Developer Settings

User Game Developer Settings

See UGameUserSettings.

Per Editor User Developer Settings

Thanks for Northstar for the example.

UCLASS(Config = EditorPerProjectUserSettings, DefaultConfig) class UMyFrameworkLocalDevSettings : public UDeveloperSettings

This will go into Editor preferences and write to DefaultEditorPerProjectUserSettings.ini in Saved/ which shouldn’t be committed

Plugin Developer Settings

Override GetCategoryName and return Plugins. If your class is an Editor module it will appear in the Editor Preferences and Project Settings

In the UCLASS macro, specify a correct Config value

Miscs

Custom category

To have a custom Config/DefaultMyCustomCategory you can do UCLASS(Config=MyCustomCategory, defaultconfig).

To make the custom category name in the editor/project settings, override CategoryName in the developer settings constructor.

Saving Developer Settings manually

If you are editing the CDO using a mutable ptr, you must use TryUpdateDefaultConfigFile() to write to .ini file. This works for Developer Settings classes with defaultconfig in the UCLASS
