Wet System Framework

Wet System - Custom Decorative Objects

WET System Framework is a modding framework for Subnautica 2 that allows anyone to add custom decorative objects and meshes to the game without writing code.

Using simple .wet.json files placed in the ~mods folder, modders can create new placeable decorations that automatically appear in a dedicated in-game menu (UI is WIP).

Installation

You need UE4SS

Place "WetSystem" inside: Subnautica2\Subnautica2\Content\Paks\LogicMods

Place "WetScript" inside: Subnautica2\Subnautica2\Binaries\Win64\ue4ss\Mods

Be careful to have "WetScript : 1" (if not add it) inside ue4ss\Mods\mods.txt

If, in the menu, you see "Wet System" below the logo, that's good!

Press F9 to open the WET Framework object menu.

From there, you can browse and place any registered custom object.
