This article is about the current system to customize assets. For other uses, see Texture Pack (disambiguation).
The default textures, with a custom resource pack (Soartex Fanver) in the center.

The resource pack system provides a way for players to customize textures, models, music, sounds, languages, texts such as the end poem, splashes and credits, and fonts, without any code modification.

Java EditionEdit

BehaviorEdit

 
The default resource pack settings.

Resource packs can be placed in the folder resourcepacks within the .minecraft folder. Each resource pack is either a sub-folder or a .zip file within the resourcepacks folder. Once in the folder, a resource pack can be added from the options, where resource packs can be moved between "Available resource packs" and "Selected resource packs". "Selected resource packs" also contain the default assets on the bottom, which cannot be removed.

Resource packs load their assets based on the order of the packs on the list. The bottom-most pack loads first, then each pack placed above it replaces assets of the same name with its assets.

Default resource packsEdit

A resource pack can be bundled with a world by saving it under the name resources and placing it directly in the world's folder. When playing the world, that resource pack appears as the default right above the default resource pack. A default resource pack can also be set on a server by adding a link to a .zip file download after the line resource-pack= in the server properties file. Users can still opt out of using the resource pack or choose not to download it, however.

The old (pre-1.14) textures are available in a resource pack titled "Programmer Art". These textures are not updated when the game receives new textures.

More than one directory for different namespaces may exist under the assets directory.

ContentsEdit

A resource pack is identified by Minecraft based on the presence of the file pack.mcmeta in the root directory, which contains a JSON file with the following information:

  • The root tag
    •  pack: Holds the resource pack information
      •  pack_format: Pack version. If this number does not match the current required number, the resource pack displays an error and required additional confirmation to load the pack. Requires 1 for 1.6.11.8.9, 2 for 1.91.10.2, 3 for 1.111.12.2, 4 for 1.131.14.4, 5 for 1.151.16.1 and 6 for 1.16.21.16.3.
      •  description: Text shown below the pack name in the resource pack menu. The text is shown on two lines. If the text is too long it is truncated.
      •  description: Contains a raw JSON text object that is shown instead as the pack description in the resource pack menu. Same behavior as the string version of the description tag, but they cannot exist together.
    •  language: Contains additional languages to add to the language menu
      • Language code for a language, corresponding to a .json file with the same name in the folder assets/<namespace>/lang.
        •  name: The full name of the language
        •  region: The country or region name
        •  bidirectional: If true, the language reads right to left.

The root directory also contains an optional image called pack.png, which appears as the thumbnail for the pack on the resource pack selection menu.

LanguageEdit

Resource packs can create language files of the type .json in the folder assets/<namespace>/lang. Each file either replaces information from a file of the same name in the default or a lower pack, or it creates a new language as defined by pack.mcmeta.

Each line in the .json file is in the standard json format of "identifier":"name" followed by a comma in case it is followed by another value in the next line. identifier is the name that the game looks for to determine the name for something, and as such it should not be changed. name is the name that is displayed. For example, stone in the default language file is "block.minecraft.stone":"Stone", with block.minecraft.stone being the identifier, and Stone being the displayed name. Blank lines are ignored. The file needs to be valid JSON syntax, meaning it starts with a {, has a comma after every key value pair except the last one, and ends with a }.

Language files need to add only those lines that are changed by the pack. Any names that are not in the pack are loaded from the pack below, or default if no pack changes the names.

ModelsEdit

Main article: Model

Models are files in JSON format with the extension .json, which determine the shape and textures of blocks and items.

Blocks use a block state file from assets/minecraft/blockstates to determine which model is loaded for each variant from the folder assets/minecraft/models/block. Meanwhile, each item has an item model in assets/minecraft/models/item to determine its model, which either loads from a block's model, contains data for its own custom model, or uses the default "flat" or "entity" model.

Models and block states used in packs below the top one are still loaded unless overridden in the top pack, which may cause some textures and models used by the top pack to no longer be loaded.

SoundsEdit

Resource packs load additional sounds with the file type of .ogg. Each sound placed in the pack overrides the sounds from packs below, and packs also contain a file called sounds.json which is placed within assets/minecraft. Unlike most other files in resource packs, sounds.json merges sound information from packs below the top pack, rather than each sounds.json file overriding the previous completely.

TexturesEdit

 
The "missing texture" for invalid or missing textures.

For block or item textures to function, they must have equal width and height (or height that is a multiple of the width if animated); otherwise it appears as a magenta and black checkerboard. For most other textures, the file is stretched to fit the required dimensions.

Most solid blocks turn any transparent area fully opaque. Some other blocks, which have "cutout" transparency (like glass) turn all pixels that are less than 10% opaque fully transparent and all other pixels completely opaque. Every other block renders textures with semi-transparency as-is. All items and any blocks or entities which are semi-transparent by default support semi-transparency.

If a file does not exist in any resource pack, including the default, it appears as a magenta and black checkerboard texture using the colors (
 #f800f8 and
 #000000).

Animation

Block and item textures support animation by placing each additional frame below the last. The animation is then controlled using a .mcmeta file in JSON format with the same name and .png at the end of the filename, in the same directory. For example, the .mcmeta file for stone.png would be stone.png.mcmeta.

