Sorry about the necro but I can not find any other post about this topic and the documentation as well as the suggested solution fall flat.
The 4.17 documentation fails in 4.23 and it differs from the video as not only does the video use the chaperone but also the documentation requires a static mesh not mentioned in the above video link. If setting up the controllers and mesh under the “Scene” or “VROrigin” the controllers mesh still fail to appear or move.
Is there any better documentation for setting up controllers or using the SteamVR hands that are so easily used in Unity? I Also tried the SteamVR git with 4.24.3 and could see the hands but the functionality is severely limited compared to working with the same tool in Unity and I would really like to switch to Unreal but this a deal killer.
