Currently, Battlemetrics doesn’t allow for non-EAC servers on Rust to be connected with RCON. Carbon Client is a modding platform similar to server sided modding (Yes they have a server modding framework too) but instead is made for the client. This unlocks the ability to do relatively anything you couldn’t do on the server side of things for modding. Although currently in it’s early stages of development, it would be great to get early on support for when the full thing gets released.
Support doesn’t have to include all non-EAC servers but perhaps this could be worked with the Carbon devs to allow for communication between BM servers and the Carbon framework to determine if the server is running Carbon Client.
