BLCMods Wiki

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

User Resources

Tools

General-Purpose Tools

• Borderlands Community Mod Manager (BLCMM) - 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

Modder's Tools

• 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 BLCMM'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.

Deprecated Tools

• Behavior Parser - Utility to help parse BehaviorProviderDefinition structures inside Borderlands data.
• UCP Filter Tool used to be the main mod management application for Borderlands 2/TPS, but has now been superceded by BLCMM.
• Hotfix Converter
• Hotfix Unconverter
• Borderlands 2 exe Patcher

Borderlands 3 Information

NOTE: Borderlands 3 modding is not a thing yet, and there's no timeline for it. Whatever information we have in here may not even end up being useful to whatever BL3 modding ends up looking like in the future.
