How do i add a pitch offset to my hands?

I have a problem adding a pitch offset to my VR hands when i hold a gun. Can’t get my head around the math involved, and for some reason, i can’t post pictures on the forums right now (Says database error), so i did it on the answerhub, here:

Hope someone can assist me with the math on it.

And btw, it’s for the fullbody setup im working on here, which i’ll post a set of videos of how i built later on:


I found a workable solution to it. See below:


Right now hardcoded, but will ofc, only transform rotation if i need to. Soon i’ll start posting the tutorials for this.
