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

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,

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()
