This is an addon for UltraCosmetics that automatically replaces the UltraCosmetics main menu with a custom one and requests players download a resource pack.

Configuration
By default, the plugin will request players download the resource pack when they join. If your server already has a resource pack, you can disable this behavior in the UC-GUI-addon plugin config.
You can download the resource pack directly from here: https://github.com/dennishzg/uc-gui/releases
