 Note that even though the Unreal editor labels these as overrides when creating them,
 they do not cancel the original function on the actor

 check your logs for messages in the `LogBlueprintHookingCodeGen` and `LogBlueprintHookManager` categories.
 A failure to attach a hook will produce a message and usually also the blueprint bytecode.

+=== Modify Function Arguments
+
+You can modify the arguments the hooked function receives by using a Before Hook targeting Function Entry Statement.
+Add the parameter you want to modify as a By-Ref parameter on your hook function.
+The initial value can be accessed via the parameter and modified by a Set By Ref node.
