Inkubator - In-Game Tattoo Pack Editor for Schedule I

🛟 Need help or found a bug? Get support at support.doodesch.de/inkubator.

Make a tattoo pack without ever leaving the game. Inkubator opens a 3D tattoo editor right from the main menu: import your PNGs, place and scale them on the character, preview them live on the real menu rig, and export a complete, ready-to-publish Inkorporated tattoo mod - manifest, license and a resized icon included. Built on S1API and launched through the Side Hustle hub.

Features

• In-game tattoo editor - design a whole pack from the main menu, no image software or JSON needed.
• Import and place - drop PNGs in a folder, then place, move, scale, rotate and flip each tattoo on a UV canvas.
• Live preview - every change is baked onto the menu character instantly, with turn and camera-zoom controls.
• Chest, arms and face - author tattoos per body part, each with its own name, shop price and shop id.
• One-click export - produces a complete Inkorporated pack (manifest, baked textures, README, LICENSE and a 256x256 icon, auto-resized from any source image).

Requirements

• Schedule I (IL2CPP, current Steam public build)
• MelonLoader 0.7.3+
• S1API (ifBars/S1API_Forked) - pulled in as a dependency
• Side Hustle - the main-menu hub Inkubator launches from
• Inkorporated - only needed to use the packs you export, not to run the editor

How it works

Open Side Hustle from the main menu and launch Inkubator. Drop your PNGs in the import folder, place them on the character per body part, set names and prices, fill in the pack details and hit Export. Your finished pack lands in UserData/Inkubator/Exports/, ready to zip and upload. Anyone who installs your pack together with Inkorporated gets your tattoos in the in-game tattoo shop.

Changelog

All notable changes to Inkubator are documented here. This project adheres to Semantic Versioning.

[1.0.4] - 2026-08-01

Changed

• Runs on Schedule I 0.4.6f11.
• Needs S1API 3.1.1, up from 3.0.5. Update it along with the mod.

[1.0.3] - 2026-07-27

Added

• Full body canvas mode. 1.0.2 framed the canvas on the selected body part, which fixed tattoos landing in the wrong place but also locked you out of everywhere the game has no stock tattoo for: forearms, hands, shoulders, belly, legs, back and the back of the head. A Part / Full body switch under the canvas now opens the whole skin, and the faint backdrop turns into a map of the body so you can see where you are aiming. The body part you picked still decides how the tattoo is exported - the switch only changes what you are looking at.

[1.0.2] - 2026-07-27

Fixed

• Tattoos now land on the body part you picked. Chest, left arm and right arm are three small islands in one shared texture wrapped around the whole body, so choosing a placement never actually moved an image and a new tattoo started on none of them. The canvas now frames the body part you are editing, a new tattoo starts on it, and dragging stays there.
• The faint "inked region" reference behind the canvas is finally visible. It never loaded outside a development build, so on a normal install you were placing tattoos on a blank square.
• "Hide clothes" actually hides the clothes. The game clears only six of its eight avatar layer slots, so a shirt and jeans could stay stuck on the character while everything else said they were gone.
• Tattoos no longer look darker than they should. The same slot leak could composite one layer several times over, which read as a tint that nothing removed.
• A tattoo no longer disappears without explanation. Past eight body layers the game silently drops one; the editor now hides one of the character's own tattoos instead and says so.
• The clothes and underwear buttons no longer double as a click on the character behind them, which turned the model and triggered a redundant re-bake on every toggle.

[1.0.1] - 2026-07-10

Fixed

• Nexus/Vortex: the download now ships the DLL under a mods/ folder so Vortex installs it correctly. The old flat archive could make Vortex deploy a stray "mods" file into the game folder and break the Mods directory - if Inkubator never showed up for you after a Vortex install, this was why. Manual installs and Thunderstore were never affected.

[1.0.0] - 2026-06-24

Initial release.

Added

• In-game 3D tattoo editor, launched from the main menu through the Side Hustle hub.
• Import PNGs and place, move, scale, rotate and flip tattoos on a per-body-part UV canvas (chest, arms, face).
• Live preview baked onto the real menu character, with turn and camera-zoom controls that follow the face when editing face tattoos.
• Per-tattoo name, shop price and auto-generated shop id.
• In-app icon picker that resizes the chosen cover image to Thunderstore's 256x256 on export.
• One-click export of a complete, ready-to-publish Inkorporated tattoo pack (manifest, baked textures, README, LICENSE and icon).
