Theurgy Reformation Clean Output

Theurgy Reformation Clean Output is a small NeoForge compatibility addon for Minecraft 1.21.1 that fixes a specific output-cleanliness issue in Theurgy’s Reformation system.

What does it do?

In Theurgy, Reformation recipes use a target item placed on the target pedestal. By default, Theurgy can copy data/components from the target item onto the produced result.

This can cause problems in automation setups, especially when using Applied Energistics 2 Processing Patterns, Pattern Providers, and external automation tools such as Super Factory Manager.

For example, if a renamed sulfur item is used as a target seed:

Input target: [SEED] Diamond Sulfur
Expected output: normal Diamond Sulfur

Theurgy may output another [SEED] Diamond Sulfur instead of a clean normal sulfur. In some cases, target-specific data such as custom names, repair cost, or unique serialized component data can also be copied to the result. This can prevent the output from stacking correctly and may cause AE2 crafting jobs to remain incomplete.

This addon changes Reformation output behavior so that the produced result uses the recipe’s clean result stack instead of inheriting target-specific copied data.

Why was this made?

This mod was created to make Theurgy Reformation easier to automate with AE2.

AE2 struggles with processing patterns where the exact same item stack is both an input and an output. A common workaround is to use a renamed target sulfur as a reusable “seed” input while expecting the clean sulfur as the output.

However, Theurgy’s default target-data copying caused the renamed seed data to appear on the output as well, breaking that workaround.

This addon allows setups like:

Input:

1x renamed [SEED] Diamond Sulfur
required Reformation source materials

Output:

1x clean normal Diamond Sulfur

This makes the output stack properly and allows AE2 automation setups to complete more reliably.

Features

Fixes copied target data on Theurgy Reformation outputs.
Prevents renamed target sulfur data from appearing on produced sulfur.
Helps outputs stack correctly.
Improves compatibility with AE2 Processing Pattern automation.
Does not add new items, blocks, recipes, or machines.
Does not modify AE2 directly.
Only patches Theurgy’s Reformation result behavior.

Compatibility

Built and tested with:

Minecraft: 1.21.1
Mod Loader: NeoForge
Theurgy: 1.21.1-neoforge-1.73.1

This addon depends on Theurgy.

Other Theurgy 1.21.1 versions may work as long as the internal ReformationRecipe structure remains compatible. If Theurgy changes its Reformation recipe class, method signature, or result field in a future update, this addon may require an update.

Technical note

This mod patches Theurgy’s ReformationRecipe output behavior. Instead of returning the result stack after target components have been copied onto it, the addon returns the recipe’s clean result stack. This prevents target-specific display data, repair cost, serial-like component data, and other copied target data from being transferred to the output.

Recommended use case

Use this addon if you automate Theurgy Reformation with:

Applied Energistics 2
AE2 Processing Patterns
AE2 Pattern Providers
Super Factory Manager or similar automation tools

Especially useful when using renamed target sulfur items as reusable AE2 seed inputs.
