I made some progress now, I changed the message type to be MessageData, to retrieve Core messages and in the websocket layer I now use SpecialEventAdd() with my own event ids, I see that the CoreMessage() method also supports the BaseContainer as a parameter, is it possible to fill it with custom data when calling SpecialEventAdd()? The function only seems to take two Uints as additional parameters, how would I get some custom data into my own CoreMessage method call?

Thank you again! 🙂

Hi the C++ one is the most up to date version, thanks for pointing it.

The Python doc will be updated.
Cheers,
Maxime.

@m_adam oops, sorry...yeah wrong forum. Went to Cineversity.. thanks

Hi @m_adam, following your typescript example it worked now to connect! Thank you very much for your help 🙂

Merry Christmas and a Happy New Year!

Thank you for the detailed reply, @i_mazlov!

I was unable to determine the root cause of the issue, however I was able to work around it by preloading direct dependencies with a FileExecute call and using the SearchPath Windows function to locate the runtime dependency DLLs and pass the absolute paths to LoadLibrary (I'm aware this is not recommended, but should be fine for this internally used plugin).

I couldn't find anything in the newly added Maxon options that appeared to affect the loading behavior. My only remaining theory is that the new licensing process is indirectly triggering this behavior:
LoadLibrary function returns STATUS_DLL_NOT_FOUND error on impersonate thread in Windows

Thanks again!

Hi @Kantronin,

Instead of creating multiple consequent postings please consolidate them in a single one. I've also noticed that you've added "programming" tag but haven't mentioned the language you're talking about (is it c++ or python?).

Regarding your questions. Transforming the axis of a PointObject effectively means transforming the point values. There're some helping commands that I've shown you in my previous message, but what they effectively do is just transforming the points. Please have a look into the operation_transfer_axis_s26.py example, which demonstrates how to perform axis translation.

As for the rotation part, I'd need to point you once again to our Matrix Manual, which actually contains the answer to your question. Namely, the chapter "Constructing and Combining Transforms" explains the usage of functions c4d.utils.MatrixRotX(), c4d.utils.MatrixRotY() and c4d.utils.MatrixRotZ(). I will not copy & paste the same code snippet from our manual, so please check it youself.

Combining these with the example above should do the trick for you, unless you don't have the initial transformation of your ring splines. If that's the case, then your task turns into a way more complex form of the optimization problem.

Please also note, that you can only do the object axis transformations on PointObject (and on PolygonObject since it's inherited from PointObject). This effectively means that if you're using the Osplinecircle instead of an ordinary Ospline, this wouldn't work, as it doesn't store any points inside. In this case you'd need to convert to Ospline. If that's not an option for you, you can check the Geometry Axis and Geometry Orientation scene nodes, as they allow you to transform the axis "on-the-fly", so this would work even with non-point objects.

Cheers,
Ilia

Hi @i_mazlov
I can't use C++ at the moment, so I thought I'd try MultilineEditText for my purposes.
I looked for This post in the forum and now I have some ideas.
Thank you for your reply!

Cheers~

Hi @shahir-zaman ,

Welcome to the Maxon developers forum and its community, it is great to have you with us!

Getting Started

Before creating your next postings, we would recommend making yourself accustomed with our forum and support procedures. You did not do anything wrong, we point all new users to these rules.

Forum Overview: Provides a broad overview of the fundamental structure and rules of this forum, such as the purpose of the different sub-forums or the fact that we will ban users who engage in hate speech or harassment. Support Procedures: Provides a more in detail overview of how we provide technical support for APIs here. This topic will tell you how to ask good questions and limits of our technical support. Forum Features: Provides an overview of the technical features of this forum, such as Markdown markup or file uploads.

It is strongly recommended to read the first two topics carefully, especially the section Support Procedures: Asking Questions.

About your First Question

Assuming that what you're trying to achieve is to toggle the "UV Grid" option
d09d5b8d-51a2-4a6a-9618-90b2dbcc6638-image.png
You effectively have two options:

The easiest one is to execute CallCommand(170776) (you can find the command ID in the Script Log) The more involved but also more flexible way is to find the UV settings scenehook and go through all its branches (or may be not all of them, depending on what specifically you want to achieve). Please find the C++ and Python code snippets below.

