Due to the textures for the chests/barrels and such, this mod is required on the server and client. Have you considered enabling a version that wouldn't require it to be installed on the client?

In that same thought process... would you consider ever releasing a plugin version of this? I can speak with personal experience that there are no good alternatives for this mod in a plugin form. I run both fabric and paper servers, and I love this mod. Just a thought for you.

Actually, it's required on both the server and the client because it introduces new blocks and new block entities into the game. The textures are simply part of that product; it would be possible to have a purely server-side version, but it would require a complete re-work of the codebase.

I've no experience writing plug-ins and unfortunately don't have the time to devote to learning it; I will say that the issues I experienced when first implementing it (in my attempts to keep it server-side) would still have to be surmounted when it comes to plug-ins and other plug-in/mod interactions.

As a curiosity, I adapted Lootr to run entirely server-side using Polymer: https://github.com/unilock/PolyLootr
