You need to call NodeData.InitAttr() in NodeData.Init. E.g.: def Init(self, node): """ """ self.InitAttr(node, float, c4d.PY_TUBEOBJECT_RAD) self.InitAttr(node, float, c4d.PY_TUBEOBJECT_IRADX) node[c4d.PY_TUBEOBJECT_RAD] = 200.0 node[c4d.PY_TUBEOBJECT_IRADX] = 50.0 return True But you should check the allocation problem first, it is the most likely culprit. Se the edit in my last posting. Cheers, Ferdinand

@C4DS @kbar @ferdinand - Thank you so much for the in-depth responses. @kbar I'll see if I can get my employer to pony up for a license for Call Python as that seems like the simplest root. Although, this is potentially a light enough lift that I can finally make the transition into C++ development. @ferdinand Helpful to know that I won't be able to interrupt the save process (probably a good thing from the user POV).

Thank you @ferdinand for the detailed answer and code. I will do more reading in the sdk document.

Thanks for your quick replies I used GetBaseSelect() which allowed me to have the selected faces for each selection list_polygon = obj.GetAllPolygons() dim = len(list_polygon) L = [] tag = obj.GetFirstTag() while tag: if tag.GetType() == c4d.Tpolygonselection: sel = tag.GetBaseSelect() L2 = [] for i in range(0,dim): if sel.IsSelected(i): L2.append(i) L.append([tag.GetName(),L2]) tag = tag.GetNext() for item in L: print item[0] print item[1]

Hello! @ferdinand ,@Cairyn Thank you for politely teaching me! I was able to solve the title problem. I will use an external editor. I also understood loading plugins! I was restarting the software many times. I have a new question, but if you study a little more and don't solve it, let me ask you another thread. I'm really thankful to you!

Thanks to both of you! This helps alot! You guys are so nice and helpful

I actually found the solution while posting the question but wanted to still post it in order to help others who might have the same problem. (If this is against community guidelines I apologise) The solution is to use the CKey.SetGeData() method. Done!

@m_magalhaes Thank you for answer!

Mike, thank you a lot!

Thanks Maxime, "NOCAMERA;" worked, and the priority was a typo, now it does work!

Just one last comment on this licensing issue. I have a video that tells users how to install and license my own plugins for R21 upwards. It has been viewed 33,882 times as of today. It is my most watched video every month. I don’t have that many customers or sales. These views are from regular C4D users using Google to figure out what to do now since the old way is gone.

@m_magalhaes Thanks for the confirmation. I have meanwhile found that while the API doesn't cover the OM window states, you can still call CallCommand and IsCommandChecked on the functions. c4d.CallCommand(100004762) # Show Search Bar c4d.CallCommand(100004719) # Show Path Bar c4d.CallCommand(100004746) # Show Filter They only address the last used OM though; it doesn't seem to be possible to target a specific OM (like it is possible with the Open/Close flags which are stored as NBITs). And of course it doesn't tell me anything about the current visibility of an object in the OM. If the developers will think about commands to cover the filter/search/root conditions, they may want to go one step back and think about a more general concept to handle the multi-copy windows (Object Manager, Attribute Manager, Timeline) in some way that allows me to ask what was the last window, the active window, a window by index.

Unfortually no you can't.

Hi @orestiskon, thank you for flagging the topic as answered. Cheers, Ferdinand

Correct, thanks for poitning it I will add a task to improve documentation of Custom GUI
