Was the issue the part of the level blueprint that gets the camera feed? I apologize but that is hardwired so you need to open up the camera feed manually, copy/paste the URL into the blueprint and the track number for the feed you want to use. I haven’t figured out how to do this automatically yet.
You may want to get more than 1 vive tracker, you will use one for the camera and will need a second one if you want to track an object, though if you have a full vive setup, you should also be able to bind objects to the VIVE controllers, though I haven’t tried this.
When you are happy with how your project works, please consider posting it to Github or at least telling us here about any new things you have learned!
