'''26.4 Snapshot 6''' (known as '''26.4-snapshot-6''' in the [[Minecraft:launcher]]) is the sixth [[Minecraft:snapshot]] for [[Minecraft:Java Edition 26.4]], released on October 27, 2026,<ref>{{Mcnet|minecraft-26-4-snapshot-6|Minecraft 26.4 Snapshot 6|October 27, 2026}}</ref> which adds the [[Minecraft:snow bricks]] block set and the cold [[Minecraft:Sulfur Cube|sulfur cube]] archetype, and fixes bugs.

== Additions ==
=== Blocks ===
'''[[File:Snow Bricks JE1.png|32px]] [[Minecraft:Snow bricks]]'''
* A new kind of brick made of [[Minecraft:snow]].
* Crafted using a 2×2 square of snow blocks.
* Have a [[Minecraft:Snow Brick Slab|slab]], [[Minecraft:Snow Brick Stairs|stairs]], and [[Minecraft:Snow Brick Wall|wall]] variant.
** A [[Minecraft:stonecutter]] cannot be used to craft snow brick slabs, stairs, and walls.
* Snow bricks belong to the Fast Sliding [[Minecraft:sulfur cube]] archetype.
* The correct tool to mine snow bricks is a [[Minecraft:shovel]], and will only drop themselves if mined with one.

'''[[File:Snow Brick Slab JE1.png|32px]] [[Minecraft:Snow brick slab]]'''
* The slab variant of snow bricks.

'''[[File:Snow Brick Stairs (N) JE1.png|32px]] [[Minecraft:Snow brick stairs]]'''
* The stair variant of snow bricks.

'''[[File:Snow Brick Wall (ewU) JE1.png|32px]] [[Minecraft:Snow brick wall]]'''
* Wall variant of snow bricks.

=== General ===
'''[[Minecraft:Sulfur cube archetype definition]]'''
* Added new {{cd|location_based_effects}} field — an optional list of location-based effects.
** The format for each entry is exactly the same as a location-based enchantment effect.
** Level-based values in this definition will always be evaluated with level {{cd|1}}.

'''[[Minecraft:Tag (Java Edition)|Tags]]'''
* Entity type tags
** Added {{cd|#swimming}} for entity types that are considered swimming in water.
** Added {{cd|#flying}} for entity types that are considered flying.
* Fluid tags
** Added {{cd|#swimmable}} for fluids that players can swim in.
* Item tags
** Added {{cd|#sulfur_cube_archetype/cold}} for items that can be placed inside the [[Minecraft:sulfur cube]] that turns it into a cold sulfur cube archetype.

== Changes ==
=== Blocks ===
'''[[Minecraft:Brittle ice]]'''
* Will no longer crack when a [[Minecraft:stray]] is standing on top of it.

'''[[Minecraft:Chiseled packed ice]], [[Minecraft:packed ice bricks]], [[Minecraft:packed ice brick slab|slab]], [[Minecraft:packed ice brick stairs|stairs]], and [[Minecraft:packed ice brick wall|wall]]'''
* All packed ice brick variants now require a pickaxe to drop themselves.

'''[[Minecraft:Ice crystal]]'''
* Has a chance of playing an ambient sound if it has a block of [[Minecraft:packed ice]] below.

=== Mobs ===
'''General'''
* Mobs falling through lava may take slightly less fall damage in some cases.

'''[[Minecraft:Sulfur cube]]'''
* Added the "Cold" archetype, with similar properties to "Fast Sliding" except it is buoyant.
** Used when the sulfur cube absorbs a [[Minecraft:blue ice]] block.
** Floats and replaces water below it with a disk of [[Minecraft:frosted ice]] when it moves, similar to the [[Minecraft:Frost Walker]] enchantment.
*** Will only place frosted ice if the sulfur cube starts its movement while it is on ground.
*** Air blocks above the water block are required for frosted ice placement.

=== General ===
'''[[Minecraft:Data pack]]'''
* The [[Minecraft:pack format]] version is now {{cd|125.1}}.

'''[[Minecraft:Density function]]s'''
* Changed {{cd|gradient}}
** The {{cd|from_coordinate}} and {{cd|to_coordinate}} fields now additionally accept a Vertical Anchor, as long as axis is {{cd|y}}.
* Added {{cd|domain_warp}}
** Samples an input function by applying an offset to each sampled coordinate.
*** Note: if the offsets change rapidly by large amount, performance may degrade significantly. This function should be used sparingly.
** Format: object with fields:
*** {{cd|input}} — density function, the input function to sample.
*** {{cd|offset_x}} — density function, the offset to apply to sampled X coordinates.
**** The result is implicitly truncated to an integer.
**** If not specified, defaults to: {{cd|0.0}}.
*** {{cd|offset_y}} — density function, the offset to apply to sampled Y coordinates.
**** The result is implicitly truncated to an integer.
**** If not specified, defaults to: {{cd|0.0}}.
*** {{cd|offset_z}} — density function, the offset to apply to sampled Z coordinates.
**** The result is implicitly truncated to an integer.
**** If not specified, defaults to: {{cd|0.0}}.
** At least one of {{cd|offset_x}}, {{cd|offset_y}}, or {{cd|offset_z}} must be specified.

'''Launcher metadata'''
* Tweaked default JVM options in the launcher metadata for this version.
** The launcher will thus pass arguments to set the player's JVM heap size based on their system memory, using up to 25% with a maximum of 4 GB.

'''[[Minecraft:Resource pack]]'''
* The version is now {{cd|101.0}}.

'''[[Minecraft:Sound]]s'''
* Added new sound events: {{cd|block.ice_crystal.ambient}}

'''[[Minecraft:Structure pool element]]s'''
* Added optional {{cd|corner_constraint}} field
** Limits the placement of a structure pool element this by sampling a density function at the corners of its bounding box.
** Format: list of objects with fields:
*** {{cd|density_function}} — the density function to sample at the bounding box' corner.
*** {{cd|acceptable_density}} — inclusive range of doubles, a corner's sampled density within this range counts as "inside".
*** {{cd|padding}} — integer between {{cd|0}}, and {{cd|8}}, the padding of the bounding box before sampling its corners.
**** If not present, defaults to {{cd|0}}.
*** {{cd|corners}} — one of {{cd|all}}, {{cd|top}}, or {{cd|bottom}}, which corners to check.
**** If not present, defaults to {{cd|all}}.
*** {{cd|required_corners}} — range between {{cd|1}}, and {{cd|8}}, the number of corners that must be inside {{cd|acceptable_density}} for the check to pass.

'''[[Minecraft:Texture]]s'''
* Block models
** Removed block models: {{cd|block/cube_top}}
* Block sprites
** Added new block textures: {{cd|block/snow_bricks.png}}
