How to make actor follow and face camera in VR

im making basic a VR zombie shooter where the player stands in place and zombies come to him
i tried using AI move to node but the zombies keep moving behind the camera and attacking the air
which also counts as a hit

how do i make the zombies face the camera always and stand in front of it?

in my character pawn i have a scene as the root, i tried making it the camera but it doesnt work
maybe there’s something there

if you want to know how my project is set up, it is fairly close to the UE4 twin stick shooter tutorial
