OVR CanvasWithDebug does not transfer purple line render from Locomotion sample scene to new scene

Hello,

In the OVR Locomotion Sample scene, one has the option to press a button to bring up a VR UI menu in which you can select how you want to "locomote" around the world: with static teleport points, or teleport anywhere in the scene for example. After bringing up the UI menu, you can select which locomotion option you want to use because a purple line is shot out from your controller.

I have copied these prefabs from this locomotion sample scene and into my own Unity project. I can bring up the UI locomotion option in the same way, however I am unable to select an option, because the purple line does not shoot out from my controller.

I have compared the scenes side by side, but I am still not sure why this aspect would be missing. I am new the programming, so sorting through the scripts hasn't helped me.

Thank you for any ideas!
