    Yes, I must read the manuals more throroughly (RTFMS). Excuses: it is so much and I just wanted to compiler R20 in R21. But you are correct. BUT, adding iferr to the code worked, AND also solved the other issue. Everything is working now! Thanks!

    hi, that really depends on what you are doing. There's different type of lock for different cases and scenario. That also depends on what you care first, speed or memory. but the manual is pretty easy to understand, just pass the lock as a reference to your lambda function and you should be good to go.

    Hi @lasselauch there is actually no plan to update ResEdit. There is the R20 Resource Editor but for the moment it's only for Node stuff. Cheers, Maxime.

    Hi Pim sorry for the late reply, this is possible by using the lib_py.h (typically this is somehow what we used before R20 to expose feature in python, but it's way elder, not everything is possible to do, you have less control than with the new python.framework, and the lib_py.h is not maintained (so don't expect any enhancement in it) Only the python.framework will be enhanced. // Init Python GePython pythonScope; pythonScope.Init(); // Acquiere the GIL GePythonGIL gil_state; pythonScope.SetNode("doc", doc); // If doc->GetFirstObject() is nullptr, op variable will not be declared in the python scope, and you cant add a None. pythonScope.SetNode("op", doc->GetFirstObject()); maxon::String pythonCode = "\ import c4d\n\ \n\ def main():\n\ print(doc, op)\n\ \n\ if __name__ == '__main__' :\n\ main()\n\ "_s; StopAllThreads(); pythonScope.Run(pythonCode); Cheers, Maxime.

    Thanks again @PluginStudent for helping me so quickly. That was enough information to help me find the .MakeUserSpline function that allows me to do exactly what I'm after: MakeUserSpline('sin(x * PI)', 5) More info here for anyone looking. Cheers, Jamie

    Hi, yeah like that. __name__ is just another module bound constant attribute. It is a dunder attribute, signaling a special importance, indicated by its double underscores, but that is only a convention and not a functionality. You can set __name__ to anything you like, just like you could set __author__ to your favourite ice cream brand. The convention dictates that __name__ tells the script in which context is being executed, where __main__ should signal that the module is executed directly. You could set it to my_cpp for example, so that your scripts could react differently to being executed from your C++ code. Cheers, zipit

    To summarise, there are 2 projectdefinition.txt files. on main / sdk level, Define which project (plugins, etc.) Example: Platform=Win64;OSX Type=Solution // defines the level of rigour of the source processor's style check stylecheck.level=0 Solution=\ plugins/cinema4dsdk;\ plugins/maxonsdk.module;\ plugins/commandline;\ plugins/CommandLineRendering on plugin level, // Configuration of a custom solution in the projectdefinition.txt file Example: // Supported platforms Platform=Win64;OSX // Type of project Type=DLL // this plugin depends on these frameworks: APIS=\ cinema.framework; \ misc.framework; \ image.framework; \ core.framework; \ python.framework // Enable some advanced classic API support; not needed for hybrid plugins C4D=true // Plug-in code-style check level stylecheck.level=0 // Custom ID ModuleId=net.maxonexample.commandlinerender

    @r_gigante said in attribute 'nodiscard' requires compiler flag '/std:c++17': Well @pim , that's indeed the issue. Sticking to the recommended IDE is always recommended. Indeed going back to VC++2015 solved the issues. But now I have problems with the python.framework. See https://developers.maxon.net/forum/topic/12439/reading-script-file-into-memory/8

    hi sorry it wasn't clear enough. yes sure, doing documentInfoData->doc->GetDocumentName() is the same as doc->GetDocumentName() I've updated the documentation with Save Project with Assets to be a bit more clear. Cheers, Manuel

    Hi, I often use the python generator to create some prototype myself. So it's ok for me. But if you want to give or sell your result, you should move to a plugin. It's not hard at all, if you already did that prototype, the plugin is easy, and we are here in case you have some issue. Nice result Cheers, Manuel
