Minecraft Java Edition 26.3

Wilderness Bound is out now in Minecraft Java Edition! Pack your supplies and set off on an expedition into the dappled forest where the trails end and adventure begins. Seek out abandoned camps, build outposts among the poplar trees, sleep under the stars on straw beds, and share campfire stories atop cushions. Just remember that the wilderness rewards the prepared - and maps are lighter than regrets!

Happy camping!

Order-independent Transparency (OIT)

• Generally, translucent surfaces need to be rendered back-to-front to avoid visual issues
  • In order to do so, the translucent geometry has to be sorted before rendering
  • This is very expensive and even with perfect sorting of individual triangles, intersecting triangles are not possible to render correctly
• Before this release, the "Improved Transparency" video setting attempted to mitigate translucency-related visual issues
  • It did this by rendering different types of translucent objects (entities, particles, water, etc.) to different textures that were later combined to create the final image
  • This allowed us to fix some of the issues with some performance impact
  • However, it introduced some other less noticeable issues
• Now, the "Improved Transparency" video setting will instead enable a new order-independent transparency algorithm (which we will refer to as OIT)
  • This makes it possible to render translucent objects in any order without sorting
  • It fixes all existing major translucency-related visual issues (such as certain objects disappearing when viewed through translucent objects)
  • However, the algorithm is an approximation, and so it introduces some new minor visual artifacts (such as the color of clouds being somewhat incorrect when viewed through multiple layers of translucent surfaces)
• We expect OIT to have a higher performance impact than the previous implementation of "Improved Transparency"
• When "Improved Transparency" is turned off, the behavior hasn't meaningfully changed and the game will still prioritize performance over correctness while sorting geometry as necessary

Developer's Note: Special thanks to Rubén Osorio López, Jozufozu, and the Minecraft modding community in general for sharing the information that helped us to deliver this.

Debug Overlay

• The debug overlay now supports a separate GUI scale from the rest of the game
  • This is customizable through the Debug Options screen, F3 + F6
  • The default scale is "Auto", which tries to stay at a higher resolution than normal
  • Another option is "Unchanged", which matches your regular GUI scale
  • The rest of the options work the same as in the normal "GUI Scale", controlling the scale directly
• Added a "player_speed" debug entry that displays the speed of the player in blocks per tick
• The debug overlay now shows the display refresh rate

• Loot table types that have a dedicated registry now support registry element and tag references
  • This means that the majority of fields of such types that previously accepted single elements will now accept either a namespaced ID or an inline value, while fields that previously accepted lists can now accept an inline value, a single namespaced ID, a list of namespaced IDs, a list of inline values, or a hash-prefixed tag ID
  • Affected types:
    • minecraft:advancement
    • minecraft:item_modifier
    • minecraft:loot_table
    • minecraft:context_int_provider
    • minecraft:context_float_provider

• The following Block State fields have been renamed
  • Name is now id
  • Properties is now properties
• The default Block State of a Block can now be referred to in a compact form directly by the Block id

Commands

Added posteffect

• Allows adding or removing "post effects" to players
• These are postprocessing shaders that are applied to the player's screen, after the game has finished normal rendering
• Post effects exist on the client (in resource packs), not the server – the server cannot know if one will actually apply
• Post effects themselves were already part of the resource pack format, but only a few hardcoded ones were available to use

Developer's Note: This now makes custom shaders fully available to use from resource packs, but please be aware that shaders are still subject to be changed at-will, and the features involved (the command, post effects, or shaders) may be redesigned in the future.

Syntax:

• /posteffect add <player> <posteffect> - adds the post effect to the player, if it doesn't already exist
• /posteffect clear <player> - removes all post effects from the player, if any exist
• /posteffect list <target> - lists all post effects applied to the player, if any exist
• /posteffect remove <player> <posteffect> - removes the post effect from the player, if it exists

Changes to publish

• The gamemode argument has been removed
  • Instead, the default game mode of the world should be set using the defaultgamemode command or the Game Mode button in the World Options screen, while player-specific game modes should be set using the gamemode command

Added compute

• Evaluates minecraft:context_int_provider and minecraft:context_float_provider values in various contexts
• In all contexts, origin is set to the current command context position, while this entity is set to @s
• If the evaluation fails (for example due to division by zero), this command will fail

Syntax:

