I try to simulate a handling robot, but I cannot get the Rotation part of the Inversed Kinematics Constraint to work.
I built a very simple basic armature with 5 bones, I even left all bones all degrees of freedom, but STILL: when I rotate the constraints target, a cylinder, nothing happens. When I just translate it, the arm follows nicely.
What am I doing wrong? I properly activated the “Rotation”-part of the constraint. I know that it basically works, because I have one sample where it works. But as soon as I scale this one to real life dimensions, the rotation part of the constraint stops working properly too.
Many thanks for any help! I attach a screenshot and the Blender file.
