so I finished making a caterpillarand I wanted to make controllers for it's rig.

I looked up some tutorials on YouTube but they said to change the IK Settings to "ikRPsolver" so I can use a controller via "Pole Vector". The Problem with that is, that everytime I do that, the joint turn by 90°.
It would be really great if yomebody would know some solution.
