Calculating Offsets with InverseTransformPosition

Hello,

@Bunny83 So the weapon is attached to the right hand palm and i am using an additional sphere as the limb ik right hand effector. I want to move this sphere via script to the position so that the ads point (sight of gun) is matching the 0 x 0 y 0 z position with the camera. --> Aim Down Sights

I attached a link where you can see the photos in another thread (cause i cant upload that big pictures): https://forum.unity.com/threads/noob-question-calculating-offset-problem.679675/

My script:

  RH_HandEffector.transform.localPosition = RH_HandEffector.transform.InverseTransformPoint((Camera.transform.position -RH_HandEffector.transform.position)-(RH_HandEffector.transform.position -Sphere.transform.position));