  • The root tag
    •  animation: Contains data for the animation
      •  interpolate: If true, Minecraft generates additional frames between frames with a frame time greater than 1 between them. Defaults to false.
      •  width: The width of the tile, as a direct ratio rather than in pixels. This is unused in vanilla's files but can be used by resource packs to have frames that are not perfect squares.
      •  height: The height of the tile in direct pixels, as a ratio rather than in pixels. This is unused in vanilla's files but can be used by resource packs to have frames that are not perfect squares.
      •  frametime: Sets the default time for each frame in increments of one game tick. Defaults to 1.
      •  frames: Contains a list of frames. Defaults to displaying all the frames from top to bottom.
        • A number corresponding to position of a frame from the top, with the top frame being 0
        • A frame specifies a frame with additional data
          •  index: A number corresponding to position of a frame from the top, with the top frame being 0
          •  time: The time in ticks to show this frame, overriding "frametime" above.

If the .mcmeta file does not exist in the pack and the texture does, the game assumes the texture is not animated, rather than loading a .mcmeta file from a pack below that pack. If no .mcmeta file exists for a texture with unequal dimensions, the texture appears as a purple and black checkerboard.

Villagers

Textures from assets/minecraft/textures/entity/villager and assets/minecraft/textures/entity/zombie_villager support a .mcmeta file in JSON format containing additional effects to apply to the hat layer. The file is contained in the same directory as the texture, and has the same name as the texture, except appended with .mcmeta. For example, the file profession/farmer.png can have a properties file called profession/farmer.png.mcmeta

  • The root tag
    •  villager: Contains data for the texture

If the .mcmeta file does not exist in the pack and the texture does, the game loads the default settings, rather than loading a .mcmeta file from a pack below that pack.

Colormaps

Colormaps are 256×256 pixel images which tell the game which color to use in each biome. They are located in assets/minecraft/textures/colormap. The game contains two colormaps, foliage.png which colors plants such as leaves (except birch and spruce) and vines, and grass.png which colors grass and grass blocks. Colormaps can be disabled on individual blocks by removing the tintindex tag from the block model.

Properties

Textures from assets/minecraft/textures/misc support a .mcmeta file in JSON format containing additional effects to apply to the texture. The file is contained in the same directory as the texture, and has the same name as the texture, except appended with .mcmeta. For example, the file pumpkinblur.png can have a properties file called pumpkinblur.png.mcmeta

  • The root tag
    •  texture: Contains data for the texture
      •  blur: Causes the texture to blur when viewed from close up. Defaults to false
      •  clamp: Causes the texture to stretch instead of tiling in cases where it otherwise would, such as on the shadow. Defaults to false
      •  mipmaps: Custom mipmap values for the texture

If the .mcmeta file does not exist in the pack and the texture does, the game loads the default settings, rather than loading a .mcmeta file from a pack below that pack.

TextsEdit

Three .txt files in UTF-8 format exist in assets/minecraft/texts which are used by the game to determine the text to display.

The file end.txt contains the text of the end poem, using formatting codes to apply the colors to the two speakers, and with the text PLAYERNAME being replaced with the player's name. After that file is shown, the contents of credits.txt are shown.

The file splashes.txt contains lines of text separated using line breaks to determine the splashes to display in-game. Any splash can be replaced with different text.

FontsEdit

A font file is a JSON file located at assets/<namespace>/font within a resource pack and contains a list of providers that each tie a character set to a resource location along with some extra information. The default font is defined by the font minecraft:default while the default font used by enchantment tables is defined by the font minecraft:alt. The resource locations given in font providers should also include the file extensions.

  • The root tag
    •  providers: A list of providers that are merged onto this font.
      • A font provider. The contents depend on the value of the "type" tag.
        •  type: The type of the font provider. Can be one of the following:
          • bitmap: A bitmap font.
            •  file: The resource location of the used file, starting from assets/<namespace>/textures.
            •  height: Optional. The height of the character, measured in pixels. Can be negative. This tag is separate from the area used in the source texture and just rescales the displayed result. Default is 8.
            •  ascent: The ascent of the character, measured in pixels. This value adds a vertical shift to the displayed result.
            •  chars: A list of strings containing the characters replaced by this provider, as well as their order within the texture. All elements must describe the same number of characters. The texture is split into one equally sized row for each element of this list. Each row is split into one equally sized character for each character within one list element.
          • legacy_unicode: A legacy unicode font. This format is deprecated and only prioritized when the "Force Unicode Font" option is turned on.
            •  sizes: The resource location inside assets/<namespace>/font describing a binary file describing the horizontal start and end positions for each character from 0 to 15. The file extension of the target file should be .bin.
            •  template: The resource location inside assets/<namespace>/textures that leads to the texture files that should be used for this provider. The game replaces %s from the value of this tag with the first two characters of the hex code of the replaced characters, so a single provider of this type can point into multiple texture files.
          • ttf: A TrueType font.[more information needed]
            •  file: The resource location of the TrueType font file within assets/<namespace>/font.
            •  shift: The distance by which the characters of this provider are shifted.
              • Left shift
              • Downwards shift
            •  size: Font size to render at.
            •  oversample: Resolution to render at.
            •  skip: String or array of strings to exclude.
Default textures

The texture files of the default fonts contain a grid of white characters, which are automatically colored by Minecraft as needed in-game. The character sizes are automatically determined based on the last line of pixels containing any alpha value. Due to the way fonts are detected, filling the background of a character with a color containing a 5% alpha background causes the full width to render without having a visible background to the character.

