AE2 No Byproduct

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.

✨ What You Get

🔘 A toggle in the Pattern Encoding Terminal

A small button sits in AE2's native left-hand toolbar (right next to AE2's own buttons):

• Green check = ON: when you encode a processing pattern, only the first output is kept; all byproducts are dropped before the pattern is saved.
• Red cross = OFF: patterns encode normally, with every output.

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.

🧹 The Byproduct Remover tool

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

⚙️ Full operator / pack-maker control

A server config lets pack authors decide exactly how it behaves, including forcing byproduct removal for everyone with no per-player UI at all.

🛠️ Configuration

The config is created on first launch in your config/ folder like other mods: config/ae2nobyproduct.toml on Forge, config/ae2nobyproduct.json on Fabric. The options are identical on both loaders. On a multiplayer server, the server's config is the one that applies.

Want byproducts gone pack-wide, no questions asked?

allowPlayerToggle = false
defaultStrip = true

The button disappears and every player's processing patterns are stripped automatically.

🧩 Compatibility

• AE2 add-ons: any terminal that reuses AE2's Pattern Encoding Terminal (such as wireless pattern terminals) gets the toggle automatically. The Byproduct Remover works on add-on Pattern Providers too.
• KubeJS: the Byproduct Remover's recipe is a standard shapeless recipe, so packs can freely change or remove it with KubeJS.
• Plays nicely alongside other AE2 add-ons; it only touches the encoding step.

📦 Requirements

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.

(AE2 already depends on GuideME, so if you have AE2, you're set.)

Pick the jar that matches your loader: ae2nobyproduct-forge-1.20.1-x.y.z.jar for Forge, ae2nobyproduct-fabric-1.20.1-x.y.z.jar for Fabric.

On the roadmap: 1.21.1 (NeoForge), built from the same single codebase. 1.21.1 will be NeoForge only, because Applied Energistics 2 has no Fabric build for 1.21.1.
