@m_magalhaes Thank you for the explanation: "The points are stored in a local space (local coordinates)." Printing the three version of points space was really helpful The code works as expected!

@m_adam Thanks Maxime. Your example really shows that the cache must be built independent of how much processing it takes. Leaves me knowing that there must be something wrong on my modifiers, and indeed there was. I was checking if bt != nullptr inside ModifyObject(). I remember I copied this from some example, and it was interrupting the modifier to process. When the script is over, it would fire again with bt filled and finish deforming.

Sorry for the delay! Thanks for the help; I did manage to get it working. The ability to drag any control to the console is very useful, so thanks for that tip in particular. I'll take a look at those links, Maxime. Sorry for the hassle.

@m_adam said in Access the Limit Min/Max in the User Data Manager: In conclusion, you can't drive the enable/disable status of the limit checkbox since this is fully handled by the User Data Manager GeDialog, but you can simulate what this dialog does. Still a bit over my head but thanks for the clarification. So the code pointed above is to simulate what the dialog function.

hello, @baca To help us keep things clear and organized (and tracked), can you please open your own thread referring to this one and ask your question there. Thanks and Cheers. Manuel

Hi Shellan, thanks for reaching out us. Assuming that you refer to the Python general function c4d.storage.LoadDialog() at the current time you can't specify a file format since the value passed as force_suffix even is present is ignored - as written in the documentation - . Best, Riccardo

@mp5gosu I have one last question. on the thread for custom nodes that you mentioned above there was a file which was posted from Niklas. https://raw2.github.com/PluginCafe/examples/master/treeview/custom-nodes/custom-nodes.cpp Since this file was not there anymore and most probably it was a full code of what I am asking for, can it be that you or someone else might have that file somehow? That would be a great help. Thank you.

Ah I think you're right - I take the object right from the document without a clone or anything. Thank you!

I understand, that makes sense to me. Thank you for the help. Dan

I figured it out. The missing piece is a listener that's supposed to be added in main(), something like: def main(): obj = op.GetObject() bc = c4d.BaseContainer() obj.AddEventNotification(op, c4d.NOTIFY_EVENT_MESSAGE, 0, bc) The reason why this was not so obvious earlier today is that I read somewhere that there was no need for adding listeners in main(), that I would be adding unnecessary tasks. This is probably my fault, I may have misinterpreted or assumed things from a different context. But, to my defense, I must say that the code that works has no listeners in it. Have a look! Well, this is where it gets tricky: the listener code had been there indeed, but I had erased it after a few iterations(because I thought it was overkill). This means that the listener is still working despite the fact that I had it erased from the Python Tag code, in other words, it's garbage. I hope this helps other users as well as the Maxon team(you guys rule!) Thanks for your time, Leo

Hi Manuel, perfect - in the Script Manager everything works as expected. Running the code via python tag isn't important to me - I just wasn't aware of this difference ScriptMgr <> PythonTag concerning the execution of the code. Thanks a lot for your solution ! Cheers, Jens

Hi Ogers thanks for reaching out us. With regard to your request, I confirm that to deliver the desired functionality you've to stick to TreeView since it's not possible to disable items belonging to a SimpleListView. Cheers, Riccardo

@m_adam oh，i miss this reason，thank you : )

@m_magalhaes said in User Data button Python Tag r19 - avoid "index out of depth" console feedback: if desc_id.GetDepth() > 1 Thanks a lot, Manuel! It's perfect now.

@r_gigante Thank you for your answer! it s all fine : )

A CRC or a Checksum is basically a way to uniquely identify data. https://www.howtogeek.com/363735/what-is-a-checksum-and-why-should-you-care/

Hi Pim, thanks for reaching out us. With regard to your question, given for comments from Cairyn, I recommend to refine your approach and to look on the web since there are a few different strategies to find the largest inscribed rectangle in a non-convex polygon (among them I recommend having a look at this). With regard to the points walking direction for a given polygon this is defined by the polygon normal and the left-hand rule and it should definitively not be randomly defined. Cheers, Riccardo

Hi @bentraje, since you rotate the axis (with SetMg) you also need to update the tangents according to the correct axis since tangents are in local space of points positions which are also in local space of the object. But as you figured is more rigging than a programming issue. And if you already solve the issue congratz! Cheers, Maxime.

Hi @blastframe, I can only confirm what's @mp5gosu said, and confirm that c4dpy is a complete Cinema 4D executable, just opened as a python interpreter mode. So nothing to do here, unfortunately. Cheers, Maxime.
