Bigger Item Stack

Customize item stack limits, item weights and player carry capacity in Valheim.

Made by sixefyle.

What's new in 2.0.0

• Server/client configuration synchronization through Jötunn.
• Server settings are applied to connected clients, and only server administrators can change synchronized settings during a session.
• Fixed cumulative multiplier application that could turn a stack limit of 250 into 1250 with a multiplier of 5.
• Existing items and player carry capacity are updated when settings change.
• Cached inventory weights are recalculated after configuration changes.

Starting with 2.0.0, this mod and Jötunn must be installed on the server and every client. It is also usable in single-player with the same dependencies. This changes the installation requirements of earlier releases.

Requirements

• BepInExPack for Valheim.
• Jötunn 2.30.2 or newer — a required dependency.
• Compatible mod versions on the server and clients: the major and minor version numbers must match. For example, 1.3.x clients cannot connect to a server running 2.0.x.

Installation

With a mod manager

Install BiggerItemStack and its dependencies using your Valheim mod manager. Install the mod and dependencies on your server as well as all clients, and launch the game through the mod manager.

Manually

1. Install BepInEx for Valheim.
2. Install Jötunn 2.30.2 or newer using its installation instructions.
3. Copy BepInEx/plugins/BiggerItemStack/BiggerItemStack.dll from this archive into the corresponding folder of your Valheim or dedicated server installation.
4. Start the game or server once to create the configuration file.

When updating, replace the old DLL and keep only one active copy of BiggerItemStack. Keep your existing configuration file: its name and setting keys are unchanged.

Configuration

Configuration file:

BepInEx/config/org.bepinex.plugins.bigger_item_Stack.cfg

All three settings are in the [Multiplier] section.

Setting	Default	Description
ItemMaxStackMultiplier	2	Multiplies the maximum stack size of stackable items. Fractional values such as 1.5 are supported.
ItemWeightMultiplier	1	Multiplies item weight. Use 0.5 for half weight or 0 for weightless items.
PlayerWeightMultiplier	1	Multiplies the player's base carry capacity. Equipment and status-effect bonuses are applied afterward by Valheim.

Example:

[Multiplier]
ItemMaxStackMultiplier = 5
ItemWeightMultiplier = 0.5
PlayerWeightMultiplier = 1.5

For an item whose original stack limit is 50, a multiplier of 5 produces a limit of 250. Reapplying the multiplier uses the original value instead of multiplying 250 again.

Multiplayer

Edit the configuration on the server, then restart the server to load file edits. Clients receive the server values when connecting. Client settings are restored when disconnecting.

Server administrators can also use a Jötunn-compatible configuration interface to change settings during a session. An interface is optional and is not included in this package. This mod does not automatically watch configuration files for changes on disk.

Single-player

Your local configuration controls the multipliers.

Limits and compatibility

• Items that cannot normally stack remain unstackable.
• Stack and carry capacity multipliers accept values from 0.01 to 1000. Item weight accepts values from 0 to 1000.
• Calculated stack limits are capped at 65,535 to fit Valheim's inventory serialization format.
• Reducing a stack limit does not automatically split existing oversized stacks. Split oversized stacks before reducing your settings or removing the mod.
• Other mods that modify the same item weights, stack limits or player carry capacity may conflict with these changes.

Release validation

Compiled against the locally installed Valheim build and Jötunn 2.30.2. All 29 automated checks passed, including the repeated-multiplier regression case. In-game server/client testing is still pending.
