Hello, I’m currently trying to rig a robotic arm composed of an IK for the arm, a ball joint for the “hand”, and 2 rails driving 4 hooks.
The IK is ok, the hand aim a target, the hooks get closer with a float control, same for the 2 rails. The problem is when I move and rotate the hand (with IK or with Aim), rails and hooks don’t follow. I tried to make them parent-child, invert and add transforms, etc… Nothing works.
Here’s images of the way i make rails and hooks move. Bones are attached to their floats translation so here’s why it doesn’t move with the parent.
I think it has to move in the space with the cube control and locally with the arrows but it means making the arrow move with the cube and notmaking bones move with them.
I’m not experimented with rigging nor with blueprint, i try to learn.
