@m_adam good to know, thanks.

Hi @m_adam , That's sad... Thanks, anyway.

Hey @m_adam, I never thanked you for your very helpful and thorough reply, so allow me to do so now: thank you very much! Your reply ended up being extremely useful, as it guided me in implementing the KD-Tree within my Python script, as well as helping me convert the Barycentric coordinates to UV coordinates. So, for that, once again; thank you! Now that this is implemented, I am faced with a challenge: it appears that the precision of the drawing of the Spline greatly depends on the subdivision/triangulation level of my geometry (for example, the Sphere in my parent message). In other words, if the geometry whose UV map I am drawing the shape of my Spline onto is very low-poly, the drawing of said Spline will be incredibly imprecise. It seems like the precision increases as I increase the amount of polygons on the geometry. Just curiously, without necessarily pasting my code here, I was wondering if - at the top of your head - this behavior was to be expected? Does this mean that, with the KD-Tree and Barycentric conversion method, I would never be able to programmatically draw a perfectly round circle Spline on a Plane object that, despite having a perfect UV map, only has 2 polygons? I can work around those constraints, but it'd be great to know if the current imprecision of my drawing approach isn't caused by something else. Thanks!

@i_mazlov Thank you very much for your response! I am not sure how long it would have taken me to figure out the "prefsPlugin: c4d.BasePlugin =... " part without your help. This is the code I wrote, which works exactly how I wanted it to (and now I have the script mapped to a hotkey). import c4d def main(): prefsPlugin: c4d.BasePlugin = c4d.plugins.FindPlugin(c4d.PREFS_NAVIGATION, c4d.PLUGINTYPE_PREFS) navigationValue: int = prefsPlugin[c4d.PREF_NAVIGATION_CAMERA] if navigationValue == 3: prefsPlugin[c4d.PREF_NAVIGATION_CAMERA] = c4d.PREF_NAVIGATION_CAMERA_CAM else: prefsPlugin[c4d.PREF_NAVIGATION_CAMERA] = c4d.PREF_NAVIGATION_CAMERA_CUR if __name__=='__main__': main() Thanks again!

Hi @i_mazlov , Thanks for your time, sorry for my bad that I use a confusing word for "id", I should say "asset id", but as you said, I can use ID to check this, for some reason, I overlooked this for a moment. And the GetParent(), I found out that the culprit is GetSelectedNodes(), I use this to get a selected node(abs bode) but the return is "group", so what ever I try the return is 'Root'. Thanks for all your works! Cheers~ DunHou

Hi Christophe, Please note our Support Procedures, namely: We cannot provide support for third party libraries "It doesn't work" is not a support request and we cannot debug your code for you, but instead provide answers to specific problems. From my personal point of view, you need to reduce your setup as far as possible while still being able to reproduce the bug: Determine which one of your 2 tag plugins causes the issue Cut off unrelated functionality of your plugin that has nothing to do with the issue Figure out the specific function or line that causes the issue Search the forum if this issue was already discussed If not, create an example code snippet that highlights your issue Post your specific question and the example code snippet in a separate thread with a meaningful title Cheers, Ilia

Hi correct I made a typo in the string representation of a Vec3, this is going to be fixed in an upcoming release. Cheers, Maxime.

Hello @Christian-0, Thank you for reaching out to us. I am a bit confused by your question. A soft body simulation is characterized by the fact that it gives up the idea of a geometry transform with governs a geometry as usually applied in computer graphics. In the end this means that the transform of the object (BaseObject.GetMg) will not change but the points will and with it the bounding box of an object. Below you see a soft body cylinder falling. Its transform, the axis, never changes, but the bound box does. Animated are here the points, not the object, hence the term soft body. bbox.mp4 In the API you can get the bounding box values with BaseObject.GetMp and BaseObject.GetRad. When you want a transform, a matrix for that, you would have to compute that yourself. The matrix manual dissects how to construct matrices. Cheers, Ferdinand

@ferdinand Thanks for your help!

Hello @Dave , Welcome to the Plugin Café forum and the Cinema 4D development 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 Guidelines, as they line out details about the Maxon SDK Group support procedures. Of special importance are: Support Procedures: Scope of Support: Lines out the things we will do and what we will not do. Support Procedures: Confidential Data: Most questions should be accompanied by code but code cannot always be shared publicly. This section explains how to share code confidentially with Maxon. Forum Structure and Features: Lines out how the forum works. Structure of a Question: Lines out how to ask a good technical question. It is not mandatory to follow this exactly, but you should follow the idea of keeping things short and mentioning your primary question in a clear manner. About your First Question Your question is effectively out of scope of support because we do not debug code for users as lined out in our support guidelines. So, you cannot just post your code and then ask us to fix it, this especially applies when things like Chat GPT are involved. With that being said, there are two (three) major problems with your code: show_script_list_dialog: This is pure nonsense regarding creating and running a dialog. Dialogs must be implemented, see here for our dialog examples. run_script: This does not set the runtime environment, the globals, of the script to run. Which will cause many scripts to fail, as script manager scripts are prepopulated with doc and op. Plugin ID: The plugin ID 1009792 you are using does not seem to be a valid ID, the current plugin ID counter is at 1062027. You can do whatever you want to do locally, but you cannot ship any plugins with such made up IDs. You also do not really need a full-blown dialog here, you could just get away with ShowPopupDialog. Find a simple version below. Please understand that we cannot support ChatGPT nonsense output in future postings of yours. Cheers, Ferdinand Result: Running the twice hello_doc.py script with the wrapper script run_scripts.py. And then for the lulz run the wrapper with the wrapper to run the hello_doc script. metalol.mp4 Code: """Demonstrates how to run Script Manager scripts from a Script Manager script.

Hey @i_mazlov, thank you so much for your incredibly helpful and thorough reply. This is exactly what I was looking for. Thanks again! I really appreciate it!

Dear Ferdinand, Thank you so much. I've found it tricky to navigate the API reference. Being able to get a pointer to the object parameter through drag and drop is a game changer for me!!

@ferdinand Thanks again I'll have time to check it later today. But it seems clear.

Hi @baca VC_SAFETY has been removed in 2023.1, you do not need it anymore, since the message can't fail anymore. You should keep it for old code but for new code, just leave the vc_flags empty will be enough. Cheers, Maxime.

@ferdinand Thank you very much for the expanded object.

Bummer. But thanks, Maxime, for the quick reply.

Hi @ferdinand, thanks for taking the time to clarify that Okay, I see. So one can view this "behavoiur" as intended since it is the result of the math behind how the circle spline is calculated? Still I wonder why the circle spline primitive with 1 intermediate point, i.e. with four control points doesn't appear like the n-side spline with 8 sides? Wouldn't it be "cleaner" that way? Regading the true values - I am well aware that the repr of c4d.Vector rounds in the GUI. It was only that those values were quite off compared to the values of the points of the n-side spline. That's why my initial question arose. Interesting and good to know that rotating points via sine and cosine is slow and no good option. Thank you for that insight. May I ask why that is? I mean why is c4d.utils.MatrixRotZ better? What does that function do differently in terms of performance? In the end it has to do the math as well, does it not? Sorry for constantly asking all this stupid questions. It is only that I want to understand these things thoroughly. Thanks for your time, Sebastian
