanks! I'll try that.

Hello Maxime, thanks for your answer! Its too bad that I can't do it without some hacky way, but thanks for your code snipped and example. I'll mark this thread as solved, so thanks! Best Regards, Florian

hello, this look awkward. I've opened a bug entry and foward this to the devs. It look like with the c++ API, the object is on a uninitialized state. Just this simple code will make your cinema4D hang (it enter an infinite loop). if (!doc->DoUndo()) { ApplicationOutput("Failed to DoUndo()"); return maxon::OK; } maxon::Int32 polyCnt = op->GetPolygonCount(); The most funny part is that using a python script (that does use the same c++ function) works. And that's why I've opened a bug entry. I'll come back when I got more information. Cheers, Manuel

Thanks Riccardo.

I'm just going to go ahead and mark this as solved. Either using an empty Basecontainer or the set function solve the problem. Thank you for explaining!