• /compute <target> integer <int_provider> OR
• /compute <target> float <float_provider> [<scale>], where:
  • <target> - one of:
    • default - runs the provider in the minecraft:command_compute_default context, where only common arguments (position and this entity) are available
    • block <pos> - runs the provider in the minecraft:command_compute_position context, where block state and block position are set based on the block at position <pos>
    • entity <entity selector> - runs the provider in the minecraft:command_compute_entity context, where target_entity is set to the selector result
  • <int_provider> - either an element of the minecraft:context_int_provider registry or an inline value
  • <float_provider> - either an element of the minecraft:context_float_provider registry or an inline value
  • <scale> - optional scale value, defaults to 1.0
    • The final result will be multiplied by <scale> and rounded towards negative infinity

Changes to data

• Added new source to /data modify ... append|insert|merge|prepend|set called compute
• It evaluates a minecraft:context_int_provider or minecraft:context_float_provider value and then provides the result either as an integer or a float tag
• Example: /data modify storage foo bar set compute entity @n[type=minecraft:armor_stand] integer {type:score,target:{type:context,target:target_entity},score:baz}

Syntax:

• compute <target> (integer <int_provider> | float <float_provider>), where the syntax of target, int_provider, float_provider is the same as in the /compute function
  • Note: unlike /compute, there is no scale, since the result is directly stored as a float, instead of being returned from the command as an integer

Changes to give

• When the amount of items passed to the give command is above the limit, the command will now signal an error instead of just printing an error message and returning 0

Changes to tellraw

• The nbt component in a raw chat message will only be resolved up to 64k times

Changes to tick

• The following subcommands will now signal an error instead of just printing an error message and returning 0:
  • tick step
  • tick step stop
  • tick sprint stop

Changes to team

• The result of the team join and team leave subcommands now reflects the exact count of entities that have joined or left (i.e. excluding entities for which teams have not changed)

Changes to item

• Now takes a slot source as an argument in place of anywhere a slot was previously used
  • It will be evaluated with the minecraft:command_slot_source loot type
  • Can be a slot source in either inline or reference form
  • Can be a slot source targeting multiple slots
  • The replace sub-command has new semantics:
    • The contents of each destination slot are replaced with the corresponding source item one by one in the order they are provided by the slot source
    • When there are more destination slots than there are source items, the remaining slots are ignored
      • Example: replace [12345] with (ABC) → [ABC45]
    • When there are fewer destination slots than there are source items, the remaining items are ignored
      • Example: replace [123] with (ABCDE) → [ABC]
  • String notation slot ranges in the form <slot_type> or <slot_type>.<slot_number> are still permitted
    • Can be a single slot, such as armor.chest
    • Can be multiple slots, such as container.*
    • Acts as shorthand for a minecraft:slot_range slot source using that slot range
      • Example: hotbar.4 is the same as {type:"minecraft:slot_range",slots:"hotbar.4"}
• The entity argument in the from entity item source can now be a selector targeting multiple entities
  • When more than a single entity is targeted, the slots sourced from each are concatenated
• Added new fill and override sub-commands, each with syntax identical to /item replace
  • /item fill
    • Fills each destination slot with a source item
    • When there are more destination slots than there are source items, the items repeat until every slot is filled
      • Example: fill [12345] with (ABC) → [ABCAB]
  • /item override
    • Overrides the contents of each destination slot with the corresponding source item
    • When there are more destination slots than there are source items, the remaining slots are cleared
      • Example: override [12345] with (ABC) → [ABC__] (where _ represents an empty slot)

Changes to execute

• Added new slots condition sub-command
  • Counts the number of slots from the slot source that are present on the targeted block or entity
  • The slot source will be evaluated with the minecraft:command_slot_source loot type
  • Syntax:
    • /execute if|unless slots block <pos> <slot source>
    • /execute if|unless slots entity <targets> <slot source>
• The items condition sub-command now takes a slot source as argument instead of a slot
  • The slot source will be evaluated with the minecraft:command_slot_source loot type
  • Syntax:
    • /execute if|unless items block <pos> <slot source> <item predicate>
    • /execute if|unless items entity <targets> <slot source> <item predicate>

Changes to place

• The feature sub-command now allows inline definition of the Feature

Changes to spreadplayers

• Whether a block is safe to spread a player to is now controlled by the #entities_can_teleport_to block tag

Changes to swing

• When used on a player, the player's attack strength will no longer be reset
• Added a new optional argument to set the swing animation to play
  • Allowed values: none, whack, stab

    • Merges each layer's spawn costs together, overriding the lower layer's spawn costs with the higher layer's if both define the same entity type
• Default: Empty

Added minecraft:gameplay/creature_world_gen_spawn_probability

• Sets the probability to run an iteration in which mobs defined to spawn in the creature mob category will spawn during world generation
• Only Dimensions and Biomes will apply this Environment Attribute
• Format: float with range [0,1)

Removed minecraft:reference

• This condition has become obsolete, as any field that takes a loot condition now accepts (among other things) a namespaced ID to other conditions

Potion Predicates

The minecraft:potion_contents Data Component Predicate has been changed to allow matching on specific potion effects.

