Important info first

This mod MIGHT CHANGE in the future, potentially breaking old worlds in the process!

The end dimension is only supported in V3.6.0 and above. In older mod versions, the end is vanilla.

Biomes added by other mods WILL NEED A DATA PACK to generate in Big Globe worlds.

Ores, flowers, and other features and structures added by other mods WILL NEED A DATA PACK to generate in Big Globe worlds.

Data packs that provide compatibility for other mods can be found on my Discord server. The invite to my Discord server has been temporarily removed from Modrinth to prevent an influx of new users from a certain popular YouTuber. And also none of those compatibility packs have been updated in a long time anyway and probably don't work anymore, so you're not missing out on anything by not being there. EDIT: Since a lot of people have been asking for compatibility with Create specifically, I've gone ahead and released a compatibility data pack for Create here.

This mod generates worlds on a VERY LARGE scale, both horizontally and vertically. Exploration and resource collecting will be difficult.

This mod uses more RAM than vanilla due to worlds being taller. Be prepared to have to allocate a lot of RAM to the game.

This mod is NOT recommended for use on multiplayer servers, because tall chunks consume a LOT of bandwidth. If you do use it in multiplayer, expect chunks to load slowly, and difficulty connecting and staying connected.

This mod is not planned to support Forge or NeoForge, however it does work with Sinytra Connector. Just note that if you are using an older version of Big Globe than V4.5.0, you will need to disable MobSpawnerLogic_SpawnLightning inside .minecraft/config/bigglobe/mixins.properties for this to work.

Ok, now on to the description

Big Globe is, at its heart, a worldgen mod which overhauls all 3 vanilla dimensions to be bigger. Ever since Minecraft 1.18, mods and data packs have been able to change how tall worlds are, and Big Globe takes full advantage of this. The overworld in Big Globe is 2048 blocks tall, while the nether and end are both 1024 blocks tall.

But Big Globe isn't just about making worlds taller. It also provides completely custom terrain features for just about everything, AND it comes with over 100 new blocks to make the game feel more immersive. Most of them are designed to be decorational or fit in with vanilla, but some of them have their own mechanics too, to make certain parts of the game easier. You can find a full list of current blocks and items here.

Big Globe also comes with its own scripting language which data packs can use to add their own worldgen features governed by arbitrary rules. The overwhelming majority of Big Globe's terrain features are, in fact, scripts. But with great power comes great cost: most worldgen added by other mods or other data packs will have no effect in Big Globe worlds. But all is not lost! Data packs designed for Big Globe can place content from other mods or other data packs, so you can make a "compatibility" data pack to bridge the gap between how vanilla does things and how Big Globe does things.

Getting started

Once you've installed Big Globe, simply set the world type to "Big Globe" when creating a new world. If you're a server hoster, set level-type=bigglobe\:bigglobe in server.properties. Big Globe will attempt to spawn you in an area with trees to make getting started a bit easier.

Big Globe also changes where some resources generate. If you can't find something and don't know where to look for it, this link might help you.

Recommended other mods to use in combination with Big Globe

Sodium, Lithium, Ferrite Core, and Starlight/ScalableLux: recommended because Big Globe demands a lot of resources by default, and these mods can reduce that somewhat.

C2ME: recommended because it contains a number of optimizations which can improve performance while doing worldgen. Note however that Big Globe already has concurrency built-in to its chunk generator, so the multi-threading aspect of C2ME will be less effective in Big Globe worlds than in vanilla worlds.

Noisium: not recommended in Big Globe worlds because it only helps with vanilla chunk generators, and does not contain any optimizations that Big Globe doesn't already have. Noisium is still useful inside vanilla worlds, so if you plan on creating both, then Noisium is recommended.

Distant Horizons or Voxy: recommended in order to see terrain far away. This can make it easier to find areas that interest you, and make it easier to collect resources, as some resources only spawn in specific areas.

In 3.x, mods which let you teleport between locations you've already visited are recommended because worlds as large as Big Globe make transportation difficult otherwise. In 4.0 and later versions, Big Globe has this functionality built-in.

In 4.0 and later versions, Satin is recommended, because waypoints and hyperspace look cooler when Satin is installed.