Cheers,
Ilia

C++ commanddata execute function code snippet:

Bool MyCommandData::Execute(BaseDocument* doc, GeDialog* parentManager) { const Int32 ID_UV_SETTINGS_HOOK = 1053309; if (!doc) return true; BaseSceneHook* sceneHook = static_cast<BaseSceneHook*>(doc->FindSceneHook(ID_UV_SETTINGS_HOOK)); if (!sceneHook) return true; maxon::BufferedBaseArray<BranchInfo, 20> infos; sceneHook->GetBranchInfo(infos, GETBRANCHINFO::NONE) iferr_ignore("GetBranchInfo"); for (BranchInfo& info : infos) { if (info.name != "UVSettingsBranch"_s) continue; GeListNode* viewSettings = info.head->GetFirst(); while (viewSettings) { GeData value; viewSettings->GetParameter(CreateDescID(UV_SETTINGS_FILTER_SHOW_GRID), value, DESCFLAGS_GET::NONE); Bool valueBool = value.GetBool(); value = {!valueBool}; viewSettings->SetParameter(CreateDescID(UV_SETTINGS_FILTER_SHOW_GRID), value, DESCFLAGS_SET::NONE); viewSettings = viewSettings->GetNext(); } } EventAdd(); return true; }

Python script code snippet (special thanks to @m_adam on this one):

import c4d def main() -> None: sh = doc.FindSceneHook(1053309) for branch in sh.GetBranchInfo(): if branch["name"] != "UVSettingsBranch": continue viewSettings = branch["head"].GetFirst() while viewSettings: viewSettings[c4d.UV_SETTINGS_FILTER_SHOW_GRID] = not viewSettings[c4d.UV_SETTINGS_FILTER_SHOW_GRID] viewSettings = viewSettings.GetNext() c4d.EventAdd() if __name__ == '__main__': main()

Hi thanks for the question, I've opened a bug report, for the moment the only workaround would be to remove the Morph and re-add it.

For the moment the name in the treeview is only updated when manually edited from the treeview and on the insertion of the item in the tree view.

Cheers,
Maxime.

Hi sadly this is not possible. I've reached to responsible team to make them aware about it.

Cheers,
Maxime.

Thank you for your reply and solution！
Cheers~

@ferdinand I figured this issue out so you can mark this as solved/closed. Thank you.

Hi @yaya,

I see your point here and I can only guess if such behavior is expected or not, as this is (and I've already mentioned this to you earlier) a question that has nothing to do with development.

In general it sounds like a bug, so you're very welcome to reach out to our Support Team and ask them for a proper workaround if they actually classify this issue as a bug.

I'm moving your thread to general talk section in case someone from our community might be willing to share their experience on that topic.

Cheers,
Ilia

Hey @ECHekman,

I assume you are looking here for some kind of approval from my side? That looks fine, but it is hard to give a concrete assessment with mock code. But as lined out above, there is little which can go wrong here. Splitting up your data into sub-containers could help with access times when you plan to add lots of 'attributes' and 'pins'. So, it is good that you do that. And shifting your application IDs into lower ranges for Cinema 4D is probably not technically necessary but will lead to more 'natural' IDs. I cannot really see much going wrong here.

The only thing which is not so nice, is the unsafe C-style cast in BaseContainer *data = ((BaseShader*)node)->GetDataInstance();. We recommend using static_cast for safe casts and reinterpret_cast for casts which are explicitly meant to be unsafe.

Cheers,
Ferdinand

Well, my answer answers that, check out the posting I linked to. You must insert a MENURESOURCE_SUBTITLE:

menu.InsData(c4d.MENURESOURCE_SUBTITLE, "My Heading")

Thanks for your answer.

addendum, I briefly spoke with the dev:

In SetDParameter, there is code that sets the correct group automatically if force_type or force_type_mode is specified, and the other way around. One thing to keep in mind is that, when you set the parameter force_type_group, the mode is set to default value for that group, i.e., ball and socket for spherical, hinge for angular, slider for linear. This is what you see ig you play in with the dropdown menus in the UI as well. So, if one first sets force_type_mode and then force_type_group, the latter resets the mode to a possibly different value. But in the code snippet attached it looks though like the order is correct (assuming is the actual code used in the plugin).

In a way, I understand that if you are setting mode and group manually from you plugin and you know what you are doing, you are setting a combination that makes sense. But in general, to be extra safe, I decided to go with this solution, so if you change the group the mode is automatically set to something that makes sense. And, btw, also when you set the mode there is a check on the group, and if the values don't match it gets overwritten with the correct group.

so, valid options are:

simply set force_type (as before) set force_type_group and force_type_mode (in this order) only set force_type_mode (group set automatically)

If any of these don't give the expected combination it is a bug

I think he too struggled a bit with understanding what you did concretely, so I would recommend creating a bug report as lined out above.

Cheers,
Ferdinand

Hello @ECHekman,

Thank you for reaching out to us. When you run into compiler errors, you should always include them, because how should we otherwise help you? Sure, I could throw your code into our code base, guess some things, and then try to compile it, but the guessing and compiling is unnecessary and makes our answers more imprecise.

But this should work:

iferr_scope; maxon::String myString = "Hello/World"_s; maxon::BaseArray<maxon::String> parts; // could also be const myString.Split("/"_s, true, parts) iferr_return; if (MAXON_UNLIKELY(parts.GetCount() < 1)) return maxon::IllegalStateError(MAXON_SOURCE_LOCATION, "Splitting path failed."_s);

FYI: There is also UrlInterface::GetComponents.

Cheers,
Ferdinand
