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
Source Code can be found here
Oxygen Pipe Biome Fix is a small gameplay mod for Subnautica that resolves a bug preventing oxygen pipes from being placed between sub-biomes in the crash zone, such as Crash Zone_Mesa and Crash Zone_Trench. With only 2 endorsements and 190 downloads, it's a niche fix for players building bases in those areas.
✨ Key Features
📊 Pros & Cons
✅ Pros
- Solves a real headache for base builders in the crash zone—pipes actually connect now.
- Tiny download (190 downloads) but exactly what it says on the tin.
- No extra bloat—just the fix, no gameplay changes.
⚠️ Cons
- Only 2 endorsements—barely anyone has vouched for it, so you're flying blind.
- Last updated August 2025—might not be tested against the latest game version.
For Subnautica base builders who've rage-quit trying to run oxygen pipes through the crash zone's sub-biomes. If you're not building there, skip it—this is a hyper-specific fix.
💡 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.
