Use of Custom Payloads in Unreal

Can you explain how I can take advantage of Custom Payloads in Unreal? If I understand it correctly, these trigger callbacks with the payload string that I can access in my engine so I can do some custom things when the event is triggered in game. I know how to add custom payloads to events in FaceFX Studio but I'm not sure how to leverage them in code. Thanks!


The Unreal Engine 4 integration does not support custom payloads. Payloads are a feature of our Legacy FxSDK and the UE4 integration uses our more optimized FaceFX Runtime.
