The first tool is Unreal Engine, so they're working in the engine as well.

Unreal Engine has a localization dashboard, which is a place where you can add languages that you want to support.

So you can import, export text translations.

It also has a handy function to gather all the text in the entire game and put that into the localization database so that it can be translated.

And then lastly, of course, Unreal Engine needs to compile all the text translation so that it can be used in the game at runtime as well.

That's what we also need to use Unreal Engine for.
