Replication Extended Registry – Data & scripting
This mod ships built-in matter value recipes (Replication) for many mods and provides an external scripting system to register or override matter values without editing the mod.
Built-in matter values (datapack)
Under data/rep_ext_reg/recipe/matter_values/items/ the mod includes matter value definitions grouped by mod. These are standard Replication replication:matter_value recipes and are loaded with the game.

Scripting system (external scripts)
Besides the built-in data, rep_ext_reg can load register scripts from a configurable folder. Those scripts are JSON files that assign matter values to items (or item tags) and are applied after Replication's calculation, so you can add or override values without changing the mod or the datapack.
- Path: Set in mod config → dev → externalScriptsPath. Default:
kubejs/external_scripts/rep_ext_reg. - Format: Each JSON file must have
"type": "rep_ext_reg", optional"aggressive"(override existing values), and an"entries"array. Each entry has:res: list of item IDs ("minecraft:tnt") and/or tags with#("#c:ingots/lead"). Multiple IDs in one entry share the same matter definition.mat: list of matter type → amount, e.g.[{"replication:earth": 10}].
- When: Scripts are loaded on server start and on
/reload; values are injected once Replication has finished its matter calculation.
When the scripts folder is created (or when the mod runs), it auto-generates a README in that folder with the full format description and examples. Create the folder, run the game once, and use the generated README.md there as reference.
