hi,there , recently I am doing a character modelling and trying to create joints by useing character, btw I am using a win systerm pc ,and i found that everytime when I click ' Arm(IK/FK Only) ' , I get two kinds of joints ,one is IK and another is FK . I watched many tutorials and they only get IK , I dont know what I missed , tried many times , have no clue why I still get two kinds of joints , BUT when I use my macbook to do the same thing , I get the IK joints which is what I want . pls check the pic I uploaded , thank you
