I remember in C2, pin behaviour had different pinning methods, like rope style, lever style etc. This seems to be missing in C3. C3 also has hierarchies which already duplicate pinning behaviour, so without the different pinning methods, pin behaviour seems redundant and deprecated.
I am wondering why pin behaviour exists. Is it only for running C2 projects?
Also, how can I replicate different pinning methods present in C2 either by hierarchy or pin behaviour? Or do I have to use something else instead and/or write my own pin mechanic?
