Build In Seatruck Plus

AI VIBE CODED PROJECT. CLAUDE CHAT LOG INCLUDED

Build inside your Seatruck — and bring the music with you.

A Subnautica: Below Zero mod with two headline features:

• 🛠️ Build In Seatruck — use the Habitat Builder to place buildables inside

your Seatruck. Lockers, fabricators, planters, decorations — they ride with the

vehicle, and detaching/reattaching modules works as expected. This is a BepInEx

port, updated for the current game, of BluesKutya's Build In Seatruck.

• 🎵 Mini Jukebox & Speakers — compact, Seatruck-sized buildables that play

the music tracks you've unlocked from Jukebox Disks, plus a hotkey to control

playback on the move.

Features

🛠️ Build In Seatruck

• Place buildables inside any Seatruck segment with the Habitat Builder.
• Everything parents to the segment, so it rides with the Seatruck as you drive.
• Detach and reattach modules freely — your builds stay put.
• Normal base and world building are completely untouched (the Seatruck handling

is scoped to when you're actually standing in a Seatruck).

🎵 Mini Jukebox & Speakers

• Mini Jukebox — a 25%-scale buildable jukebox that fits the Seatruck. Plays

your unlocked tracks through the game's own jukebox engine, with the normal

in-world play / pause / next / shuffle / repeat / volume screen.

• Mini Speaker — a 50%-scale speaker so the music is clear inside the cramped cab.
• Very liberal placement collision on both, so they're easy to fit.

⌨️ Playback hotkey

While inside a Seatruck or base:

• Hold the key (default R) → start / stop playback.
• Tap the key → skip to the next track (with a "Now playing" toast).

⚙️ In-game options (Nautilus Mod Options)

Rebind the hotkey, tune long-press timing, cheap recipe, unlock toggle, default

shuffle, and notifications.

Requirements

| Dependency | Notes |

|------------|-------|

| Subnautica: Below Zero | Current Steam build |

| BepInEx for Below Zero | Tobey's BepInEx Pack for Subnautica: Below Zero (BepInEx 5.4.x) |

| Nautilus | 1.0.0 or newer — GitHub releases |

Nautilus and BepInEx must be installed first. Nautilus is not,

so mod-manager users still have to install it manually into BepInEx/plugins

(the manager will pull in the BepInEx pack, but not Nautilus).

Installation

Manual

• Install the BepInEx pack and Nautilus (see Requirements).
• Download BuildInSeatruckPlus-x.y.z.zip from the

Releases page.

• Extract it so that the file lands at:

/BepInEx/plugins/BuildInSeatruckPlus/BuildInSeatruckPlus.dll

• Launch the game.

Mod manager (r2modman)

Install Nautilus and this mod; the manager handles dependencies.

Usage

Building in the Seatruck

Get inside a Seatruck, equip the Habitat Builder, and build as you normally

would in a base. The placement ghost turns green inside the cab and attached

modules; whatever you place rides along when you drive.

The jukebox

• Unlock the mini buildables. By default the Mini Jukebox & Mini Speaker

unlock alongside the vanilla Jukebox (find Jukebox Disks / scan Jukebox

fragments). Prefer them from the start? Tick "Unlock buildables at start"

in the mod options and restart.

• Build a Mini Jukebox (and a Mini Speaker or two) in your Seatruck — they

share the vanilla Jukebox's build-menu category.

• Play music:
• Walk up and click the jukebox's screen, or
• Use the hotkey: hold R to start/stop, tap R to skip. Only active

while you're inside a Seatruck or base.

Songs are the ones you've unlocked from Jukebox Disks — the mod uses the game's

own unlocked-track playlist, so there's nothing extra to manage.
