The BepInEx console will not appear when launching like it does for other games on Thunderstore (you can turn it back on in your BepInEx.cfg file). If your PEAK crashes on startup, add -dx12 to your launch parameters.

3008OstBackgroundMusic
A mod for PEAK that replaces region music with custom MP3s, supporting per-region music folders and smooth track transitions. Pre-configured with minecraft music but can be changed easily.
Features
- Plays custom MP3s for PEAK’s regions: Caldera, Kiln, and Peak.
- Automatically switches to a new random track when the current one ends.
- Configurable folder names via a config file, including an option to use vanilla Tomb music.
You can customize MP3s however you want! You can delete the included tracks and use your own. The mod plays any MP3s found in the specified folders, making it a versatile background audio mod.
Installation
- I've only installed this mod manually, its drag and drop. Not sure if it works with thunderstore mod loader thingy.

Folder Structure

folder located in BepInEx/plugins
. Inside, create subfolders for each region:
Caldera
: Music for the Caldera region.Kiln
: Music for the Kiln region.Peak
: Music for the Peak region.
Configuration
The mod generates a config file at BepInEx/config/com.mthwj.minecraftmusic.cfg
on first run. It contains entries for each region’s folder name:
CalderaFolder
: Folder for Caldera region music (default:Caldera
).KilnFolder
: Folder for Kiln region music (default:Kiln
).PeakFolder
: Folder for Peak region music (default:Peak
)..UseDefaultTombMusic
: Iftrue
, uses vanilla Tomb music instead of custom MP3s (default:true
).
Folder names can be relative to CustomBackgroundMusic
(e.g., Beach
) or absolute paths (e.g., C:\Music\Beach
). Edit the config to change folder names or point to custom locations.
Notes
- The mod is preconfigured with 3008 OST, based on the
UseDefaultTombMusic
config.
