Getting Started with Space Engineers Modding

Workshop subscriptions, world mod-set, Programmable Block scripts, and multiplayer

Space Engineers modding is Workshop-driven, officially supported, and clean. Subscribe via Workshop, activate per save, play. This guide walks the standard install.

SE Workshop hosts thousands of mods. Browse:

Blocks: new ship and base building blocks.
Scripts: Programmable Block C# scripts for automation.
Mods: gameplay logic mods.
Skins / blueprints / worlds: cosmetic and starter content.

Subscribe to any. SE downloads on launch.

Step 2: Activate for a world

When starting (or loading) a save:

Mods tab on the world setup screen.
Move subscribed mods from Available to Active.
Set load order (drag).

Each world remembers its mod set.

Step 3: Recommended first picks

Build Info / Build Vision: extensive UI info during construction.
Catwalk Building Pack: additional structural blocks.
Industrial Overhaul or Whip's mods: quality-of-life script mods.

Step 4: Programmable Block scripts

A separate sub-scene. Programmable Block is an in-game object that runs player-written C# code. Workshop hosts thousands of community scripts:

Whip's Auto Door Mod: door automation.
Easy Inventory Manager: ship-wide inventory sorting.
Fleet AI scripts: autonomous mining and combat.

Scripts are pasted into a Programmable Block's editor in-game. They don't need Workshop subscription if you have the code; Workshop is just a convenient distribution channel.

Step 5: Multiplayer

Server's mod list is canonical. Clients auto-subscribe to the server's mods on join.

For dedicated servers: configure mods in the server's settings file plus Steam Workshop collection.

Common gotchas

Mod compatibility with current SE version. Workshop shows update dates; mods more than a year old may not work with current SE.
Performance dropped with mods. Physics-heavy block mods are the usual culprit.
Script doesn't compile. SE's compiler is strict. The error appears in-game; read it.
Multiplayer can't auto-download mod. Workshop sync issue. Manually subscribe before connecting.

Space Engineers' modding scene rewards engineering-minded play. The C# scripting layer especially is unusual for a sandbox game, and uniquely powerful.
