Parenting to lock view in Vive while moving object

Hi I am finishing a work and I need to have the person in the Vive headset travel down a cylinder with their view locked. If I parent the cylinder to the VR_Pawn camera it locks it how I want. But if I then BP the cylinder to move,(eg lerp it) the cylinder appears to be is un-parented while the move happens and then re-parents when it is finished. This means that the person in the Vive headset can look around and move away from the cylinder instead of travelling down it.

Is there something I can do to resolve this or another method?

Any help is really appreciated as I have a major deadline (of course!)
Thanks very much

I realised that I was using world settings instead of relative settings. All solved now!
