Frequently asked questions

How do I turn a structure into a ship?
Build your ship structure out of blocks, then use the mod's assembly tool to select and activate it—the structure will become a physics-enabled vessel you can control and steer.
What blocks work best for building ships?
Solid blocks like wood, stone, and metal work reliably; avoid using only transparent or partial blocks as your main hull, since the physics engine needs solid geometry to calculate buoyancy and weight properly.
Why is my ship sinking instead of floating?
Check that your hull is sealed (no gaps below the waterline) and that you have enough buoyant block volume relative to your ship's total mass—add more solid blocks or reduce heavy materials if needed.
Can I make an airship that actually flies?
Yes, use lighter block types and configure your vessel for flight mode; the mod applies lift physics to keep it aloft, though you'll need proper weight distribution to maintain stable flight.
How do I control my ship once it's assembled?
Stand on your ship and use standard movement controls (WASD) to steer; the mod translates your input into smooth rotation and forward/backward motion based on the ship's physics.
Does this mod work with shaders?
Yes, Vessel Kinetic Mod supports modern shader packs like Iris, so you can use your favorite visual enhancements while piloting ships.
What's the difference between a boat and an airship in this mod?
Boats use water buoyancy to float on the surface, while airships are configured to generate lift and stay airborne; both use the same assembly system but behave differently based on their design and settings.
Can I disassemble a ship and rebuild it somewhere else?
Yes, use the disassemble function to convert your ship back into regular blocks, then reassemble it in a new location using the same tools.
Will this mod cause lag or performance issues?
Physics calculations add some overhead, especially with large ships or many vessels active at once; performance depends on your hardware and how many ships you're running simultaneously.
Is Valkyrien Skies required to use this mod?
Yes, Vessel Kinetic Mod is built on top of Valkyrien Skies' physics engine, so you must have the core mod installed for this to work.
