BepInEx/config/hex.waterproofbuilding.cfg

Example configuration:

[General]

## Enable or disable the mod
# Setting type: Boolean
# Default value: true
Enabled = true

⚠️ Changes to the Enabled setting require a full game restart.

Waterproof pieces are registered during game initialization and cannot be safely removed at runtime.

Install using a Thunderstore-compatible mod manager such as r2modman.

⚠️ Multiplayer compatibility has NOT been fully tested.

This mod has primarily been tested in single-player/client-side environments.

If using in multiplayer, installing the mod on both the server and all clients is recommended for the best chance of consistent behavior.

Potential multiplayer issues may include:

Use in multiplayer at your own risk until additional testing is completed.

Uses Jotunn for prefab and piece registration
Lightweight Harmony patching
Designed to minimize conflicts with other mods
Waterproof variants are separate prefabs and do not modify vanilla assets directly

Only buildable pieces are affected
Existing vanilla pieces are unchanged
Safe to add to an existing world
Removing the mod may leave placed waterproof pieces unavailable or non-interactable
