Apply rotation from translation control rig

Hey guys,

I have a question concerning the control rig. I have set up a control rig for my humanoid mesh based on the UE skeletal mesh. It’s working fine but I wanted to improve it on the arm movement. Basically I want the top part of the spine to rotate when the arm is fully stretched so that the mannequin can reach a bit further. It means that a translation of the hand (which with my current control rig, control arm) should induce a rotation of the top spine if it’s needed. Any ideas on how to achieve this ?

Thanks

No answers for 4 years. I hope that you figured it out by now. Anyway since no one answered, I’ll answer for posterity. To convert rotation into translation in control rig use the To Euler node. To convert Translation into rotation use the From Euler node.
