A UE4SS Lua mod for Subnautica 2: Alien Waters CL-121347 that adds proper item stacking for 51 common raw and processed materials.

All supported materials have been verified against their full asset paths and reuse the game's native Count system. This includes materials located outside the

Resourcesubdirectory, such as:

• Copper [/*]

• Copper Ingot [/*]

• Copper Wire [/*]

• Glass [/*]

• Electronic Components [/*]

• And many other common materials [/*]

[line]

Stacking System

Items of the same type are grouped into stacks of up to 10 items per logical inventory slot.

For example:

23 items → x10 + x10 + x3

The inventory capacity is calculated accordingly:

• Items 1–10 → 1 slot [/*]

• Item 11 → starts a new slot [/*]

• Item 21 → starts a third slot [/*]

• Item 31 → starts a fourth slot [/*]

The underlying Count values, synchronization, and save data remain managed by the base game.

The mod does not:

• Split inventory records [/*]

• Migrate or modify existing saves [/*]

• Permanently increase the game's base inventory capacity [/*]

[line]

Controls

Left Click

Moves 1 item, just like the vanilla game.

Shift + Left Click

Moves all items of that material.

Ctrl + Left Click

Also moves all items of that material.

Bulk transfers work across multiple

x10display stacks.

The mod directly reuses the game's native MoveAll path instead of simulating repeated clicks.

Items That Remain Unchanged

The following item categories keep their original vanilla behavior:

• Batteries [/*]

• Tools [/*]

• Food [/*]

• Drinks [/*]

• Medicine [/*]

• Creatures [/*]

• Story-related items [/*]

Only supported common raw and processed materials are affected by stacking.

[line]

Performance

The mod does not use:

• Runtime Tick handlers [/*]

• Persistent inventory broadcasts [/*]

• Periodic inventory scans [/*]

Inventory capacity is recalculated only when necessary, including:

• HUD initialization [/*]

• Item pickup [/*]

• Fish catching [/*]

• Crafting [/*]

• Inventory transfers [/*]

This keeps the runtime overhead minimal.

[line]

Requirements & Compatibility

UE4SS must be installed before using this mod.

Current compatibility baseline:

• Subnautica 2: CL-121347 [/*]

• Unreal Engine: UE5.6 [/*]

• UE4SS: 3.0.1 beta [/*]

Important: Subnautica 2 is currently in Early Access. Game updates may temporarily break compatibility, and the mod may need to be updated before it works with a newer build.

中文描述：

适用于《深海迷航2·异星水域》CL-121347 的 UE4SS Lua Mod。51 种经过完整资产路径核验的普通原料与加工材料会复用游戏原生 Count 机制，其中包含不在 Resource 子目录内的铜、铜锭、铜线、玻璃和电子元件等材料。

同类材料每 10 件划为一个显示组和逻辑库存格。例如 23 件显示为 x10、x10、x3；第 11、21、31 件会正常占用新格。底层 Count、同步与存档结构仍由原版管理，Mod 不拆库存记录、不迁移旧存档，也不永久扩大原版基础容量。

普通左键仍移动 1 件；Shift+左键或 Ctrl+左键移动该材料的全部数量，可跨多个 x10 显示组。批量移动直接复用游戏原生 MoveAll 路径，不循环模拟点击。

电池、工具、食物、饮料、药品、生物和剧情物保持原版。运行时没有 Tick、常驻库存广播或周期扫描；容量只在 HUD 初始化以及真实拾取、抓鱼、制作和转移事务完成时更新。

需要预先安装与当前游戏版本兼容的 UE4SS。当前兼容基线为 Subnautica2 CL-121347、UE5.6、UE4SS 3.0.1 beta；游戏处于抢先体验阶段，更新后可能需要等待 Mod 适配。
