Stackable Resources

What it does

Visual stacking, automatic. Any time the inventory updates — picking up, dropping, crafting, moving between containers — duplicates collapse into one cell with the count painted on top.

Works everywhere the inventory does. Player inventory, base lockers, vehicle storage, fabricator interfaces — same behavior across all of them. 

Tunable stack size. Default is 5 items per visual cell; anything above splits into another stack. Crank it to 50 if you want every titanium hoard you've ever scrounged to lump into one badge. 

No game balance change. Pure visual — the game still thinks of items individually. Crafting, container capacity, and item movement all work exactly as the base game does.

How it works (briefly)

The mod hooks the inventory's update events and, once per refresh, walks the visible cells, groups same-type entries by their parent grid, keeps one cell visible per stack with an xN badge, and collapses the rest. Nothing is written to your save — everything is recomputed live from whatever the game currently shows.

While the inventory is rebuilding (the brief window where the game has the data but hasn't finished painting it), the grid is hidden so you don't see a single-frame flash of un-stacked cells before stacking lands. The grid reveals as soon as stacking is applied, typically within a frame or two.

Settings (via SN2ModSettings)

If you have the SN2ModSettings mod installed, an in-game options panel appears with:

• Enabled — master on/off. When off, the inventory renders unchanged (no grouping, no badges).[/*]

• MaxStackSize — items per visual cell before splitting into another stack (1–50, default 5). Set to 50 to effectively lump every duplicate of a type into one cell.[/*]

Settings apply within a couple of seconds of saving in the options UI — no restart required.

Without SN2ModSettings the mod still works fine — it just uses defaults (MaxStackSize = 5, enabled).

Requirements

• UE4SS — required.[/*]

• SN2ModSettings — optional but recommended for the in-game settings panel.[/*]

Installation

Install UE4SS for Subnautica 2 if you haven't already. Extract the archive into Subnautica2 Binaries Win64 ue4ss Mods — you should end up with a folder named StackableResources alongside your other mods.

Launch the game. Open any inventory or locker and duplicates should immediately collapse into xN stacks.

Compatibility

Should play nicely with any other UE4SS mod. The mod only touches the visibility state of inventory entry widgets — no save data is read or written, no game state is modified, no items are created or destroyed. Disabling or removing the mod returns the inventory to its untouched per-cell display the next time it refreshes.

Troubleshooting

Nothing stacks? Make sure Enabled is on (in SN2ModSettings, if installed), and verify ue4ss/Mods/StackableResources/ is present and not disabled in the UE4SS mods list. 

Counts look wrong? The badge shows the number of items collapsed into that cell — if your MaxStackSize is 5 and you have 12 copper, you'll see x5 / x5 / x2 across three cells, not one x12. Bump MaxStackSize if you want fewer split cells.

Brief blank inventory when opening? That's the grid-cloak — it's hiding the un-stacked first paint so you don't see a flash of duplicates. Should last at most ~150ms; if it's longer, please file an issue with your UE4SS log.

Want everything in one cell? Set MaxStackSize to 50 in SN2ModSettings.
