Skin

Skins refer to the textures that are placed onto a player or mob model.

Properties
Skins are divided into areas that act as the surface area of the character (for example, the front head area, left leg area, etc.). A skin will only allow solid color; transparency is not allowed on the skin file except on the second layer, which is transparent by default; playing offline, pixels can be left free resulting in "holes" in the skin. If a skin with transparent pixels on the first layer is uploaded, the transparent pixels will render as black pixels in-game. The second layer can be used to give the character glasses, hats, or other accessories (even a bigger head).

World textures
A skin can also refer to other textures in the game, such as block textures, item sprites, mob skins, etc. A list of these can be found here.

It is worth noting that zombie and zombie pigmen mobs can use typical player skins (and vice-versa). Skeleton mobs can use typical player skins as well, but keep in mind that they have their skinny arms and legs. (If a skeleton mob skin is used as a player's skin, their legs and arms will not be skinny.)

In order to use the player skin for zombies and zombie pigmen, the user must align it to the correct place on the .png or the texture will be broken.

Java Edition
A player can only change their character's skin if they have purchased Minecraft. This is done on the profile page by uploading a valid  or   image file, which will then replace the default skin.

Skins also have the option of having 3 or 4 pixel wide arms, which can be changed on the profile page as well.

The  and   files in minecraft.jar can also be changed and replaced via a resource pack, but the effects will only be visible to players using the resource pack, and will affect all players with the default skin.

Legacy Console Edition


There are currently 18 default skin types (with the exception of the skin packs), 9 of which are based on the Steve model and the other 9 based on the Alex model, wearing different outfits and skin colors. The skins are available to be chosen in the 'Change Skin' area of Help & Options. There are also a few other skins with the name of Alex or Steve, but they aren't default, such as developer Alex or party Steve. The Legacy Console Edition allows transparent skins, because the player cannot create their own skins. This prevents issues with completely transparent skin users "haunting" other players. The player can add custom skins to the Legacy Console Edition via hacking; however, this will void the warranty of the console, and the player risks a ban from either Xbox Live or PlayStation Network for an illicitly modded game or console.

Other versions of Steve and Alex in officially-released skin packs exist:

Bedrock Edition
Since Pocket Edition Alpha 0.11.0, Players can choose one of the two default skins either Steve or Alex, and can apply their own custom skin. (Uses the same format as the Java edition). The player must select a valid skin image from their photo library, and will then be prompted to choose between the two main models. Players can also buy skin packs which are purchased with Minecraft Coins. Those skin packs are as follows:Norse Mythology Skin Pack, Steampunk Skin Pack, Fallout Skin Pack, Power Rangers, Chinese Mythology Skin Pack, Greek Mythology skin pack,Magic:The Gathering ,Skyrim "Strangers" Biome Settlers Pack 3 Festive Mashup 2016 skin pack, Campfire Tales, the Minecon skin pack, Villains, Biome Settlers Pack 2, Story Mode Skin Pack, Redstone Specialists, Journey To The West, Holiday Skin Pack 2015, Biome Settlers Pack 1, Halloween Costumes, City Folk, Town Folk and other community-created skin packs. The Legacy Skin Pack was also implemented in Bedrock Edition, but the player has to sign in to Xbox Live to access all the skins. It also includes five anonymous skins. Players can also make their own skin packs, which must include a manifest.json file, a skins.json file, and all the desired skins. An additional .lang file can be added inside a folder labeled texts to display the skin names, but the game can register the skins without it.

In addition, Bedrock Edition has the option to use skins with double the resolution of a normal skin. This means the skin template can be up to 128x128 instead of just 64x64. The normal templates still apply, but players get 4x the amount of pixels to work with, since both dimensions have been doubled. and you can use transparency even on first layer. but you need at least one visible pixel on five bodypart. so you cant't make fully invisible skin. and transparency must be 0% or 100%. Translucent color is not allowed in both layer.

Skin packs


Skin Packs are available in the Legacy Console Edition and in the Bedrock Edition as downloadable content. Skin Packs add additional skins that players may choose from along with the 16 default skins (2 in Bedrock Edition) packaged with the game. They often feature characters from other video games, alongside original designs.

Creating a skin
Many players prefer their own unique skin, something which describes them. While many premade skins can be found online, many players prefer to create their own.

A custom skin is a way to personalize the player model and can be done either by using a variety of community-made skin editors, or by editing the or  file manually with an image editor like Photoshop, GIMP, Paint.net or similar image editors. The file can be downloaded here and the  file here. When editing the or  file manually, be sure to keep the original image dimensions and make the background of the skin (the unused pixels) completely transparent. Otherwise, Minecraft may fail to recognize the skin as intended.

Alternatively, some may find it easier to use a program, either downloadable or in-browser, which will allow them to have a live view of their character on a three dimensional model as they are editing the skin. For example, programs may further assist players by providing them with a wide variety of pre-made selections (such as hats, boots, sweaters, etc.), to give the skin creator exactly what they want, even if the creator has little to no artistic skill.

After making a custom skin, either by using a skin editor or by editing the file directly, one will still need to upload the  file at the Skin section of the Profile page on Minecraft.net (found here) before the skin is applied. Other players in multiplayer will also be able to see this skin. Note that players will not be able to see the custom skin if they are not logged in or when playing offline.

''Note: The Java Edition 1.8 templates can be used for pre-1.8 skins on the skin server. Only the top half of the image is used, e.g. not the individual arms and legs on the bottom, and no overlay on any layer except the head. If the skin is for Java Edition 1.7, the old system must be used exactly.''

There can be up to 3.06×1023,581 unique Minecraft skins.
