How to manage relative rotation of a child (Images)

Hi All,

I think this will be easy for the the people here!.

I have a find look at rotation targeting a Rinterp to that sets the new relative rotation.

As this object is a child from another, i cant use world rotation because it mess up. The problem i am having is that when the main object rotates it dosnt reflect that rotation in the child…so the blueprint thinks that the child didnt rotate and dont refresh in a proper way the x axie to target the find look at rotation. I tried using world rotation for the Rinterp To and then setting relative rotation and viceversa…but dont get any luck…Images below.

pd: the systm didnt allow me to upload two more photos with the blueprint.i will keep trying…THANKS!!!
