Multi-Skin

A Fabric mod for Minecraft 1.21.1 that adds custom skins, body part management, and player size adjustment.

Skins

Open the skin menu by pressing F12. It allows you to create, edit, duplicate, and delete skins, organize them into folders, and customize their model (slim or steve), size, and hidden body parts. Skin images can be loaded from a URL or a local file.

The local skin library is stored in multi-skin/skins/ inside the game directory. Player height can be set between 50 and 300 cm, with a default value of 185 cm.

Skin commands apply to the player executing them:

/skin slim <url> [size_in_cm]
/skin steve <url> [size_in_cm]
/skin reset

Operators can also apply or reset skins for other players:

/skinadmin <players> slim <url> [size_in_cm]
/skinadmin <players> steve <url> [size_in_cm]
/skinadmin <players> reset

Body Parts

Operators can hide or restore players' arms and legs. The selected body parts configured in a skin are applied along with that skin.

/bodypart remove <players> arm right
/bodypart add <players> leg left
/bodypart reset <players>

Player Size

Player size changes the player's scale. Operators can configure how size affects movement speed and reach using the following commands:

/multiskinconfig get
/multiskinconfig size speed <coefficient>
/multiskinconfig size reach <coefficient>
/multiskinconfig reload

Coefficients range from 0.0 to 2.0. The configuration is stored in config/multi-skin/config.json.

The maximum allowed skin image size can be configured separately. Operators can choose a limit of 64, 128, 256, 512, or 1024 pixels:

/multiskinconfig skin size <64|128|256|512|1024>
/multiskinconfig get skin size

The selected limit also allows all smaller supported sizes. For example, a limit of 512 accepts skins at 64×64, 128×128, 256×256, and 512×512.

The default limit is 1024. The configuration is stored in config/multi-skin/config.json.
