This plugin introduces a much simpler method of localizing your game in Unreal Engine by simply importing a CSV file into the engine's *.locres localization files.
Great solution for smaller teams who only want to localize text and need an easy-to-use format that they can translate themselves or in a localization studio.
Import can be done via the plugin editor panel or via command line.
The plugin also allows you to switch between imported languages in the standalone game, but also when playing in the editor (PIE) and when previewing assets in the editor.
The plugin is free and open source. Any contribution and support is welcome.
