1. IK for an arm with roll bones.
The arm has two roll bones, for upper- and forearm (dark green in the picture). Now, the IK for the left chain will obviously not behave like an arm. I know I can just have two bones like on the right, but the question is how do I properly set up the constraints?
The roll (x rotation) of the upper bone (dark blue, right) should only affect the roll bone (dark green, left) and not the main bone (dark blue, left), whereas everything else (yz rotation and translation) should affect only the main bone.
2. Move hips but have the feet stay where they are.Hidden content: [ Show ]
Let's say I have a standard 2-bone chain with default IK effector. The chain is a child of the hip bone. Is it possible to have the hip bone move with the leg end effector trying to stay at the same position? So that when I move the hip down the legs would bend instead of staying straight and just being translated down?
I hope the questions are clear, if you need any more clarification, just ask.
Thanks in advance.
