Thank You @m_magalhaes very helpful! I succeeded. I should have been able to figure this out from the example in the API. I've used the code basically as you have it with my spline datas saved in different hyperfiles. I then load that data from my tag. Thanks again.

@fwilleke80 as i mention in the other post, the problem (at least with our raycolider) is that if your ray hit an edge, it will hit 2 polygons at the same time. If it hit a point, it will hit <number of polygons attached to that point> times. It can be good enough but you have to be careful if you really want something solid. Cheers Manuel.

@zipit Thanks for the response and clarification. Works as expected @m_magalhaes Sorry about that. Will be more careful next time.

hello, thanks @zipit for answering the question and thanks you both for the kinds words Cheers, Manuel

Thank you for your help !

Thank you for the help @m_magalhaes

hello, happy you found your solution, and thanks for the feedback Cheers Manuel

@s_bach RE: You have to find a way to avoid that unnecessary rebuild of your layout after user interaction in your dialog. I'm not really sure how to do that. Since I just butchered the code from a sample plug-in. That will probably a problem for another thread. Anyway, it's functional at the moment. I'll settle for this. Thanks again and sorry for the trouble. Will close the thread now. Have a great day ahead!

Hello, I tested it with the Gradient Shader example from the cinema4dsdk and it works fine as far as I can tell. I just removed the check for ASSETDATA_FLAG::TEXTURESONLY: Bool SDKGradientClass::Message(GeListNode* node, Int32 type, void* data) { switch (type) { case MSG_GETALLASSETS: { AssetData* const assetData = static_cast<AssetData*>(data); // checks if only texture assets should be added if (assetData == nullptr) return true; BaseList2D* const baseList2D = static_cast<BaseList2D*>(node); if (baseList2D != nullptr) { // get the file name const Filename path = baseList2D->GetData().GetFilename(GRAD_FILE); // check if the file name is set if (path.IsPopulated()) { // add the file name assetData->Add(path, nullptr); } } break; } } return SUPER::Message(node, type, data); }; Regarding Shader hierarchies: I guess you can send the message to your child-shaders yourself, to make sure they receives the message. best wishes, Sebastian

Thank you both for the replies! Between both of them I have exactly what I need, thanks.

@m_magalhaes said in Add/Remove Groups of User Data: Hello, I was also talking about something like this. But it's not the best way to go. I suggest a TagData (plugin) with his own UI. pyTagCode = '\ import c4d \n\ #Welcome to the world of Python \n\ \n\ def main():\n\ print "this ia a message"\n\ \n\ ' import c4d # Main function def main(): if op is None: gui.MessageDialog("Please selecte a target object") tag = c4d.BaseTag(c4d.Tpython) tag[c4d.TPYTHON_CODE] = pyTagCode op.InsertTag(tag) c4d.EventAdd() # Execute main() if __name__=='__main__': main() By the way, don't forget you can save tag presets, that include python tags. You can simple add them with right click on your object in OM and "Load tag preset" Cheers, Manuel Oh this is good to know! Thanks so much for the information, this is quite helpful! Matt

hello, If you have nothing to add, this thread will be considered as "solved" tomorrow. Cheers, Manuel

hello, Thanks a lot for your feedback and happy to see your issue resolved. Cheers Manuel

Hi Sebastian! Thanks for you quick reply. He will try and reduce the code as much as possible (as it is a commercial project of your company). When he's done, I'll send it over. I am aware that you can't do much without example code. We were hoping there were some common stumble stones you might have come across. Another thing worth mentioning might be that the linker only fails when building on macOS. Windows is doing fine... Cheers, Frank

@m_magalhaes said in Add Position Velocity Port: Hello, Sorry for the late reply. This was a bug (with other ports also) and it's fixe for the next release. Cheers Manuel @m_magalhaes Ah OK! Thanks for lettings us know!

Thanks, m_magalhaes!

Also, if you want to move a tag, you first have to remove it from the original object. So you don't insert, you change the position of the tag in the scene graph. doc.StartUndo() doc.AddUndo(c4d.UNDOTYPE_CHANGE, tag) tag.Remove() op.InsertTag(tag) doc.EndUndo()

Hello, without seeing your code or any error message it is impossible to give any advice. But "works in viewport but not in rendering" sounds like you are using c4d.documents.GetActiveDocument() somewhere. See also BaseDocument Manual. best wishes, Sebastian