The previous predicate format used a list of potion types, the new format allows for more refined matching.

The following fields can be used in any combination, all are optional:

• potions - a list of potion types or a potion tag to match
• effects - a Collection Predicate of mob_effects predicates to match
  • The Collection Predicate format is as follows:
    • contains - a list of mob_effects predicates to match
    • count - a list of options for matching a specific number of mob effect predicates, which follow the same format as the minecraft:effects entity sub-predicate
      • test - the mob_effects predicate to match
      • count - the number of matches required, or with min and max will match a range of counts
    • size - require the mob effects list to have a specific size, or with min and max will match a range of sizes

The mob_effects predicate format is a mapping of effect types to properties of that effect. All fields are optional, only the provided fields will be used for matching:

    {
        "minecraft: <effect type>": {
          "duration": <integer bounds representing a duration in ticks>,
          "amplifier": <integer bounds>,
          "ambient: true/false,
          "visible": true/false
        }
    )

Here is an example of matching on several different effects and criteria:

      "effects": {
        "minecraft:jump_boost": {
          "duration": 3600,
          "amplifier": 5,
          "ambient: true,
          "visible": true
        },
        "minecraft:speed": {
          "duration": {
            "min": 360,
            "max": "3600
          },
          "amplifier: {
            "min": 2
          }
        },
        "minecraft:resistance": {}
      }

All criteria are optional.

Number Providers

• The minecraft:number_provider type has been split into two separate types: minecraft:context_int_provider (integer number providers) and minecraft:context_float_provider (float number providers)

Recipes

Potion Brewing Recipes

Potion brewing recipes are now data-driven. New recipes can be added via data packs, and vanilla recipes may be modified. Brewing recipes use the minecraft:brewing type.

The main contents are:

• input - a potion ingredient with a required item field and an optional potion_contents field using a minecraft:potion_contents Data Component Predicate
• reagent - a potion ingredient with a required item field and an optional potion_contents field using a minecraft:potion_contents Data Component Predicate
• output - item stack, the resulting item

Here is an example of a vanilla recipe:

{
  "type": "minecraft:brewing",
  "input": {
    "item": "minecraft:potion",
    "potion_contents": {
      "potion": "minecraft:water"
    }
  },
  "output": {
    "components": {
      "minecraft:potion_contents": {
        "potion": "minecraft:awkward"
      }
    },
    "id": "minecraft:potion"
  },
  "reagent": {
    "item": "minecraft:nether_wart"
  }
}

Any items may be used in any of the 3 slots, for example:

{
  "type": "minecraft:brewing",
  "input": { "item": "minecraft:bucket" },
  "output": { "id": "minecraft:sulfur_cube_bucket" },
  "reagent": { "item": "minecraft:potent_sulfur" }
}

Cooking Recipes

The cookingtime field of all cooking recipes is no longer optional.

The recipes for Smokers and Blast Furnaces now use the same cooking time in their data definition as their Furnace counterparts.

The cooking time speedup is now done through the minecraft:cooking/speed_default Number Provider used by the furnace fuel components.

Custom Smoker and Blast Furnace recipes should be updated accordingly, by setting cookingtime to twice the previous value.

If a custom cooking recipe was previously relying on the default cookingtime value, 200 can be used to maintain the same timing.

The spawn_target field has been updated to allow use of any Density Function, instead of just a subset of those defined within the noise_router field.

The suitability of a candidate spawn position is determined by evaluating, in some arbitrary n-dimensional space, the squared Euclidean distance to a set of target hypercubes.

For example, one axis might be temperature and the second erosion - and suitability determined by distance to the square between temperature=0.1, erosion=0.2 and temperature=0.3, erosion=0.5. This would prefer any candidate spawn within those ranges equally, while penalizing candidate spawns very far out of that range.

Format: list of target hypercubes

• Target format: map between Density Function ID and a range on that axis:
  • Range is specified as one of:
    • Float, an exact target value
    • Array of 2 floats, a range of target values in form [min, max]
    • An object with fields:
      • min - float, the minimum value of the target range
      • max - float, the maximum value of the target range

Material Rules

Material Rule Registry

A new data-driven registry has been introduced, loaded from data/<namespace>/worldgen/material_rule/<id>.json.

Elements in this registry define a pipeline for selecting what base block to place in the world at a given position.

