+DirectoriesToNeverCook=(Path="/Game/Developers")
+DirectoriesToNeverCook=(Path="/Game/HNMain/Blueprints/Prototypes")
+DirectoriesToNeverCook=(Path="/Game/HNMain/Blueprints/Debug")
+DirectoriesToNeverCook=(Path="/Game/HNMain/Blueprints/Tests")
+DirectoriesToNeverCook=(Path="/Game/HNMain/Blueprints/World/Unused")
+DirectoriesToNeverCook=(Path="/Game/HNMain/UI/Widgets/CheatMenu")
+DirectoriesToNeverCook=(Path="/Game/HNMain/UI/Widgets/Progression")
+DirectoriesToNeverCook=(Path="/Game/HNMain/Cinematics/Prototypes")
+DirectoriesToNeverCook=(Path="/Game/HNMain/Maps/Debug")
+DirectoriesToNeverCook=(Path="/Game/HNMain/Maps/RavenBrooks/RavenB_UNMERG_Backup")
+DirectoriesToNeverCook=(Path="/Game/HNMain/Maps/RavenBrooks/RavenBrooks_Sublevels")
+DirectoriesToNeverCook=(Path="/Game/HNMain/Maps/RavenBrooks/RavenBrooks_Sublevels_New_Graybox")
+DirectoriesToNeverCook=(Path="/Game/HNMain/Maps/RavenBrooks/Sublevels")
+DirectoriesToNeverCook=(Path="/Game/HNMain/Maps/RavenBrooks/RavenBrooks_Sublevels_New/Debug")
+DirectoriesToNeverCook=(Path="/Game/HNMain/Maps/TestMaps")
+DirectoriesToNeverCook=(Path="/Game/HNMain/Geometry/Grayboxes")
+DirectoriesToNeverCook=(Path="/Game/HNMain/Maps/Act2")
so you can clear these directories (exclude developers) and leave this interesting thing as a easter egg like "/Game/HNMain/UI/Widgets/CheatMenu". but you still can never cook spoilers.
(btw never to cook means that this folder or content not in project)
and for people that saying "this is probably gonna be spoilers" they can set to never to cook these directories
