    Hello @fss, Thank you for reaching out to us. We unfortunately cannot help you with this question here in the SDK Team as you are asking effectively for a feature in the Maxon App. While the C++ SDK has some licensing features, they are restricted to reading data, so you cannot just call an API to release the licenses yourself. You should ask your question to user support, because they are the right place for things concerning the Maxon App. What you might want to clarify there is what you mean by "defunct instances" and which app you are using. I assume from the context that you are using c4dpy with some Python scripts which sometimes crash c4dpy and then the license is not being released correctly. Which sounds like a bug which you then should report to user support. Cheers, Ferdinand

    Hello @indexofrefraction, Thank you for reaching out to us. FYI, developers.maxon.net is down since about 24 hours.... We were aware and were working on it, the site should now be accessible again. Please excuse the inconvenience. Cheers, the SDK Team

    Hi All, Thank you so much for your interest and taking the time to apply. We ended up with more applicants than could fit in one workshop. If you received an email from me (Maybe in your spam folder? look for d_keith ) you've likely been accepted. If not, I do intend to host similar workshops in the future. Candidates were given priority based on: Prior programming expertise in C/C++/Python or similar languages. Interest and ability to actively participate in the lectures/homework projects. Availability to potentially create capsules for the Maxon Capsules Library in the future on a freelance basis. And for auditors, special preference was given to MAXON employees who will be documenting/developing/training Scene Nodes workflows. I hope to host similar workshops in the future and will prioritize previous applicants at that time. Sincerely, Donovan Keith

    Hello @atticuslv, as indicated in my last posting, this is not a programming question, as you do not invoke any of our APIs, and you should reach out to customer support with that question. We only deliver API related support here. Cheers, Ferdinand

    Hi... I'm trying to figure out how to handle nested LayerShaders mat.InsertShader(gradient_shader, sha_xlayer) inserts gradient_shader as a child of sha_xlayer ? Would sha_xlayer.InsertShader(gradient_shader) do exactly the same thing ? If yes, does mat.InsertShader(sha_xlayer) have to be done first as well, or can you set up a shader tree first and then add it to the material? best, index

    Hello @sucky012, welcome to the forum and thank you for reaching out to us. This is a forum dedicated to plugin programming for Cinema 4D. The General Talk forum is our sort of Off-Topic forum, but your question is even out of scope for that. We will let your question remain in the forum, but you will not get an answer from the MAXON SDK Team, as Cinebench is simply not our area of expertise, and it seems also unlikely that the community will be able to answer this. When you want end-user support, you should contact them via a support ticket. But I somehow doubt that CINEBENCH 15 is still in the support cycle. But I might be wrong about that. Cheers, Ferdinand

    Hello @prowl, Welcome to the forum and thank you for reaching out to us. I am not sure how your posting is meant. Are you looking for a developer or are you looking for support for developing a solution yourself? If the latter is the case, then you are posting in the wrong sub-forum. When you are indeed looking for a developer, then you are in the right forum. If this is a task which you could solve on your own depends on the details of what you want to achieve, but the principal logic is not that hard to realize. Assuming that you want to implement your idea in Python: Use c4d.utils.SendModelingCommand and the command identifiers for Current State to Object and Connect and Delete to collapse some geometry as you would do it manually in Cinema 4D. Use c4d.documents.SaveDocument with c4d.FORMAT_STL_EXPORT to export the output of the modelling commands. As lined out in the forum guidelines, we cannot design applications for users. There can be things which complicate this simple task (like for example collecting dependencies in a scene). If you do not want to take the risk of being overwhelmed by your task, you should hire a developer. In general, I would say this is a manageable task for a beginner. The Maxon SDK Team will be happy to answer further questions when you decide to implement this yourself. But you must provide code and specific questions related to our APIs. Cheers, Ferdinand

    Yeah, I understood that. I did not take any offense here; I just gave a little insight into why I sometimes simplify things to a degree where an expert might say: "But this is not quite right!". I modified the sentence you had an issue with to: So, the Python approach (which is also used by many other languages) is more memory efficient within this simplified view, as you only must store a value once. To more clearly indicate that this is an abstraction. I still would not point out that non-managed languages are effectively more memory efficient than managed ones, as that is not the subject here and actively obfuscates one of the reasons why this is done in these managed languages: To save memory.
