Welcome to Techno Hell

You have 5 in game days to prepare. After this the mobs will be able to break almost any block in the game the only exceptions being obsidian and netherite.

Performance

There are lots of mods here. So the modpcak is pretty demanding to run.

As you can see from some of the screenshots below then render distance looks pretty high (thanks to Distant Horizons). This doesnt affect performance for the most part, but it does increase ram ussage. I'd reccoment a minimum of 4 Gigs if you disable Distant Horizons and 6 Gigs if you leave it on (the default).

Compatibility

I plan to keep worlds compatible atleast when moving up in versions so you should be relatively safe to play the same world when upgrading modpack versions.

Downloading and running the modpack

Just download the zip file for the version you want and load it into polymc, multimc or whatever client you want to use that is capable of downloading modpacks and launch it.

Running a server

There are server files provided alongside every version in the form of Dockerfiles. Building and running a server with Docker is probably the easiest way to run a server, but it's understandable if you're unfamiliar with it that you'd want to run the server another way. It is doable the files for aquiring the mods are in the download, but it will take more work on your part. More guidance on this can be found in the ReadMe.txt file included with the server download. The server has an included web map (thanks to Dynmap). You can access that by going to serverip:8123 in a web browser.
