Hello, i found a way to make the menu completely in the german language. In that topic i write it down and hope you can understand it. In the folder: C:\Program Files (x86)\Steam\steamapps\common\rFactor 2\Bin\Bundles\ .... are all menu files. It's "*.jar" files. You can unzip it with Winrar or other programs. Please make a copy from the original file Files with "net.rfactor2.app. ..." are important for the game ui. If you open a file like "net.rfactor2.app.materialeditor.jar" you can see some folders: i18n META-INF net static Go into "META-INF" and open the folder "dependencymanager". The file "net.rfactor2.app.materialeditor.MaterialEditorApp" has a line for the language part. Open it with Notepad++ or a other one. the line for the language file: before: "net.rfactor2.i18.translation.template":"/i18n/materialeditor.pot" afterthan: "net.rfactor2.i18.translation.template":"/i18n/de_DE.po" why "de_DE.po" ? in the folder i18n are only 2 language files. english + german. and the german one has the name "de_DE". save the "net.rfactor2.app.materialeditor.MaterialEditorApp" file and if you use Winrar you can drag the file into the program. Start and hope the menu is in german. If you are interested, I can also upload the files. Note: The "de_DE.po" file has not yet been completely translated.
