Merging Create Ore Excavation with Mekanism: A Datapack Deep Dive
Minecraft modding thrives on creative crossovers, and one of the most exciting recent developments is the seamless integration of the Create mod's ore excavation system with Mekanism's resource lineup. If you have ever wanted to drill for Osmium, Uranium, or Fluorite using the satisfying mechanical contraptions from Create, a dedicated datapack now makes it effortless. This guide unpacks everything you need to know about the Create Ore Excavation x Mekanism datapack, from its ready-to-use ore veins to fine-tuning rarity for a balanced multiplayer server.
Why This Datapack Changes the Game
Create Ore Excavation lets players find infinite or finite ore veins beneath the surface, then pump them out with drills and fluid networks. Mekanism adds a whole suite of industrial ores essential for advanced factories. Normally, these two mods do not talk to each other — Mekanism ores spawn through standard world generation, while Create's excavator looks for its own vein types. This datapack bridges the gap by defining five brand-new ore veins that spawn naturally and respond to the excavator's detection mechanics. Suddenly, your mining operations can tap into Lead, Tin, Uranium, Fluorite, and Osmium without ever picking up a pickaxe again.
Key Features at a Glance
- Five Preconfigured Ore Veins: Raw Osmium, Lead, Tin, Uranium, and Fluorite are all integrated into the Create Ore Excavation framework.
- Version 1.21.x Ready: The datapack uses a clean, error-free JSON structure that loads smoothly on modern Minecraft versions.
- Infinite or Finite Veins: Adjust the default COE config to make veins either endlessly harvestable or exhaustible, matching your playstyle.
- Conflict-Free Generation: Each ore vein receives an optimized salt value, ensuring they generate cleanly without overwriting each other in the same chunk.
- Easy Rarity Tuning: Server admins can tweak spacing and separation values directly in the datapack files to control how common or rare each ore is.
Installation Made Simple
Getting the datapack up and running takes only a few steps. First, download the .zip file from the official source. For an existing world, place that .zip inside your world's datapacks/ folder and run the /reload command in-game. If you are creating a brand new world, you can add the .zip directly through the "Data Packs" tab during the world creation menu — just drag and drop it into the interface. Many players find that using a dedicated launcher streamlines this process even further. For example, the foxygame.net launcher lets you browse and install mods and datapacks right from its menu, keeping your entire modded setup organized without hunting through file directories.
Customizing Ore Rarity for Your Server
By default, the ores are set to be fairly common so they are easy to find, but server admins often want to dial things back for a longer-lasting progression. The datapack makes this painless. Open the .zip and navigate to data/createoreexcavation/ore_vein_type/. Inside, you will find individual JSON files for each ore. Under the "placement" section, two values control rarity:
- spacing: The grid size in chunks where veins can appear. A larger number means veins are farther apart.
- separation: The minimum distance in chunks between two veins of the same type. This must always be strictly smaller than the spacing value.
For instance, setting spacing to 20 and separation to 8 will spread veins across a wider area while still preventing them from clumping too close. Always double-check that separation is less than spacing, or the datapack will throw errors. After editing, save the file and reload the datapack. These changes take effect immediately, allowing you to fine-tune resource availability without restarting the server.
Compatibility and Smooth Operation
Because the datapack relies solely on Create Ore Excavation and Mekanism, it does not interfere with other worldgen mods or custom biomes. The individual salt values assigned to each ore ensure that no two veins overlap in a chunk, preventing the dreaded scenario where an excavator reports a mixed signal. The JSON structure has been validated for Minecraft 1.21.x, so you can expect zero console spam or loading failures. If you ever need to remove the datapack, simply delete the .zip from the datapacks folder and run /reload — any existing veins will remain until the chunks are regenerated, but no new ones will spawn.
Why This Combo Feels So Right
Create and Mekanism share a philosophy of rewarding clever engineering over mindless grinding. By linking the two, this datapack lets you build sprawling drilling rigs that feed directly into Mekanism's ore processing chains. Imagine a contraption that bores into an infinite Uranium vein, crushes the raw ore with Create's crushing wheels, then pipes the dust into a Mekanism enrichment chamber — all without touching a single block manually. The visual and mechanical synergy elevates both mods, turning resource gathering into a puzzle of logistics and automation.
Final Thoughts
The Create Ore Excavation x Mekanism datapack is a must-have for any modpack that includes both titans. It eliminates the need for supplementary worldgen tweaks and gives players immediate access to Mekanism's unique ores through Create's engaging excavation loop. Whether you are running a small private server or a large community world, the easy customization options let you dial in exactly the right balance. Download the .zip, drop it into your world, and watch your drill arrays hum with new purpose. The only thing left to decide is how big you want to build that first Osmium rig.
