Alchemy Factory Mods: Workshop Blueprints and Nexus

Alchemy Factory has two mod sources rather than one: a Steam Workshop library built around blueprints, and a Nexus Mods section built around files. They solve different problems, and the more useful question is which channel a given goal belongs to.

Two Mod Sources, Not One

The Steam Workshop page is titled Alchemy Factory Blueprints Workshop, and its description explains the intent: share blueprints, subscribe to other players' blueprints, and build the ultimate factory.

Nexus is the other half. Its Alchemy Factory section presents itself as a place to browse mods for the game, with the usual category filters - the visible category list puts Miscellaneous at 28 files.

That split is why searching for "Alchemy Factory mods" produces two different kinds of answer. One channel distributes structures to place in a save, and the other distributes files that change the game.

What the Steam Workshop Blueprints Are

The workshop items are named like factory plans. Eternal Catalyst Fix v2.2.2 is published by HayRake, alongside a Full belt Growth Potion build tagged Steam V1.2 and a Sulfuric Acid blueprint from the same author.

The other publishers follow the same pattern. KoTaM's T8_Potion Panacea is described as a one blender, steam fix, and VtMystic's Advance Compacted Stage 4 stone Factory is a compacted production block. X5-FACTORY's 2-in-1 Bandage + Healing Potion Factory combines two production lines in one build.

Reading those names is the fastest way to judge a blueprint. The version tag says which build the layout was made for, and the word "fix" says the author is correcting a layout that stopped working rather than inventing a new one.

What Nexus Carries

The Nexus side is smaller and less specialised. Its Alchemy Factory section lists a single visible category, Miscellaneous, with 28 files inside it.

That shape tells a player what to expect: there is no separate gameplay or visual category yet, so a mod that changes the game sits next to a mod that changes an item value, and browsing the whole list takes less time than filtering it.

Which Source to Use

Use the workshop when the problem is a layout. A player who cannot get a production line to run, or who wants a compact smelting block, is asking for a blueprint, and the workshop is where those are published and subscribed to.

Use Nexus when the problem is the game itself. Files that adjust values or add behaviour belong on that side, because the workshop channel is framed around blueprints rather than around code.

Either way, check the version before trusting the result. The workshop titles carry tags such as v2.2.2, and a blueprint built for an older patch can place cleanly while producing the wrong output.
