< Unique ID for portals. This ID type exists in the same ID-space as game object ID's. The client is responsible for not choosing portal ID's that conflict with registered game objects' ID's. Internally, the spatial audio rooms and portals API manages registration and un-registration of game objects that represent portals using AkPortalID's provided by the client; AkPortalID's are convertied to AkGameObjectID's by calling AsGameObjectID().
