Create: Deep Diving

Take Create’s diving equipment further with underwater pressure, custom breathing gases, decompression, and a dedicated diving computer.

Currently in beta.1. The core diving systems are implemented, with balance and compatibility still being refined. Please report any bugs or problems in the comments! We are currently doing a lot of playtesting to help polish the systems and will keep adding updates and fixes.

It is highly recommended to have custom world-generation making oceans deeper than vanilla's as the default oceans are basically puddles.

Use with Fading Depths to configure proper depth-based darkness to your oceans and bodies of water!

Create Deep Seas compatibility: Sealed, dry submarine cabins act as breathable spaces stopping cylinder consumption and underwater buoyancy assistance while preserving your decompression history. Normal diving mechanics resume when you leave the cabin or enter a flooded compartment. (Currently working on even more support, not affiliated with Create Deep Seas in any way)

Diving with consequences

Depth affects pressure, breathing gas consumption, and equipment safety. Longer dives build up decompression obligations, while unsuitable gas mixtures introduce their own hazards.

• Depth-based pressure and increased gas consumption
• Nitrogen and helium tissue loading
• No-decompression time and decompression ceilings
• Ascent-rate warnings and pressure injury
• Custom Hypoxia, Nitrogen Narcosis, Oxygen Toxicity, Decompression Sickness, Pressure Injury, and Blackout effects
• Progressive visual and sound effects, with configurable intensity and reduced-motion options

Equipment & Create-powered gas production

Choose extended, twin, or compact emergency cylinders, with models based on Create’s copper backtank.

Carry a Breathing Regulator, use a Diving Lamp for underwater visibility, and enable spare cylinders as backup supplies.

The Diving Computer provides an OLED-style screen and HUD showing:

• Depth and pressure
• Gas quantity, mixture, and estimated remaining time
• No-decompression time or required stop depth
• Ascent guidance and paged warnings
• Condition explanations and recovery advice
• Configurable warning sounds and a saved mute setting

Turn rotational power into a complete cylinder-filling workshop.

• Gas Compressor: produces compressed air and fills cylinders
• Gas Separator: separates compressed air into oxygen and nitrogen
• Gas Blending Station: prepares Air, Nitrox, Trimix, Heliox, and custom mixtures
• Gas Storage Vessel: stores gas for later use
• Transport gases through Create’s pumps, pipes, and fluid tanks
• Automate cylinder handling with hoppers

Pressure curves, equipment ratings, gas consumption, and difficulty are configurable for shallow vanilla oceans or deeper modded seas, including separate settings for individual dimensions.

Choose Arcade, Standard, or Hardcore presets and adjust the experience to suit your world.
