Minecraft Snapshot 25w07a

Frogday on a Thursday, who thinks of that?! In this week's snapshot we are updating trades for wandering traders and cartographers. We have also introduced new, biome-based spawn rules for sheep. It's time to go out and explore the world! Mojang's bug-tracker Mojira is migrating to the cloud and during the process bug reporting is unavailable. The new platform will soon be up and running, ready for players to log in, create accounts, and most importantly – report bugs! During the downtime, try to keep the bug alive and report it once Mojira is back!

Shaders & Post-process Effects

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.

• Shader program definitions for core shaders and post-processing effects as JSON files have been removed
• The shader programs themselves are still available and can be overridden
• The post-processing effects are still configurable as JSON

Post-process Effect Definitions

• The field program was replaced with vertex_shader and fragment_shader
  • <namespace>:<path> will resolve to assets/<namespace>/shaders/<path>.<vsh|fsh>
• type is now a required field for each uniform
  • Possible values are currently int, ivec3, float, vec2, vec3, vec4, matrix4
• values in each uniform is now optional
  • Leaving it unset is not recommended and is used for runtime configuration of the blur effect
• Leaving a uniform unspecified results in undefined behavior, you must specify each one that will be used by the shaders

Item rendering

Item Display

• firstperson_lefthand and thirdperson_lefthand transforms are now rendered the same as when held in hand

Item Entity

• When on ground, model size is now taken into account when determining hovering motion
  • That means that models should never clip into the block below, no matter what size they are
• Positioning of items in an item stack on ground now depends on model size and model type
  • If model depth (Z coordinate) is below 1/16th of a block, item is rendered as flat stack of items
  • Otherwise model is rendered as a cluster of items offset in all directions around center
  • Previously, flat stack rendering happened only for models with builtin/generated parent
