RarityWeightMod is a R.E.P.O. mod that controls how many cosmetic boxes spawn per level and the rarity weight of each tier.
BepInEx/config/com.yourname.rarityweightmod.cfg or use in-game SettingsF5 — Open/Close Settings Panel
F6 — Toggle Box Markers
Volume_Offline (requires all players to have the mod)
Spawns up to BoxCount boxes per level, limited by available spawn volumes. Stops naturally when no volumes remain.
All_Offline (requires all players to have the mod)
Forces BoxCount boxes using a compensation window of BoxCount × 3 - 1 attempts. More reliable than Volume on smaller levels.
AutoLevel_Online (host-only — friends do not need the mod) Automatically spawns the maximum number of boxes the current level allows to extract. Scales with progression:
| Levels completed | Can sell per level |
|---|---|
| 1–5 | 1 box |
| 6–10 | 2 boxes |
| 11+ | 3 boxes (max) |
Values depend on cosmeticWorldObjectsLevelLoop (5) and cosmeticWorldObjectsLevelLoopsMax (2) from the game's ValuableDirector.
Press F5 during gameplay to open the Settings panel. All options can be changed in real-time.

[RarityWeights]
## Weights are ratios. Example: 60:25:12:3 gives ~60% Common, ~25% Uncommon, ~12% Rare, ~3% UltraRare.
## Setting all four equal gives 25% chance per tier.
# Default: 60
