Increases backpack inventory space by resizing grids. Supports custom sizes and blacklist.
Jero’s Backpack Rework
Inspired by Josh Mate’s Better Backpacks mod.
This mod automatically resizes backpack grids to provide more logical inventory space. Automatically detects all backpacks by Parent ID, working with vanilla and modded backpacks.
Configuration
Default Size Mappings
| Old HxV > | New HxV |
|---|---|
| 6x8 | 6x11 |
| 6x7 | 6x10 |
| 5x7 | 5x10 |
| 5x6 | 5x8 |
| 3x8 | 4x9 |
| 5x5 | 5x7 |
| 5x4 | 5x6 |
| 4x5 | 5x6 |
| 4x4 | 4x6 |
| 2x7 | 3x7 |
| 4x3 | 4x4 |
| 3x4 | 4x4 |
| 3x3 | 4x3 |
| 4x2 | 4x3 |
| 3x2 | 3x3 |
Modify size mappings in config.json.
Important: When modifying config.json, only change NewHorizontal and NewVertical values. Do not modify OldHorizontal and OldVertical - these are used as keys to match backpacks and changing them will break the mapping.
Custom Sizes (item.json)
Set specific sizes for individual backpacks:
{
"Backpacks": {
"itemId": { "ItemName": "Name", "Horizontal": 6, "Vertical": 11 }
}
}
Blacklist (blacklist.json)
Exclude backpacks from resizing:
{
"Blacklist": {
"itemId": { "ItemName": "Name" }
}
}
Note: Backpacks with multiple grids are automatically skipped and cannot be resized.

Introduce external JSON configuration
This refactor fundamentally changes how the mod is configured by moving all backpack size data from a hardcoded dictionary into an external config/config.json file.
Allows users to easily customize backpack sizes without recompiling the mod.
The mod now reads all settings from the JSON file on server startup.
Added a non-functional 'ItemName' field to the config for better readability and user experience.
Bumps the mod version to 2.0.0 to reflect this significant breaking change.

Zip contents folder is wrong. It expands to mod folder, instead of bepinex folder.
The maths on the description is absolutely butchered.
Old HxV > New HxV > Increase %
6x8 6x11 37.50% -> 37.3% (Within margin of rounding, so a pass)
6x7 6x10 42.86% -> 30%
5x7 5x10 42.86% -> 30%
5x6 5x8 33.33% -> 25%
3x8 4x9 50.00% -> 33.33%
5x5 5x7 40.00% -> 28.58%
5x4 5x6 50.00% -> 33.33%
4x5 5x6 50.00% -> 33.33%
4x4 4x6 50.00% -> 33.33%
2x7 3x7 50.00% -> 33.33%
4x3 4x4 33.33% -> 25%
3x4 4x4 33.33% -> 25%
3x3 4x3 33.33% -> 25%
4x2 4x3 50.00% -> 33.33%
3x2 3x3 50.00% -> 33.33%
Literally unplayable. Pls fix. /s
Hello, can I change the size of the backpacks at my discretion using this mod?*(*Machine translation)
Hello there, Windows Defender auto-deleted the file on download because of Trojan
https://gyazo.com/a848630946d25b93764ca5d5ca7eb066
Windows Defender often marks most mods as viruses; just disable windows defender before you install this mod, or really any mod.
I’ve deleted my previous comment acusatory of it being a virus, I’ve been corrected and i was not following the SPT discord to know it was copy paste. I apologize
unzipped content is just a dll file, no folder, is it right?
