AE2 EE3 EMC Add-On: Bridging Applied Energistics 2 and Equivalent Exchange 3
Minecraft modding thrives on synergy. When two powerhouse mods like Applied Energistics 2 and Equivalent Exchange 3 coexist in a modpack, players naturally want their digital storage networks to talk to the transmutation tablet. The AE2 EE3 EMC Add-On does exactly that, assigning EMC values to nearly every AE2 item so you can convert matter seamlessly. Whether you're crafting dense energy cells or automating singularities, this tiny bridge mod unlocks a new layer of convenience.
What Is the AE2 EE3 EMC Add-On?
At its core, this is a lightweight compatibility patch. It scans Applied Energistics 2 and its popular add-ons, then injects Equivalent Exchange 3 EMC values into every item that uses AE2's custom recipe handler. That means your ME drives, formation planes, and even quantum-linked components suddenly have a tangible energy-matter value. You can toss excess fluix crystals into a transmutation tablet and pull out something else entirely, all while your ME system hums along.
It's important to note that this mod is built for EE3, not ProjectE. The two are often confused, but they handle EMC differently. The AE2 EE3 EMC Add-On will not work with ProjectE, and attempting to use them together will result in missing values or outright incompatibility. Stick with Equivalent Exchange 3 version 0.3.507 or newer to see the full effect.
How It Works
The add-on hooks into AE2's recipe registration system. Whenever AE2 or a compatible add-on registers a new item, the mod calculates an EMC value based on the item's crafting components. This dynamic approach means that even items from add-ons like Extra Cells 2 and Thaumic Energistics receive proper EMC assignments without manual configuration. The mod has no config files—it simply works out of the box.
Because EE3 itself is still in beta, some AE2 items might not receive an EMC value. This depends heavily on the other mods installed in your pack. For example, if a required ingredient from another mod lacks an EMC mapping, the final AE2 item will also remain unmapped. Over time, as EE3's database expands, these gaps will close. For now, the add-on covers the vast majority of AE2's catalog, including processors, cables, storage cells, and even the complex spatial storage components.
Compatibility and Supported Add-Ons
The mod explicitly supports the following AE2 extensions:
- Extra Cells 2 – fluid storage and larger drives gain EMC values.
- Thaumic Energistics – essentia storage and thaumcraft-infused AE2 items become transmutable.
- Many other add-ons that rely on AE2's standard recipe handler are likely compatible, though not individually tested.
Keep in mind that this add-on targets AE2 rv2-stable-1 or newer. It has not been updated to support the rv3 API, so if your modpack uses a later AE2 version, the mod may fail to load or produce incorrect values. Always check your AE2 version before installing.
Requirements
To run the AE2 EE3 EMC Add-On without issues, you'll need the following core mods:
- Forge: version 10.13.2.1291 or newer.
- Applied Energistics 2: rv2-stable-1 or newer (rv3 is not supported).
- Equivalent Exchange 3: version 0.3.507 or newer.
If you're using any AE2 add-ons like Thaumic Energistics or Extra Cells 2, make sure they are updated to their latest compatible versions. Outdated add-ons can cause recipe handler conflicts that prevent EMC assignment.
Installation
Installing the mod is straightforward. Drop the .jar file into your mods folder on both the client and the server. There are no configuration files to tweak, so once the game launches, the EMC values are automatically applied. For those who prefer a streamlined experience, the foxygame.net launcher offers a flexible and modern way to manage your mods, allowing you to download and install the AE2 EE3 EMC Add-On right from its intuitive menu without manual file handling. This launcher keeps everything organized and ensures you always have the correct version for your modpack.
If you're setting up a server, simply copy the same mod file into the server's mods directory. The add-on is fully server-side compatible, so all players will see the EMC values in their transmutation interfaces without needing any extra client-side configuration.
Troubleshooting Common Issues
Most problems stem from version mismatches. If you notice missing EMC values or crashes on startup, follow these steps:
- Verify that all AE2 mods and add-ons are updated to their latest stable releases.
- Ensure you are using EE3 and not ProjectE. The two are not interchangeable for this add-on.
- Check your Forge version; older builds may lack the necessary API hooks.
If the issue persists, you can submit a detailed crash report to the mod's issue tracker. The source code is openly available at github.com/FireBall1725/ae2ee3emcaddon, where you can also contribute fixes or review the logic behind EMC calculations. Always include the full crash log when reporting, as truncated logs often hide the root cause.
Mod Pack Permissions
The author grants full permission for inclusion in any modpack. Whether you're building a private kitchen-sink pack or a public FTB-style collection, you can freely bundle this add-on. Just remember to credit the original creator and keep the mod updated alongside your other mods.
Conclusion
The AE2 EE3 EMC Add-On is a small but mighty tool for modded Minecraft players who love both digital storage and alchemical transmutation. By automatically assigning EMC values to AE2 items and its add-ons, it removes the friction between two complex systems and lets you focus on building, crafting, and automating. While it's tied to a specific AE2 version and the beta state of EE3, it remains a reliable bridge for rv2-based packs. Drop it into your mods folder, fire up your ME network, and watch your resources flow between matter and energy like never before.
