How to include cultures in UAT build via console?

We have multiple cultures localized that we can select and use in the editor, but when building the project via “RunUAT.bat BuildCookRun …”, only en is included. Is it possible to just pass it as some parameter? In the UnrealFrontend, you can select “cooked cultures”, but that setting does not show up anywhere in the command that is printed when starting that configuration so I can’t just copy-paste it from there.

I’d love to know this too!

we eventually found out! here is an example:

Engine/Build/BatchFiles/RunUAT.bat BuildCookRun […] -CookCultures=en-US+de-DE+ja-JP […]