The format is identical to that which was formerly written in the surface_rule field within Noise Settings files, with the following extensions:

• Material Rules can now be specified either inline (as previously), or as an ID reference to an element in the worldgen/material_rule registry
• Material Conditions can also now be specified as an ID reference to an element in the worldgen/material_condition registry

Material Condition Registry

A new data-driven registry has been introduced, loaded from data/<namespace>/worldgen/material_condition/<id>.json.

Elements in this registry define a condition that can be referenced within a Material Rule pipeline (e.g. testing biome or surface depth).

The format is identical to that which was formerly written within the condition Material Rule type, with the following extension:

• Material Conditions can also now be specified as an ID reference to an element in the worldgen/material_condition registry

Added minecraft:ore_vein

• Format: object with fields:
  • ore_block - Block State, the ore block to place
  • raw_ore_block - Block State, the raw ore block to place
  • filler_block - Block State, the filler block to place
  • raw_ore_chance - float between 0 and 1, the probability for a raw_ore_block to be placed instead of an ore_block
  • density - Density Function, the probability between 0 and 1 for the ore vein to replace a block
    • If 0 or lower, no block will be replaced
  • richness - Density Function, the probability between 0 and 1 for ore_block or raw_ore_block to be placed (as opposed to filler_block)
    • If 0 or lower, all blocks will be filler_block
    • If 1 or greater, no blocks will be filler_block
  • filler_gap - Density Function, acts as an override to richness: if positive, filler_block will always be placed

Noises

The format of Noises (defined in the worldgen/noise registry, or inline in noise-based Block State Providers) has been updated.

Noises define a fractal Brownian motion (fBm) configuration with the following properties:

• Produces output values (approximately) fitting a normal distribution

• Unless otherwise specified, fits the output amplitude to [-1; 1]

  • Due to the normal distribution, in practice this means that 99.7% of all samples will fit in that range - but values may still be encountered outside of this range

• Parameterized by persistence=0.5, lacunarity=2.0

  • i.e. between each octave, the amplitude is halved and the frequency doubled

• Has stable seeding such that an octave can be boosted, muted, or added without affecting the rest of the octaves

• Renamed firstOctave to base_octave

• Added base_amplitude - positive float, a scale factor to apply to the noise output

  • If not specified, defaults to 1.0

• Added octave_count - integer between 1 and 32, the number of octaves to sample

• Added normalize - boolean, or "legacy", controls how the output amplitude should be normalized

  • If true, base_amplitude is the expected amplitude of the output (i.e. 99.7% of all samples in [-base_amplitude; base_amplitude])
  • If false, base_amplitude is the amplitude of the first octave
  • If "legacy", inherits the same normalization behavior as expressed by the previous format
    • This would generally fit to a range smaller than expected
  • If not specified, defaults to true
  • Note: normalization is not affected by the amplitude_modifiers field - as such, modifying the amplitude of a single octave will not affect the amplitude of others

• Renamed amplitudes to amplitude_modifiers - list of floats, a scaling factor to apply to each octave

  • The number of elements in this list must match octave_count
  • As described above, this scaling factor bypasses normalization and will affect the output amplitude
  • This field is no longer required - if not specified, defaults to all 1.0

Density Functions

• Density Functions and noises are no longer evaluated with double-precision floating point values, but instead with single-precision
  • This affects all intermediate steps, not just the final result

Developer's Note: _We are aware that the details of floating point rounding have been used in some Data Packs, and this change may affect specific configurations. We have introduced alternatives for the use-cases that we are aware of, but please do share with us on feedback.minecraft.net or in the feedback Discord if you encounter use-cases that are no longer possible to support.

Item Models

• Added optional shade_direction_override to block model elements
  • Accepted values are cardinal directions (down, up, north, south, west, east)
  • When set, this overrides directional shading for the element regardless of face orientation
• Removed shade from block model elements
  • Use shade_direction_override: "up" to get the previous shade: false behavior

Tint Sources

• Removed minecraft:map_color
  • The minecraft:map_color component it read no longer exists

Shaders & Post-process Effects

• terrain.vsh and terrain.fsh shaders are refactored to support multi-draw
• Some of the members in Globals and DynamicTransforms are shuffled to use less memory for those uniform blocks

Developer's Note: Although it is possible in Resource Packs, overriding Core Shaders is considered as unsupported and not an intended Resource Pack feature. These shaders exist as part of the internal implementation of the game, and as such, may change at any time as the game's internals evolve. We understand that overriding Core Shaders is used for very cool Resource Pack features, many of which lack supported alternatives. We would like to provide better, supported alternatives in the future.

