Possible to derive rotation from HMD to trigger rootmotion rotation?

Hi there, noob question here. I just recently recieved my vive and trying to learn how to use it in ue4. So like when we have a true firstperson setup, where the body can be seen if u look down urself. So i want to derive the rotation of the hmd and use that to trigger a rotationanimation using rootmotion. How would i do that? Anyone know of examples or pieces of code to demonstrate this? And is it possible to do only in BP or need some c++ modifications?

I will post an example of what i have runing as i get home. Maybe someone can suggest what to do instead. Also i would like to drive animation blendspace from movement of the hmd. Hoping someone else also has an example of this to share?
