Tired of Applied Energistics 2 autocrafting choking on byproducts? This fixes it.
Many AE2 processing patterns (ore doubling, chemical reactions, smelting chains) produce a primary output plus one or more secondary outputs ("byproducts"). In a lot of modpacks those extra outputs jam ME autocrafting: the network can't route every output to a valid place, and the craft stalls.
AE2 No Byproduct solves it at the source, and gives you a tool to clean up the patterns you've already made.
A small button sits in AE2's native left-hand toolbar (right next to AE2's own buttons):
It's per-player, server-authoritative (no client bypass), and your choice is remembered across relog, restart, and death. Crafting, smithing, and stonecutting patterns are never touched; they only have one output anyway.
Already encoded a bunch of patterns with byproducts? Don't re-do them. Craft the Byproduct Remover and shift + right-click any Pattern Provider, and every processing pattern stored inside it is instantly re-encoded to keep only its first output. You get a chat message telling you how many were cleaned.
Works on AE2's Pattern Providers and add-on providers (tested with Extended AE and MEGA Cells).
Recipe (shapeless): 16k Storage Component + Blank Pattern + Crafting Unit
Need to clean a whole base at once instead of one provider at a time? Operators can run /ae2nobyproduct strip-all while looking at any block of an AE2 network: it strips byproducts from every Pattern Provider in that network (block and cable-part forms alike). It is deliberately two-step so a bulk edit is never an accident: the first run previews how many patterns would change, and running it again on that same network within 30 seconds applies it.
A server config lets pack authors decide exactly how it behaves, including forcing byproduct removal for everyone with no per-player UI at all.
The config is created on first launch in your config/ folder like other mods: a single JSON file, config/ae2nobyproduct.json, on every loader. The options are identical on all loaders. On a multiplayer server, the server's config is the one that applies.
| Option | Default | What it does |
|---|---|---|
enableFeature |
true |
Master switch. false = the mod does nothing and shows no button. |
allowPlayerToggle |
true |
false = the button is hidden and defaultStrip is forced for everyone. |
defaultStrip |
false |
Starting value for new players; also the forced value when allowPlayerToggle = false. |
consumeOnUse |
false |
true = the Byproduct Remover is consumed after it cleans a provider. Default keeps it reusable. |
showMessages |
true |
false = silence the Byproduct Remover's chat feedback. |
Want byproducts gone pack-wide, no questions asked?
{
"allowPlayerToggle": false,
"defaultStrip": true
}The button disappears and every player's processing patterns are stripped automatically.
Server and client mod. Install AE2 No Byproduct on both the server and the client. On a dedicated or LAN server it must be present on the server and on every client that connects: the toggle button and Byproduct Remover live on the client, while stripping is enforced on the server. In single player, one copy in your
mods/folder covers both.
| Minecraft | Loader | Required: Applied Energistics 2 | Java |
|---|---|---|---|
| 1.20.1 | Forge 47.x, or Fabric (Loader 0.16+ with Fabric API) | 15.4.x | 17 |
| 1.21.1 | NeoForge 21.1.x | 19.2.x | 21 |
(AE2 requires GuideME: bundled inside AE2 on 1.20.1, and a separate mod that CurseForge and Modrinth auto-install with AE2 on 1.21.1. Either way, having AE2 covers it.)
1.21.1 is NeoForge only, because Applied Energistics 2 has no Fabric or Forge build for 1.21.1.
Pick the jar that matches your loader and Minecraft version: it is named ae2nobyproduct-<loader>-<modversion>+mc<mcversion>.jar, for example ae2nobyproduct-forge-0.2.0+mc1.20.1.jar, ae2nobyproduct-fabric-0.2.0+mc1.20.1.jar, or ae2nobyproduct-neoforge-0.2.0+mc1.21.1.jar. All loaders and versions are built from the same single codebase using the Stonecraft Gradle plugin (Stonecutter + Architectury Loom).
