How do I translate the mod?

Please view the following wiki page: Dev:Translating the mod. Thank you so much for your contribution!


Can I create a very large ship?

Yes, you can. However the default blocks limit for a ship is 15000 blocks. You can change this value by doing /physsettings maxshipsize 15000, or going in the config, depending on the version you're using. Furthermore, there is a hard cap of ship size at 32x32 chunks.

I have many hovercraft compressors placed on my ship, but it doesn't fly?

Your problem may be one of the following:

  • Your physics engine is disabled (Right click on the physics engine to enable it).
  • Your hover crafts controller has a too low height specified or the compressors are not connected with the hover craft controller.
  • Your ship is too heavy. You need to place more hover compressors or more Valkyrium.

I have lost my ship, can I have it back?

First, try /vs ls -v to view a list of ships with coordinates. You can also use /vs tpto to teleport to a ship.

If your ship disappeared after crashing or rejoining the world, it may be incompatibility issues with other mods (See Compatibility list). If your ship disappeared due to any other issue, you should report it at the GitHub issues page.

Do boats exist yet?

Yes! While visually water is still present, you can use pumps to remove the effects of it.

Propellers wont connect to my engine! What do I do?

Do the following:

  1. Make sure your Ship is infused!
  2. Replace your Valkyrium Engine.

What are all the slots in my Physics Infuser for?

At the moment, only the middle one is used, and it must contain a Physics Core

Where are the blocks of the ship stored?

In an area colloquially known as the 'shipyard', from the coordinates X = 5119888 to X = 5120112, and Z = -112 and higher


Do blocks have weight?

Yes, and you can configure it in the config.

What units are used?

Unless otherwise noted, all units are SI units. Kilograms for mass and Newtons for force.

Common Problems

I get some kind of crash with "Mixin" and "ClassNotFoundException"?

Try adding a bunch of brackets in front of the Valkyrien Skies jar in your mod folder, like [[[[valkyrienskies.jar, in order to sort its load order to the front.
