Roughly Enough IDs is a fork of JustEnoughIDs to maintain compatibility for additional mods.

Roughly Enough IDs is a lightweight mod that removes the block, item, biome, potion, and enchantment ID limits by using the 1.13 chunk format in 1.12.

More specifically, it uses a blockstate palette when saving chunks to NBT, and uses an int biome array rather than a byte biome array. There should be very few incompatibilities with other mods, but in case you find one, please report it to the issue tracker.

Unlike NotEnoughIDs, removing a mod from your modpack is supported, and won‘t cause corruption of the worlds created with that mod.

Extremely important: Removing Roughly Enough IDs will break your world!

Note: Tools such as World Painter will likely not work with REID worlds should they attempt to alter biomes.

Currently supporting:

(since 2.2.0) Compatibility with Biome Staff, Kathairis, Scape and Run: Parasites, WorldEdit, Wyrms of Nyrus
(since 2.0.8) Compatibility with CubicChunks (1.12.2-0.0.1271.0). REID now requires MixinBooter.
(since 2.0.6) Partial compatibility with Astral Sorcery. Rewrites MixinEnchantmentHelper to avoid using @Overwrites to offer better compatibility with other coremods.
(since 2.0.5) Compatibility with worlds created with NotEnoughIDs. Worlds will be converted and NotEnoughIDs is no longer required.
(since 2.0.3) Compatibility with Realistic Terrain Generation Unofficial.
(since 2.0.2) Compatibility with CubicChunks (1.12.2-0.0.1208.0). Allowing you to have both infinitely tall worlds, & infinitely large Item, block & biome IDs!
(since 2.0.0) Compatibility with certain builds of The Twilight Forest.

Roughly Enough IDs should work perfectly fine in place of JustEnoughIDs. However, due to the nature of it being a fork, issues that are not present in JEID might occur in REID.
