How to edit the Main, login screen and client resolution
Customize your server's client: edit the Main, the login image, the WTF file, the accents and the screen resolution.
The client is your server's face. Customizing the Main, login screen and resolution gives everything its own identity — but requires care, since editing the Main is sensitive.
Edit the Main
The Main controls connection, texts and client behaviors. Common edits:
- Point the connection to the server's IP/domain;
- Change texts and titles;
- Adjust behaviors supported by the season.
Login image and start screen
The login screen is a client image. Swapping it is one of the fastest, most impactful customizations — put your server's art there.
WTF file and texts
The WTF file (and client text files) hold messages and settings. Edit them to translate/adjust texts, always keeping the original format.
Accents and resolution
- Accents: fixed by adjusting the client's font/language files;
- Resolution: the client has a resolution setting; adjust for modern screens (widescreen) as the season supports.
