Hello!
I currently have a very simple mechanic to rotate an object using my gamepad thumbstick, I was wondering how i could instead rotate the hand bone, by using IK, which if I’m not mistaken should also rotate the arm and all the bones behind it if needed to make it look better, the object that i am currently rotating i will socket it to the hand and this will be to make my inspection system. Thanks a lot, this might be a pretty stupid question as i have never really worked with rigging
The bone controlled by IK will only have it’s position set by the ik. When you set the position it will change rotations up the arm. You can control the rotation separately. When I make a control to control the ik I both set up the ik node to control the position of the hand and add a set rotation node connecting the control to the hand as well so that one control and control the arm through ik, and the wrist through rotation. If you want to the rotation of the wrist to control the rotation of the shoulder and angle of the elbow, you will use a pole vector, you could parent the pole vector to the hand controller as well
Ok, Sorry I didn’t quite understand 
So basically by using IK,when moving or rotating the hand, also the arm shoulder ecc… would move, but like what nodes should k use in the graph? I understand it’s not as simple as checking a thing like “use IK”, when moving or rotating the hand, but how do i do that? Thanks a lot sorry for my ignorance
