📋 About This Mod

NOTICE: This mod is now OBSOLETE! Please use Fixes for continued support. Oxygen Pipe Biome Fix will still work for now but future support is canceled

Oxygen Pipe Biome Fix

Fix oxygen pipes not being able to go between sub-biomes in the crash zone. Biomes like the Crash Zone_Mesa and Crash Zone_Trench are practically impossible to make pipes around without this mod. Colliders block the checks used to allow pipes to connect, this mod simply disables the ability for ray casts to hit those colliders and block the pipe placement in perfectly open water. Simply drop the dll into your bepinex plugins folder and your good to go, no config needed.

I would recommend Highly watching the mod's video to understand exactly what this mod does.

  • The Problem

The oxygen pipe placement does a raycast between the position it wants to place the new end, and the old one. In the Crash Zone specifically, there are sub-biomes (that I don't believe are anywhere else in the game) that have colliders that detect when the player enters the trench or mesa sub zone. These colliders (that are seen in the video) interfere with that raycast that is sent when placing a pipe, not allowing the player to create a pipe between the sub-biomes of the Crash Zone. This mod simply disables the ability for raycasts to hit those colliders, but still allows them to detect the player entering them.

  • Tiny download (190 downloads) but exactly what it says on the tin.
  • No extra bloat—just the fix, no gameplay changes.

⚠️ Cons

💡 Beginner Tips

  • Place the mod files directly into your Subnautica 'BepInEx/plugins' folder if you're using BepInEx—most mods for this game work that way.
  • Test pipe placement in the Crash Zone_Mesa area first to confirm the fix works before building a full base.
  • Check the mod's page for any dependencies like QModManager—if none are listed, it likely works standalone.
