How to Build and Assemble a Custom Submarine

Designing the Vessel Hull

To build a functional submarine, construct a sealed hull using your choice of building materials, such as oxidized copper blocks and clear glass windows.

1. Lay down an enclosed exterior shell, ensuring there are viewing ports to look out at kelp and underwater terrain.

2. Design an interior hallway and cabin space with room for lanterns, mechanical gears, and operating stations.

3. Integrate space for your operational systems and power lines before closing up the vessel walls.

Assembling as a Physics Craft

Because the mod extends Create and Create Aeronautics, custom watercraft must be compiled into moving entities before they can move with real physics.

1. Confirm the entire structure is fully built and connected according to Aeronautics vehicle assembly requirements.

2. Activate the assembly mechanism to convert the static block structure into an active physics vessel.

3. Verify that the craft floats stably on the surface of the calm ocean before initiating any deep-water dives. The underlying Sable physics engine will handle fluid movement and weight distribution once assembled.
