Loading Phases

• EarliestPossible: As soon as possible - in other words, uplugin files are loadable from a pak file (as well as right after PlatformFile is set up in case pak files aren't used) Used for plugins needed to read files (compression formats, etc).

• PostConfigInit: Loaded before the engine is fully initialized, immediately after the config system has been initialized. Necessary only for very low-level hooks.

• PostSplashScreen: The first screen to be rendered after system splash screen.

• PreEarlyLoadingScreen: Loaded before coreUObject for setting up manual loading screens, used for our chunk patching system.

• PreLoadingScreen: Loaded before the engine is fully initialized for modules that need to hook into the loading screen before it triggers.

• PreDefault: Right before the default phase.

• Default: Loaded at the default loading point during startup (during engine init, after game modules are loaded).

• PostDefault: Right after the default phase.

  • UEdModes need to be in modules loaded PostDefault at latest so that the factories exist in time to initialise the engine.

• PostEngineInit: After the engine has been initialized.

  • Visualisers such as Spline Component Visualisers need to be loaded PostEngineInit so that the GUnrealEd pointer is valid.

• None: Do not automatically load this module.
