EndlessIDs: The Ultimate Solution for Expanding Minecraft's ID Limits
Minecraft modding has always been about pushing boundaries, but one of the most frustrating limitations has always been the hardcoded ID caps for blocks, items, biomes, and more. If you've ever tried to build a massive modpack only to crash into the dreaded "maximum ID range exceeded" error, you know the pain. EndlessIDs steps in as the unofficial successor to the classic NotEnoughIDs, taking the concept further than ever before with a focus on stability, compatibility, and truly massive new limits.
What Exactly Is EndlessIDs?
EndlessIDs is a core utility mod designed to shatter the vanilla ID constraints that have plagued large modpacks for years. While NotEnoughIDs originally raised the block ID cap from 4,096 to 32,000, EndlessIDs blows those numbers out of the water, extending both block and item IDs to a staggering 16,777,216. It also dramatically increases limits for biomes, entities, potions, enchantments, and DataWatchers, making it the go-to choice for ambitious modpack creators.
Unlike some older solutions, EndlessIDs isn't just a quick patch. It actively works to maintain world compatibility with NotEnoughIDs saves, so you can upgrade existing worlds without losing progress. If you encounter any hiccups during that transition, the developer encourages opening an issue on the project's repository, ensuring continuous improvement.
Key Features That Set EndlessIDs Apart
- Seamless NEID world upgrade: Open and convert worlds originally created with NotEnoughIDs (both the original and unofficial versions) with no extra steps.
- Expanded ID ranges: See the comparison table below — the numbers speak for themselves.
- Extensive mod compatibility patches: Built-in fixes for dozens of popular mods to prevent crashes when IDs go beyond vanilla limits.
- Required dependency awareness: The mod clearly lists its hard dependencies — FalsePatternLib, UniMixins, and ChunkAPI — so you know exactly what to install.
- Proactive crash handling: For biome ID issues with custom world generators, EndlessIDs replaces a risky vanilla method with an instant crash that points users to the GitHub repo, preventing silent world corruption.
Breaking the Limits: A Quick Comparison
To understand just how transformative EndlessIDs is, take a look at the ID caps across different versions:
- Block IDs: Vanilla 4,096 / NotEnoughIDs 32,000 / NEID Unofficial 65,536 / EndlessIDs 16,777,216
- Block Metadata: Vanilla 16 / NotEnoughIDs 16 / NEID Unofficial 65,536 / EndlessIDs 65,536
- Item IDs: Vanilla 32,000 / NotEnoughIDs 32,000 / NEID Unofficial 65,536 / EndlessIDs 16,777,216
- Biome IDs: Vanilla 256 / NotEnoughIDs 256 / NEID Unofficial 256 / EndlessIDs 65,536
- Entity IDs: Vanilla 256 / NotEnoughIDs 256 / NEID Unofficial 256 / EndlessIDs 32,768
- Potion IDs: Vanilla 32 / NotEnoughIDs 32 / NEID Unofficial 32 / EndlessIDs 65,536
- Enchantment IDs: Vanilla 256 / NotEnoughIDs 256 / NEID Unofficial 256 / EndlessIDs 32,768
- DataWatcher IDs: Vanilla 32 / NotEnoughIDs 127 (Broken) / NEID Unofficial 127 (Broken) / EndlessIDs 65,536
- Dimension IDs: Theoretically unlimited (practically 4,294,967,295) — unchanged across all versions.
These numbers mean you can now safely combine hundreds of content-heavy mods without worrying about ID conflicts. The DataWatcher fix alone is a game-changer, as older attempts to raise that limit were notoriously unstable.
Mod Compatibility: Patches for a Smoother Experience
One of the biggest headaches with ID extenders is that many mods simply aren't coded to handle IDs beyond the vanilla 4,096 block limit. EndlessIDs tackles this head-on by including dedicated compatibility patches for a long list of popular mods. Some of the heavy hitters that receive special treatment include:
- Biomes O' Plenty
- Twilight Forest
- Thaumcraft
- BuildCraft
- GalactiCraft
- Advanced Rocketry
- Witchery
- WorldEdit
- Underground Biomes Constructs
- AbyssalCraft
- Erebus
- And many more (the full list includes over 40 mods)
If a mod isn't on that list, it may still work fine, but the general rule is that the more invasive a mod is (especially those that alter world generation or core mechanics), the higher the chance it will need a patch once IDs exceed 4096 and 32000. For biome IDs, any mod that adds a custom world generator might trigger a crash by design — EndlessIDs replaces the old vanilla method to protect your world from corruption, then points you to the GitHub repository so you can report the incompatibility.
Getting this mod into your setup is straightforward. If you're using a modern launcher, the process is even simpler. For instance, the foxygame.net launcher offers a convenient way to manage your Minecraft experience: you can browse and install EndlessIDs directly from its built-in mod menu, alongside its required dependencies, without ever leaving the interface. This kind of flexibility makes assembling a stable, high-limit modpack far less daunting.
Installing EndlessIDs: What You Need to Know
Before you jump in, make sure you have the three required dependency mods installed:
- FalsePatternLib
- UniMixins
- ChunkAPI
Place EndlessIDs in your mods folder along with these, and you're good to go. If you're migrating from NotEnoughIDs, simply replace the old mod with EndlessIDs and load your world — it will automatically handle the upgrade. Should any issues arise, the mod's issue tracker is the place to report them, and the developer actively works on fixes.
Why EndlessIDs Matters for the Future of Modded Minecraft
As modpacks grow larger and more ambitious, the old ID limits have become a relic that holds back creativity. EndlessIDs doesn't just extend numbers; it provides a stable, well-maintained foundation that respects existing worlds and actively patches popular mods. Whether you're building a kitchen-sink pack with 300+ mods or a focused thematic adventure, this utility ensures that ID conflicts won't be the reason your game crashes on startup.
The jump to 16.7 million block and item IDs, combined with expanded biome, entity, and enchantment caps, means that for the first time, the ID ceiling is practically unreachable. Coupled with its smart crash handling and open development approach, EndlessIDs is quickly becoming an essential tool for any serious modpack creator. So if you've ever been limited by those tiny vanilla numbers, it's time to leave them behind and embrace a truly endless world of possibilities.
