I have family with chain made by Physics revolute joints and trying to increase or reduce chain size in runtime.
Tried a lot of options (Pin, Hierarchy, set positions, ...), but every time it come into conflict with Physics behavior.
After that I tried with making Physics objects immovable and it worked during scaling, but after making objects movable, after scaling, at first they behave a little strangely, with some extra forces, before they stabilize, but that doesn't suit me.
At the end I tried with scaling entire Layer and it works fine but, it changed layer positions because Layer pivot points is at the center of the layout. After that I tried to move family objects, to offset Layer scale but got the same situation as before.
What should I do? Is there a maybe way to change Pivot point for one layer only, or how to work?
