Free downloads in the Crucible launcher
The Crucible launcher hands out free Rust map assets: a finished map, server plugins, custom prefabs and a guide. Open the Shop and pick the Maps, Plugins, Prefabs or Extras tab. There is no account, no purchase and no key, and you choose where each file saves.
Crucible Volcanic 3800
Section titled “Crucible Volcanic 3800”
A volcanic map Drizzza made with Crucible Heightmap, free to use, so you can see for yourself what a full map looks like. Run it as it is on your server, or open it in RustEdit and pull it apart. The Crucible Heightmap project is included, so you can open the terrain it came from.
Where: Shop, then Maps.
What you need:
- The Crucible launcher
- RustEdit to open and edit the map
- The RustEdit extension on your server so the map loads
Plugins
Section titled “Plugins”Excavator Arm Fix
Section titled “Excavator Arm Fix”By bmgjet.

Move or rotate the Giant Excavator on your map and its arm ends up in the wrong place, pointing away from the pit. This puts it back. Run it on your server and the arm corrects itself. By bmgjet, shipped unchanged.
Where: Shop, then Plugins.
What you need:
- The Crucible launcher
- Carbon or Oxide on your server
Map Door Anti-Spam
Section titled “Map Door Anti-Spam”
Two fixes for doors placed in RustEdit. Spamming one no longer cancels its animation, and the invisible wall beside a closed door is gone. It only touches doors placed on the map. Player built doors are left alone.
Where: Shop, then Plugins.
What you need:
- The Crucible launcher
- Carbon or Oxide on your server
Prefabs
Section titled “Prefabs”Each prefab downloads as a zip with the prefab file and its image together. Extract both into your RustEdit CustomPrefabs folder and place it like any other prefab. Each one needs the Crucible launcher, RustEdit, and the RustEdit extension on your server so custom prefabs load. Find them under Shop, then Prefabs.
Combined Outpost
Section titled “Combined Outpost”
The Bandit Camp vendors combined into Outpost, so it is all one stop. Useful when you want the trading in one safe zone instead of two monuments eating map space.
Airwolf Camp
Section titled “Airwolf Camp”
A custom monument for the Airwolf helicopter vendor, with loot crates and a safe zone. Put one anywhere you want players buying a minicopter.
Fishing Village Marketplace
Section titled “Fishing Village Marketplace”
The drone marketplace on wooden decking. Built to sit on a fishing village, but it goes anywhere.
Guides
Section titled “Guides”Crucible x RustEdit Workflow Cheatsheet
Section titled “Crucible x RustEdit Workflow Cheatsheet”
Every step of a full custom map, in the order that works, from terrain through cargo, monuments, tunnels, roads, rail and proc gen. It comes in four screen sizes so it sits beside RustEdit and stays readable.
Where: Shop, then Extras.
What you need: the Crucible launcher.
You can also read it in the browser: the RustEdit workflow cheatsheet.
Questions
Section titled “Questions”How do I fix the excavator arm facing the wrong way?
Section titled “How do I fix the excavator arm facing the wrong way?”Move or rotate the Giant Excavator on a custom map and its arm ends up in the wrong place. Run the Excavator Arm Fix by bmgjet on your server and it corrects itself. It needs Carbon or Oxide.
Why can players walk into an invisible wall beside a closed door on my map?
Section titled “Why can players walk into an invisible wall beside a closed door on my map?”A door placed in RustEdit keeps the pose the prefab was built in, because the server never animates it. Map Door Anti-Spam poses it properly, and also stops the door being spam clicked to cancel its animation. It only touches doors placed on the map, never player built ones.
Are these really free?
Section titled “Are these really free?”Yes. No account, no purchase, no key. They are handed out through the Crucible launcher.
How do I install a custom prefab in RustEdit?
Section titled “How do I install a custom prefab in RustEdit?”Each prefab downloads as a zip holding the prefab file and the image that travels with it. Extract both into your RustEdit CustomPrefabs folder, then place it from the custom prefab list like any other.
Do I need Crucible Heightmap to use these?
Section titled “Do I need Crucible Heightmap to use these?”No. The prefabs, the plugins, the map and the cheatsheet all stand on their own. Crucible Heightmap is the paid terrain generator and it is separate.
Can I use these on my own server?
Section titled “Can I use these on my own server?”Yes, community servers included. The plugins need Carbon or Oxide. A map that uses custom prefabs also needs the RustEdit extension on the server so its custom data loads, which the Crucible Local Server installs for you.
