Cutout animation IK chains，Why there is no function？
Follow the tutorial to do, no function？

enter image description here

    The godot I used was 2.1.3. Windows 7 (x64).

    Bones can be rotated, IK can be set, bones change yellow, but IK doesn't work.Now my can only use the method of rotating bones to set the action.Even though I use tutorial ready-made example ,but doesn't work, and I've asked more people online, and  There are The same problem. 
    I don't know why?

Not sure about 2.1.3, but I think IK were removed from Godot 3 for now and are planned to return later (possible Godot 3.1) with a new implementation.

Need more information. So, what exactly doesn’t work? What version of Godot are you using?
