First Person Cosmetics

Makes PEAK's built-in eyepatch, glasses, mask, hat, helmet, and eye cosmetics functional.

The eyepatch obstructs the screen-left eye with a soft center fade. Tiny Sunglasses apply a black tint at 75% opacity. Aviators apply the reference image's #C5987D tint at 35% opacity. Round Glasses have no screen effect. Broken Glasses spread fractures and triangular shards across the whole screen. The Plague Doctor mask adds a neon-green #39FF14 tint at 35% opacity. The Astronaut helmet adds a muted purple #555F9A tint at 20% opacity, while the Racing Helmet adds a cyan-blue #40BDC9 tint at 25% opacity. The Pumpkin displays a PEAK-shaped carved face around the player's view, the SleepyGuy hat fades inward from black at the top and bottom while leaving a clear horizontal middle band, and the crying eyes show a visibly softened low-resolution view of the 3D scene. Hat, accessory, and eye effects can appear together.

Installation

Install with the Thunderstore Mod Manager:

1. Select the PEAK profile.
2. Install BepInExPack PEAK.
3. Install First Person Cosmetics.

The configuration file is created at BepInEx/config/firstpersoncosmetics.cfg.

Configuration

• Effect > Maximum opacity: blackness at the outside edge.
• Effect > Center fade width: how far the effect fades before the center of the screen. The default is 10% of the full screen.
• Tiny Sunglasses > Black tint opacity: Tiny Sunglasses tint strength. The default is 75%.
• General > Enabled: turn the effect off without uninstalling.
• Debug > Log cosmetic detection: logs the selected cosmetics, asset names, and active effects.

The detector reads the local player's selected accessory, hat, and eyes from PEAK's persistent player data. It recognizes the built-in eyepatch, Aviators, Tiny Sunglasses, Broken Glasses, Plague Doctor mask, Astronaut helmet, Racing Helmet, Pumpkin, SleepyGuy hat, and crying eyes assets.

Building for Thunderstore

This repository contains the source project rather than a precompiled DLL because the plugin must reference the PEAK assemblies from your own installation.

On Windows with the .NET SDK installed, run PowerShell from this folder:

.\build.ps1 -GameDir "C:\Program Files (x86)\Steam\steamapps\common\PEAK"

The GameDir value must point to the folder containing PEAK.exe and the PEAK_Data folder. The build project now references the Unity DLLs explicitly, which avoids a Windows MSBuild wildcard issue.

Upload the generated bin\FirstPersonCosmetics.zip to Thunderstore. The ZIP already has the required manifest.json, README.md, CHANGELOG.md, icon.png, and BepInEx/plugins/FirstPersonCosmetics/FirstPersonCosmetics.dll layout.
