A GTFO mod that unlocks all Vanity items locally.
The names of items that you do not own are colored with a slight red tint. (only if NoBoosters is not installed)
If you're running this mod with SimpleProgression installed, all the unlocking is handled by SimpleProgression instead, as that allows for finer control of what to unlock.
Check the readme of that mod if you're a rundown developer.
(Only applies to if not running either NoBoosters or SimpleProgression):
If for whatever reason you want to only unlock a subset of items you can create a file called AllVanity_UnlockList.json in your BepInEx/config/ folder with the contents being a json list of all the VanityItemTemplateDataBlock persistent IDs that you want to unlock:
[50,53,57,58,59,70,85,99,102,103,105,107,108,109,121,149]
This plugin won't load if DeviousLick is installed to avoid crashes.