  • Glyphs 0x20 (space) through 0x7E (tilde) display the standard ASCII characters,
  • Glyphs 0x7F through 0xFF display the Code page 437 characters.

The default texture is located in assets/minecraft/textures/font/ascii.png

The default texture used when displaying the enchanting "alien font" is assets/minecraft/textures/font/ascii_sga.png

Texture sheetsEdit

Minecraft generally does not store multiple different textures on sheets and instead stores them on separate files. Two current exceptions are map icons[1] and experience orbs as well as minecarts.[2]

ShadersEdit

Shaders are GLSL files that are compiled when loaded. They are used to modify the look of the game and come in two varieties, vertex and fragment. The vertex shaders modify the positions of individual vertices and are most often used to create waving foliage and water. Fragment shaders are applied to every pixel and can be used to add effects like bloom, god rays, and blur. The folder contains JSON files which link to the vertex and fragment shaders and provide info about them. If any error occurs when loading the shaders, the resource pack is unloaded and fabulous graphics are turned off.

"Post" JSONEdit
  • The root tag
    •  targets: A list of render targets.
    •  passes: A list of passes.
      • : A render pass.
        •  name: The name of the render pass.
        •  intarget: The target to use as an input.
        •  outtarget: The target to output to.

          • An auxiliary target.
            •  name: The auxiliary target's name.
            •  id: The auxiliary target's id.
"Program" JSONEdit
  • The root tag
    •   blend: Settings for OpenGL blending. [verify]
      •   func: Operator to be used when blending. [verify]
      •   srcrgb: Source, most likely used as sfactor parameter of glBlendFunc.

Bedrock EditionEdit

Main article: Add-ons

Similarly to skins, resource packs can be bought or made in Bedrock Edition. As of Alpha 0.15.0, iOS users can download resource packs on the system itself with the .mcpack and .mcworld file names. When these files are opened, they are automatically imported into the game without any need for file system access.

HistoryEdit

Java Edition
1.6.113w24aAdded resource packs, replacing the functionality of texture packs. Minecraft Texture Ender is available from Mojang to automatically convert 1.5 compatible texture packs to resource packs.
1.6.2reuploadFixed distorted font when HD font is used.[3]
1.7.213w36aAdded the ability to apply multiple resource packs at once.
13w42aMoved files from assets/minecraft/music to assets/minecraft/sounds/music and files from assets/minecraft/sound to assets/minecraft/sounds.
1.7.313w47aThe description value of pack.mcmeta can now be raw JSON text format.
1.7.413w48aRemoved the ability to change the Mojang logo.
1.814w06aAdded the ability to change the block models.
14w07aResource packs can now be bundled with a map.
14w25aThe model format now supports custom item models.
Textures can now be specified for blocks and items.
Added the interpolate tag for animations.
1.8.8preResource packs now display an error if the format number is wrong. At this time, it requires a format number of 1.
1.915w31aChanged format number to 2, due to changes in the model system, such as item tags, multipart, and changes to display tags.
Using resource packs with outdated display tags causes the models to seem abnormally up-scaled and the wielded block cannot be rotated in the hand, along with blocks in the inventory replaced with a 2D texture. This is similar to what happens when a model has no display tags. See here for an example.
1.1116w32aResource packs version number changed to 3, due to the change that all files should have lowercase letters.
1.1317w43aThe default resource pack can now be moved up and down, just like other resource packs.
17w48aChanged format number to 4, due to The Flattening.
1.1418w45aAdded "Programmer Art – The classic look of Minecraft" to the resource pack menu, due to the old textures being replaced by new ones in the Texture Update.
19w06aSignificantly improved resource pack loading speed.[4]
Particles textures are now plot into individual files.
19w07aPainting textures are now split into individual files.
19w08aStatus effect textures are now split into individual files.
1.15Pre-release 1Changed format number to 5, due to texture mechanic changes in earlier snapshots.
1.16.2Release Candidate 1Changed format number to 6, due to changes to wall blocks made in 1.16 according to MC-197275.
Pocket Edition Alpha
0.15.0?Added the first custom in-game resource packs, Plastic and City.
Bedrock Edition
1.10.0beta 1.10.0.3Resource packs are now separate from world templates and can be updated independently in existing worlds.

TriviaEdit

 
The world that the pack.png screenshot was taken in, loaded in Alpha v1.2.2.
  • The old pack.png file was screenshotted from Alpha v1.2.2, the seed being 3257840388504953787.[5]
    • The screenshot was taken approximately at X=49.16, Z=0.72, facing RX=-119.23, RY=-8.297.
