Tip
How to use Abyss Editor:
- Click Play to enter the editor.
- Head to the gear icon to set your Subnautica installation path and adjust any settings.
- From there, load batches via an optoctreepatch file or batch numbers (findable in-game via F3 — they define a diagonal box of terrain).
- Once loaded, modify the terrain freely. Use tooltips or the help menu if you're unsure about a tool.
Loading your edits:
- Install Terrain Patcher and unzip into your Subnautica\BepInEx\plugins folder.
- You can leave patches anywhere inside your plugins folder, check in-game to see your edits.
Important
Development Setup:
- Download the repo and open it in Unity (6000.3.9f1). It may take some time to import the project fully.
- Open the MainMenu scene or the AbyssEditor scene within Assets/AbyssEditor/Scenes
- You can now use Abyss Editor through the Unity Editor or build an executable, its that easy!
