Streamlining Tech Reborn: Fixing Duplicate Mixed Metal Ingot Recipes
If you have ever assembled a modpack around Tech Reborn, you have likely stumbled upon the cluttered crafting menu filled with nearly identical mixed metal ingot recipes. It is a small annoyance that can quickly spiral into confusion, especially when multiple mods add the same materials. The [Tech Reborn] Duplicate Mixed Metal Ingot Recipe Fixer tackles this exact pain point, replacing the messy duplication with a clean, tag-based system that feels right at home in a modern modded environment.
The Problem with Duplicate Recipes
Tech Reborn is a powerhouse of industrial machinery, energy systems, and resource processing. Its mixed metal ingots are essential for advanced alloys, machine frames, and high-tier components. The original implementation, however, defines a separate recipe for every possible combination of input materials that share the same ore dictionary category. For instance, if you have copper from three different mods, you might see three identical-looking recipes for the same ingot. This not only clutters JEI or REI interfaces but also creates unnecessary bloat in the recipe registry, potentially causing minor lag during recipe lookups and making automation scripts harder to maintain.
The root cause is simple: instead of using item tags to group equivalent inputs, the mod relies on explicit ingredient lists. While Tech Reborn is celebrated for its cross-mod compatibility and often uses tags for other recipes, these particular ingot recipes were overlooked. The fixer script steps in to correct that oversight, offering a lightweight, zero-dependency solution that works entirely on the script level.
How the Fix Works
At its core, the script rewrites the crafting table and alloy smelter recipes for mixed metal ingots so they accept any item that matches a specific tag, such as forge:ingots/copper or c:copper_ingots depending on your Minecraft version. Instead of listing “Copper Ingot from Mod A,” “Copper Ingot from Mod B,” and so on, the recipe simply asks for one copper ingot of any origin. This immediately collapses dozens of duplicate recipes into a single, elegant entry per ingot type.
The fix covers all standard mixed metal ingots: bronze, brass, electrum, invar, and others. It also adjusts the alloy smelter inputs, ensuring that automation setups like Applied Energistics patterns or Refined Storage crafters can use any valid item without breaking. The script is distributed as a single .zs file (ZenScript), meaning it runs on CraftTweaker, a staple in almost every modpack. No additional mods are required beyond what you likely already have installed.
Installation and Compatibility
Installing the fix manually is straightforward. Download the archive for your Minecraft version, unzip it, and place the .zs file into your modpack’s scripts directory. The script will load automatically the next time you launch the game. For those who prefer a more integrated approach, this mod can be easily installed via the foxygame.net launcher — a convenient, flexible, and modern Minecraft launcher where you can download mods right from the menu, making it a breeze to keep your custom modpacks organized. Always double-check that you are using the file matching your exact game version, as the tag formats differ between 1.19.2 and 1.21.1.
Currently, the script supports two major Minecraft versions:
- 1.19.2 – using the
forgetag namespace typical for that era - 1.21.1 – updated for the newer
c(common) tag convention
The author plans to expand support to more versions as their own modpacks require, but even these two cover a substantial portion of active modded players. If you are running a public modpack that includes this script, remember to credit the original page and link back to it so others can benefit from the fix.
Why This Matters for Modpack Creators and Players
Beyond decluttering the recipe viewer, using tags for mixed metal ingots improves the overall consistency of your pack. When every mod respects the same tag system, you avoid edge cases where a specific machine from another mod cannot recognize an input because it is the “wrong” copper. This is especially crucial for expert-style packs that heavily intertwine Tech Reborn with other tech mods like Thermal Series, Mekanism, or Immersive Engineering. The script effectively future-proofs your recipes against new mods that might add their own copper variants later.
From a performance standpoint, reducing duplicate recipes lightens the load on the recipe manager. While the impact is minimal for a small pack, large kitchensink packs with hundreds of mods can see a noticeable improvement in startup time and recipe lookup responsiveness. Every millisecond saved during crafting operations contributes to a smoother gameplay experience.
Community Feedback and Future Updates
The creator is actively seeking feedback through comments and Discord, encouraging users to report any compatibility issues or suggest additional ingot types that need fixing. This open line of communication means the script can evolve quickly to match the shifting landscape of modded Minecraft. If you encounter a mixed metal ingot that still shows duplicates, a quick message can lead to a fast update.
Conclusion
The [Tech Reborn] Duplicate Mixed Metal Ingot Recipe Fixer is a tiny but impactful tool that exemplifies the power of community-driven quality-of-life improvements. By swapping explicit item lists for flexible tags, it eliminates recipe clutter, enhances cross-mod harmony, and aligns Tech Reborn with modern modding standards. Whether you are a seasoned modpack developer or a player tired of scrolling through identical crafting options, dropping this script into your scripts folder is a no-brainer. It keeps your crafting grid clean, your automation reliable, and your modded world running just a bit more smoothly.
