Pack Format

A tattoo pack is a plain folder - no code. It lives under:

…/Schedule I/UserData/Inkorporated/Packs/<YourPackName>/
    manifest.json
    one or more .png files

Inkorporated scans every folder in Packs/ at startup and loads each one that has a manifest.json.

manifest.json

{
  "name": "My Pack",
  "author": "you",
  "tattoos": [
    { "id": "skull", "name": "Skull",    "placement": "chest",   "file": "skull.png" },
    { "id": "tear",  "name": "Teardrop", "placement": "face",     "file": "tear.png", "price": 250 },
    { "id": "sleeve","name": "Full Sleeve","placement": "leftarm","file": "sleeve.png" }
  ]
}

Top level

Field	Required	Notes
`name`	no	Pack name, shown in the load log.
`author`	no	Your name.
`tattoos`	yes	Array of tattoo entries (below).

Each tattoo entry

Field	Required	Notes
`id`	yes	Unique within this pack. Lowercase, no spaces (used in the registered resource path).
`name`	no	The label on the shop button. Falls back to `id`.
`placement`	yes	`chest` \| `leftarm` \| `rightarm` \| `face` (case-insensitive; `left`/`right`/`left_arm`/`right_arm` also accepted).
`file`	no	PNG filename in the pack folder. Defaults to `<id>.png`.
`price`	no	Shop price. Omit or `0` for “Free”.

Entries with an unknown placement, a missing id, or a missing PNG file are skipped with a warning in the MelonLoader log - check it if a tattoo does not show up.

The PNGs

Each file is a transparent PNG whose opaque pixels sit at the UV region of that body part. This is the one thing to get right - a tattoo is a full skin-texture layer, not a centered sticker. Read Authoring Tattoos before drawing. Recommended canvas: 2048x2048 for body/arms, 512x512 for face (there is no hard size limit; you can do a full sleeve).

Shipping a pack as a mod

A pack folder is already a complete mod. To distribute it on Thunderstore, zip the pack so it extracts to UserData/Inkorporated/Packs/<YourPackName>/, and declare DooDesch-Inkorporated as a dependency in your manifest.json (Thunderstore one) so installers pull the framework in. See the example repo’s pack/ folder for a ready template.
