      S

      @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?

      Hello @CJtheTiger,

      I am not quite sure how your question is meant, and generally new questions should constitute new topics.

      When you are asking, if when there is an ID_FOO: int = 12345 in V1, if we then just silently switch out the numeric value to ID_FOO: int = 54321 in V2, then the answer is sort of yesn't.

      We try to keep identifiers persistent. And for things like plugin IDs this is true without ifs and buts. I.e., once Ocube: int = 5159 has been defined, it will stay like this. But parameter values, e.g., PRIM_CUBE_LEN: int = 1100, can technically change. The goal is also to keep them persistent but in ABI breaking releases we sometimes have to modify descriptions. That is why we recommend that you always use symbols and not numbers.

      Cheers,
      Ferdinand

      Hey @blkmsk,

      I did not say that your posting was messy 😉 I of course understand that one sometimes can get a bit overwhelmed when in the middle of things, and that it is then quite hard to be super organized. As I said, it was clearly visible that you put effort into this.

      Regarding your bug isssue. In general, I do not like interfering too much with other devs work, and something in our bug tracker being marked as fixed, does not necessarily mean that it will make it into a release. But I pulled up your bug issue #604301 and there is long discussion between devs and QAs going on. Our build system made a comment roughly 72 hours ago, that a fix has been submitted, and shortly after that that is has been fixed (i.e., the build suceeded).

      This is however only a fix, not a verified fix (i.e., no QA has yet confirmed that what the devs came up with actually fixes the problem), it could still be rolled back. For details you better talk with end user support when this is urgent for you. Alin from end user supports seems to have handeled this.

      Cheers,
      Ferdinand

      Hey @CJtheTiger,

      Thank you for reaching out to us. That seems to be part of what the Cinversity team did before I joined Maxon. This was never a project of the SDK team. And more over, this seems to have been a private project of Niklas Rosenstein, an ex Maxon employe, because the link points to his GitHub. Niklas is still on GitHub, maybe you can send him a message if he still has his old code? But this looks like an R25 or even older project, so this will for sure require some update work.

      There are also the Cinversity legacy downloads on Maxon's downloads page, but it does not seem to contain it either.

      Cheers,
      Ferdinand
