Apologies, I thought my mention of the Voronoi Fracture's ability to generate vertex map tags (itself being a generator that deals with variable geometry) would be clear enough, but I suppose a casual mention doesn't suffice for an app this complex, haha!

Yeah, it's really all about overcoming that immutable nature of the vertex map tag. I'm generating them on parametric objects and I need them to be able to adapt to changing point counts. Just like they're able to do on editable polygon objects. Which means I have to create a new tag each time the host object's geometry changes and update anywhere else it's linked. That's where TransferGoal() comes in.

Where my function was failing was a result of TransferGoal() not only updating the BaseLinks, but also the variables within my code. So in my function, once TransferGoal()is called, both vmap and replacement_tag variables end up referencing the same tag (the new one), leaving me without a variable filled with the old tag to delete.

Passing True as the second argument left my variables alone and only updated the links, essentially making it work perfectly. So passing True or False to TransferGoal() didn't make any difference as far as the BaseLinks were concerned. Those always updated correctly. If I had to guess I would say it has to do with the memory addresses of the objects being transferred... which is just more reason to avoid ignoring that little instruction in the sdk;) I'll trust the devs on matters of memory handling lol.

Turns out it's quite easy to work around. Since I insert the new tag directly after the old tag I can simply use GetPred() to find the old tag and successfully delete it.

As far as your question as to whether I would consider this desirable or expected behavior, I would say no. I would much prefer that my in-code variables remain as they were before calling TransferGoal, because as it currently is I'm left with two distinct variables that hold the same object. In other words, I'm left with redundancy and it ends up preventing me from doing more to the old BaseList2D object. In my case, it happens to be relatively easy to re-find and re-reference that BaseList2D object, but that might not always be the case.

But yeah, now I have a working skeleton function (that doesn't break the rules lol). Just gotta bulk it up with appropriate checks and I should be good to go!

Thanks for your help @zipit!

Cheers!
