sniff sniff... Smells like... an off-worlder. How are you liking our wiki, anyways?
the wiki is
always under heavy development, if you have any knowledge to share, please do so
This wiki attempts to serve as a central documentation point for dealing with Borderlands modding, specifically for Borderlands 2, The Pre-Sequel, Borderlands 3, and Tiny Tina's Wonderlands. (For BL1, you'll have to look elsewhere, alas.) There's information for people who just want to run mods, but the majority of the info is more geared towards folks who want to write mods themselves.
Most of the links down below are BL2/TPS-specific; we've got pages set up for Borderlands 3 and Tiny Tina's Wonderlands here:
Or you can jump straight to the mod cabinets here:
Get started by installing Python SDK to set up the game for modding and allow the use of SDK mods. If you need to configure text mods you want to use the Borderlands Community Mod Manager (OpenBLCMM), which is the new replacement for FilterTool!
- Functional Changes from FilterTool to BLCMM
- Text Mod Setup Guide
- Linux and Mac Setup Gotchas
- Patching FaQ
- Randomizer PythonSDK FaQ
- Hex Edits (mostly unnecessary since PythonSDK exists)
- Borderlands Community Mod Manager (OpenBLCMM) - Highly recommended mod management tool. You want to be using this to manage your mods, both for authors and users.
- Borderlands Hex Multitool - Patches Borderlands to do things like raise the maximum character level, backpack size, money, etc.
- BL2 Gibbed save editor - savegame editor for BL2 saves
- TPS Gibbed save editor - savegame editor for TPS saves
- Unreal Package Decompressor - Required if you want to dig into Borderlands's UPK content directly
- UE Explorer - Lets you browse around Borderlands UPK files directly; very useful if the data you're looking for isn't already bundled with FilterTool. Requires that the UPKs be decompressed with the Unreal Package Decompressor first.
- FilterTool Explorer - Provides a tree-like view into OpenBLCMM's bundled object information, like UE Explorer does, but without needing to deal with UPKs.
- Balanced Items Generator - Little utility to help visualize BalancedItems probabilities, and assist in figuring out the values you might want to change, for a mod.
Behavior Parser - Utility to help parse
BehaviorProviderDefinitionstructures inside Borderlands data.
- Hotfix Converter
- Hotfix Unconverter
- Borderlands 2 exe Patcher

(If you don't know what this is already, it's not for you. They're quite complex. Get used to modding other stuff first, and then come back here once you've levelled up a few times.)
