Clockwork: Atlas
If you have ever run a modded server with airships, you already know the pain of a broken blacklist. Players figure out how to glue half the world onto a flying vessel, and suddenly your carefully balanced server turns into a lag machine. That is exactly the problem Clockwork: Atlas was built to solve. This small but mighty add-on patches the ship block blacklist configuration for Valkyrien Skies and Clockwork, giving server owners and pack developers the control they were promised in the first place.
What Clockwork: Atlas Actually Does
Valkyrien Skies lets you build fully physics-enabled ships, and Clockwork is the companion mod that ties those ships into the Create ecosystem. Both mods ship with a config file that is supposed to let you blacklist certain blocks so they cannot be placed on or assembled into a ship. In practice, that config has been unreliable, and blocks you thought were banned still end up welded to a hull.
Clockwork: Atlas fixes the original config file for that ship block blacklist. Once installed, the blacklist behaves the way it should. Any block you list is blocked from placement on a ship and from being assembled into one. That means you can finally stop players from slapping down chests full of loot, spawners, command blocks, or whatever else breaks your economy and your tick rate.
Why Server Owners Need This Add-On
Running a public Valkyrien Skies server without a working blacklist is an exercise in frustration. The moment someone builds a flying fortress out of banned blocks, you are stuck manually cleaning up the mess or rolling back chunks. Clockwork: Atlas for Minecraft removes that headache entirely.
- Prevents players from placing restricted blocks onto ships.
- Stops restricted blocks from being assembled into a vessel in the first place.
- Keeps your server's performance stable by blocking lag-heavy blocks.
- Protects your economy from exploiters hauling contraband through the sky.
- Works as a lightweight patch rather than a full overhaul.
Because it only touches the blacklist logic, it plays nicely with the rest of your modpack. You do not need to rewrite your configs from scratch, and you do not need to babysit every ship that gets built.
Supported Versions and Loaders
Clockwork: Atlas is designed for Minecraft 1.18.2 and 1.19.2, the versions where Valkyrien Skies 2 and Clockwork are most commonly deployed. It runs on Forge, which is the loader both of those mods target. If you are running a Fabric setup, you will want to double-check compatibility before adding it, since the underlying mods themselves are Forge-first. Always confirm that your Valkyrien Skies and Clockwork builds match the versions the add-on expects, because a mismatched config format is the fastest way to break the patch.
How to Install
Installation is straightforward, and you do not need to be a modding veteran to pull it off.
- Make sure Valkyrien Skies and Clockwork are already installed and working.
- Download Clockwork: Atlas and drop the jar file into your mods folder.
- Launch the game once so the config file generates properly.
- Open the config and add the block IDs you want to restrict.
- Restart the server or client and test with a quick ship build.
If you would rather skip the manual file shuffling, the foxygame.net launcher handles the whole process in a single click, and its built-in catalog keeps Clockwork: Atlas updated automatically whenever a new build lands. That means fewer version mismatches and less time digging through folders.
Configuring Your Block Blacklist
The real power here is in the config. You can blacklist anything from storage blocks to functional machines to decorative blocks that cause rendering issues. A good starting point is to ban anything that stores items, anything that spawns entities, and anything with a heavy tick cost. From there, tailor the list to your server's rules.
Keep in mind that the blacklist applies at two stages: placement and assembly. That dual check is what makes Clockwork: Atlas genuinely useful, because a player cannot sneak a banned block onto a ship by building it on the ground first and then merging the two vessels together.
Final Thoughts
Clockwork: Atlas is one of those quiet quality-of-life add-ons that you only notice when it is missing. It does not add flashy content or new machines. What it does is make an existing feature work correctly, and for anyone running airships on a multiplayer server, that is worth far more than another decorative block. If your Valkyrien Skies ships have been ignoring your blacklist, this is the fix you have been waiting for.
