10. Stack Size Controller – Quick Setup Guide

Configure the plugin behavior

  • ‘RevertStackSizesToVanillaOnUnload’ – When set to true, all item stack sizes revert to the default Rust values whenever the plugin is unloaded.
  • ‘AllowStackingItemsWithDurability’ – Enables stacking for items that have durability (like weapons) only if they are at full durability. If disabled, these items cannot be stacked. All contents, attachments, and ammo are returned to the player.
  • ‘HidePrefixWithPluginNameInMessages’ – Currently has no effect. Future updates will remove the plugin name prefix from in-game chat messages.
  • ‘GlobalStackMultiplier’ – Multiplies the stack size for all items by the specified value.

Set the Category Stack Multipliers

‘IndividualItemStackMultipliers’ – Allows defining a multiplier for each item using its “item_id”.

Use stacksizecontroller.itemsearch in your console to easily find the correct ID.

For example:
stacksizecontroller.itemsearch stone
The console will return → Found item: stone, ID: 12345
