Hi @khor unfortunately Fritz is in holiday, but from what I see this is not possible since few types are not public. I will confirm with him when he will be back, in the meantime I wish you a nice Christmas. Cheers, Maxime.

Good morning @ferdinand! I modified the whole code to always do my changes inside TagData.Message now instead of doing them in TagData.Execute, which should prevent any crash - even if I didn't got one, it seems far better to stick on the good rules and habit. Have a good day! Christophe

Yes that's what afraid to hear:) I did iteration over tags of Cache/Deform Cache and compare with GetOrigin() thingy to find related tag. I believe there should be some functionality in the SDK. Thanks for answers!

@Dunhou @ferdinand Gotcha. Thanks for the confirmation and illustration links.

@bentraje said in IsConnected Method Not Working As Expected?: P.S. Just some minor nitpick, both method does not return the same type. The first returns a list. While the second return an iterator. Not really a problem per se since I can just convert the iterator to a list. Just some FYI in case you are interested. Thanks a lot for reporting that, we will fix this as soon as possible

Hello @bstone, Thank you for reaching out to us and welcome to the Cinema 4D community. And thank you @bentraje for answering the question. We do not have to add anything here, @bentraje already pointed out all the important bits Cheers, ferdinand

@manuel gotcha. thanks for the confirmation.

Hey @joel, a 'dead' object means that Python tries to reference a node which does not exist in the C++ layer anymore, i.e., has been de- or reallocated. Since my function retrieves the tag on the spot and does not attempt to pass it outside of the function, it seems a bit unlikely that the tag is already dead, at least I am not experiencing any of this. Please provide the scene, code you are running, and the exact stack trace (do not forget to save your script first, so that the trace has the correct line numbers). Otherwise I will not be able to help you. Cheers, Ferdinand

@ferdinand Thanks for the outlining the limitation. For options Yep the replace command does not carry over the connection so that's a no go. I just went with the python route. Works as expected. Basically, I just deleted all the points of the spline object through the resize object. Then rebuild it again with the reference. No problem so far. RE: scene nodes. Uhm I really find the nodes implementation clunky at the moment and this is coming from a user who uses Houdini. No plans in implementing it at all in my workflow.And the pyro being implemented as a tag and not as a scene nodes set-up tells a lot that they are not confident in that workflow. Too convoluted for what it is trying to achieve and doesn't use "attributes" like what Houdini and Blender can. I find it as a "toy" at the moment rather than an actual production tool. Anyway, will close this thread for now.

I was able to solve it by searching the DescID in the Cloner Description with the Inheritance Name.

Thank you so much for the information. If further information is needed I will reopen this question.

Thank you so much. All further communications will be done via email.

@Manuel RE: This might happen if you changed Yep yep this is what I'm currently doing. hehe Anyhow, your code works. Thanks!

Hi @ferdinand, Thank you for the detailed explanation and the code. It works perfectly and the problem is solved!

Hi @ferdinand Thanks for the response and heads up on the crashes. RE: you want to control hair guide vertices programmatically Yep yep you are right on this part. Basically, have a geometric hair animated and simulated for preview. But rendered on the actual hair object. This is the workflow for other DCC, and the more logical one. This way you separate the hair source and hair generation. It's easier to debug. Anyhow, for looking at your python example, this should get me by on my current use case. Thanks for your illustration as always! Will close thread now.

Hi ferdinand, I am very sorry for my lack of reading the Guidelines properly. But still, very huge thanks to you for the explanation anyway. This already helped me. I will try things out and will probably come back here with some code.

Thanks, Ferdinand. I'll take a closer look as soon as I find the time.

Hello @ferdinand Thanks a lot for the code above, I really appreciate your help. I changed a few things for match what I was looking for and now it's working perfectly. Thanks again!

@ferdinand Thanks as always for the explanation. The illustration code works for my use case. Will close now thread
