I’ve found the solution if anybody runs into the same problem.
There is an article on the unrealwiki; ‘Oculus Rift Separate View’ that gives you a number of steps to follow.
You can also just get a ‘get player camara manager’ node in the EventGraph, and drag out a ‘Follow Hmd Orientation’ from that.
Setting this to true has the same effect as following all the steps in the article, and enables you to look around with the Rift while being animated by matinee.
