In OVR Platform 1.7 I see that Oculus has provided their own UE4 plugin, so you can use that as an example. If you’d rather not dabble in C++, there’s a a VerifyEntitlement blueprint function that you can use. It will asynchronously report entitlement success or failure via events. I haven’t used it myself, since I had already written our own entitlement check in C++, but you can give it a try.