Order-independent Transparency (OIT)-related Shader Changes

• Added new shaders to support order-independent transparency:
  • core/blit_depth.fsh
  • core/oit_composite.fsh
  • core/oit_depth_bounds_cull.fsh
  • include/oit.glsl
  • include/oit_add_transmittance.glsl
  • include/oit_common.glsl
  • include/oit_depth_bounds.glsl
  • include/oit_depth_sample.glsl
  • include/oit_sample.glsl
• Extracted the texture sampling logic from core/terrain.fsh into include/texture_sampling.glsl
• Renamed the following core shaders:
  • core/rendertype_clouds.vsh → core/clouds.vsh
  • core/rendertype_clouds.fsh → core/clouds.fsh
  • core/rendertype_world_border.vsh → core/world_border.vsh
  • core/rendertype_world_border.fsh → core/world_border.fsh
• Updated core shaders to support order-independent transparency
  • Introduced new defines:
    • OIT - If present, indicates that OIT is enabled
    • OIT_DEPTH_BOUNDS - If present, indicates that the depth bounds pass is being executed
    • OIT_TRANSMITTANCE - If present, indicates that the transmittance pass is being executed
    • OIT_ACCUMULATE - If present, indicates that the accumulate pass is being executed
    • OIT_ALPHA_ONLY - If present, indicates that either the depth bounds or transmittance pass is being executed
    • OIT_ADDITIVE - If present, indicates that the OIT algorithm should emulate additive blending for the executing pipeline
    • OIT_WAVELET_RANK - An integer internal to the OIT algorithm
    • OIT_COEFF_COUNT - An integer internal to the OIT algorithm
    • OIT_COEFF_ATTACHMENT_COUNT - An integer internal to the OIT algorithm
    • RENDERPEARL_DEPTH_IS_ZERO_TO_ONE - If present, indicates that the current rendering backend uses the depth range of [0, 1], it is available globally to all shaders independently of the OIT setting
    • RENDERPEARL_EXPLICIT_DEPTH_INVARIANCE - If present, indicates that an OIT shader should explicitly output a depth value because a device it is running on can produce a slightly different implicit value
    • Affected shaders:
      • core/block.fsh
      • core/block.vsh
      • core/clouds.fsh
      • core/clouds.vsh
      • core/entity.fsh
      • core/entity.vsh
      • core/item.fsh
      • core/item.vsh
      • core/particle.fsh
      • core/position_color.fsh
      • core/rendertype_beacon_beam.fsh
      • core/rendertype_clouds.fsh
      • core/rendertype_crumbling.fsh
      • core/rendertype_entity_shadow.fsh
      • core/rendertype_lightning.fsh
      • core/rendertype_lines.fsh
      • core/rendertype_world_border.fsh
      • core/terrain.fsh
      • core/terrain.vsh
      • core/text.fsh
      • core/world_border.fsh
      • core/world_border.vsh
• Removed the old transparency post chain:
  • post_effect/transparency.json
  • shaders/post/transparency.fsh

New Core Shaders

• core/integrate_depth.fsh was added and is used to integrate the "3d hud" and always-on-top gizmo depth buffers into the main depth buffer

Removed Core Shaders

• core/text_background.fsh and core/text_background.vsh were removed and text background in Text Display Entities is now rendered using the text shaders

Shader Compilation Changes

• Shaders are now compiled by ShaderC when using OpenGL as well, identically to when using Vulkan
• Shader includes are now handled by ShaderC using #include instead of #moj_import
• Shader inputs and outputs must have a location specified in shader source
  • Vertex input names must still match expected names
  • Vertex outputs are matched to fragment inputs solely by location, the name is now ignored
• Introduced new define RENDERPEARL_INSTANCE_INDEX_INCLUDES_BASE_INSTANCE - A boolean indicating if gl_InstanceIndex follows Vulkan or OpenGL (gl_InstanceID) semantics

Developer's Note: Vertex inputs in previous versions using OpenGL were not allowed to specify a location. Compatibility can be preserved by only specifying locations when the "VULKAN" macro is defined.

Developer's Note: Vertex outputs and fragment inputs in previous versions were matched based on name alone. Compatibility can be preserved by continuing to use identical names.

Always-on Post Effect Support

• A resource pack can now define a minecraft:end_of_frame post effect
• It will be applied before other post effects, including the ones enabled by the new posteffect command
• This post effect is always on as long as the resource pack is loaded, and cannot be controlled by the posteffect command
• As usual with resource pack resources, in case of multiple packs defining this effect, the one from the last resource pack in the list will apply
