  Type Name Description
Public class FAnalyticImplicitGroup Copyright Epic Games, Inc. All Rights Reserved.  
Public class FCharacterGroundConstraintProxy Proxy class to manage access to and syncing of character ground constraint data between the game thread and physics thread  
Public struct FClusterUnionChildData    
Public struct FClusterUnionInitData    
Public class FClusterUnionPhysicsProxy    
Public struct FClusterUnionSyncedData Extra data that needs to be synced between the PT and GT for cluster unions.  
Public class FConstraintProxy
