That means for example, that you can change the segmentsnumber of a sphere at
any later time (as long as you didn't do anything else to it). Did I get that

> If anybody is familiar with the way C4D handles newly added objects of certain

> I implemented a very crude version of this behaviour when we started doing
> addon scripts, but the script could not enforce the lock (making this system
> kinda wonky).
