      Hi. Why does the Python tag or Python node in Xpresso crash Cinema 4D and how can I fix it?

      I created a crystal generator project where I use the Python tag to randomly assign generator and spline parameters, and use the Python node in Xpresso to assign the Redshift material(Crystall 1) parameter values ​​(I can't access these parameters via the Python tag). Certain SEED values ​​("Кристалл 1" user data) crash Cinema 4D.

        Hello @SmetK,

        Thank you for reaching out to us. Your file is not crashing for me, and you did not actually include your crash report. Please follow our Support Procedures regarding reporting Bugs and Crashes.

        Please also note that this is actually reserved for bugs and crashes caused by our API and not by user code. It is of course not out of question that this is caused by a bug in our API, but by for example violating threading restrictions, your code could also be easily the culprit. Please also understand that we do not run a debugging service here, you cannot just give us your code and expect us to figure out where and why it crashes. We expect some form of work on your side which pinpoints the problem to: "When I do this, Cinema 4D crashes, why?".

        Cheers,
        Ferdinand

            Just to be clear: I did not want to imply that we do not want to help you. But we need a little bit more from you. I would suggest to try to upload the crash report again. What is even better, is when you tell me a date and time (and your timezone) when you did submit a crash report (or a unqiue message you have put into the crash message).

              @ferdinand I just now noticed that the file attached incorrectly. At the time of publication, it's 6:00 PM(time of crash cinema 5:57PM), October 18th, Vladivostok time (UTC+10 (GMT+10)). The program crashes on random seed values. Am I correct in understanding that I can't change material parameter values ​​using the Python tag?
