The most chaotic Minecraft game drop, Chaos Cubed, has finally arrived on Java Edition. This update adds sulfur caves, the Overworld’s fourth cave biome, the sulfur cube, a mob with its own rules of physics, two new building block sets, and much more.

The sulfur cube is the main attraction of the Chaos Cubed game drop. You can feed various blocks to this mob, and depending on the block type, it gains unique abilities. For example, feeding it TNT turns it into a TNT block with a long fuse, an oak log makes it bouncy and fast, while blue ice makes it extremely fast but not bouncy.

You can find this unusual mob only in sulfur caves. These caves are easy to locate, as they often generate beneath sulfur springs on the surface. Sulfur caves are also home to sulfur and cinnabar blocks, the two new building block sets added in the Chaos Cubed update.

Minecraft 26.2 also introduces several other features, including the Friends List tab, a new music disc, and various technical changes such as experimental Vulkan support. Read the full changelog below for more details.

  • Each archetype is characterized by the speed of the Sulfur Cube when hit, how bouncy it is when colliding with blocks and collidable entities, as well as its ground friction, air drag, and if it floats in liquids
  • There are the following archetypes:
  • Regular: medium speed, medium bounciness, medium ground friction, and low air drag
  • It is buoyant
  • Used when absorbing loose mineral and soil blocks
  • Bouncy: fast speed, high bounciness, medium ground friction, and low air drag
  • It is buoyant
  • Used when absorbing wooden blocks
  • Slow Bouncy: slow speed, high bounciness, medium friction, and medium air drag
  • Used when absorbing stone-like blocks
  • Slow Flat: slow speed, low bounciness, medium ground friction, and medium air drag
  • Used when absorbing metal blocks
  • Fast Flat: fast speed, low bounciness, medium ground friction, and low air drag

  • This cloud spreads across adjacent water with a maximum radius of 3 blocks
  • Can be crafted from 9 Sulfur blocks
  • When placed above a Magma Block or a Lava Block, and under 1-4 Water source blocks, it creates a geyser

  • Added an “Xbox Settings…” button in Online Options that opens the Microsoft account privacy and online safety settings

Vulkan Support

  • As previously announced, we intend to switch the game from OpenGL to Vulkan
  • Vulkan is not supported by older hardware or drivers – OpenGL will be used as a fallback on those cases
  • The current requirement is Vulkan 1.2 with dynamic rendering and push descriptors, but this requirement may increase or decrease over time
  • This is currently an experimental rendering backend, and may not be as performant or stable
  • Please report any bugs you find with it to the official bug tracker
  • Under Vulkan, we will prefer your dedicated graphics card over any integrated graphics, which is a change from OpenGL
  • You can see which backend is being used in your F3 debug overlay (in the system_specs section)
  • On macOS, we use MoltenVK to translate Vulkan to Metal

“Graphics API” Video Setting

  • This is a new option available in the “Video Settings”
  • There are three values: Default, Prefer Vulkan (Experimental) and Prefer OpenGL
  • “Default” may be changed at our discretion, and we recommend this for all users unless you experience issues and need to change
  • Currently, it is the same as “Prefer OpenGL”
  • “Prefer Vulkan (Experimental)” will attempt to render using Vulkan, but fall back to OpenGL if it doesn’t work
  • Vulkan support is experimental for now, and using it might reduce performance or cause instability on some systems
  • “Prefer OpenGL” will attempt to render using OpenGL, but fall back to Vulkan if it doesn’t work

Startup and Fallback Behavior

  • If the game crashes at startup with “Prefer Vulkan (Experimental)” set, the setting will automatically be changed to “Default”
  • When set to “Default”, the game will still attempt to gather systems information about Vulkan at startup
  • If the game crashes at startup with “Default” set, the setting will automatically be changed to “Prefer OpenGL”
  • With “Prefer OpenGL” set, no interaction will be made with Vulkan in case that causes crashes

Changes in Minecraft 26.2 update

  • Tweaked various mobs hitbox, eye height, and rider positions
  • Hoglins are now considered hostile and do not spawn on Peaceful difficulty
  • Fixed baby Hoglin’s and Zoglin’s left ear texture so it’s properly mirrored
  • Updated the Main Menu background panorama
  • When the game is overwhelmed with particles, instead of removing existing particles in flight, it will now randomly select for particles to render or not render to stay under the particle limit
  • This change is especially visible with a large number of new geyser eruptions
  • As the host of a world, changing the game mode with F3 + F4 or with commands changes the default game mode of the world
  • Upgrading certain worlds from before 26.1 can now be faster
  • Respawning (as a spectator) in a hardcore world no longer turns off the spectators_generate_chunks game rule
  • Removed Touchscreen Mode

Developer’s Note:Touchscreen mode has been poorly implemented and not properly supported for a long time. We are removing this feature in this release. To provide your feedback on this topic, head over to the feedback site.

Minor Tweaks to Blocks, Items and Entities

  • Beds are now slightly more bouncy to match Bedrock
  • When an entity bounces off of a block or other collidable entity, it emits a vibration of frequency 2

Developer’s Note:We have tweaked how Beds and Slime Blocks restitute entity velocity after collisions. For instance, when air drag is removed via the entity attribute, Slime Blocks will now correctly bounce Mobs indefinitely. This may affect player perception of the bounciness of Beds and Slime Blocks.

Sounds

  • Updated sounds for Nautilus jets and Nautilus recovers
  • Updated hurt and death sounds for one of the Chicken’s sound variants

UI

  • Added a Friends button to the Title Screen and the Pause Menu
  • The tooltip for the “Exclusive Fullscreen” video setting now mentions that Adaptive Sync (Nvidia G-Sync, AMD FreeSync) should work when it is enabled and will not work when it is disabled

World Options Screen

  • The host of a world now has access to the “Game Mode” and “Allow Commands” buttons in the World Options screen
  • These buttons are not available in Hardcore

Open to LAN Screen

  • The host of a world can now configure the “Game Mode” and “Allow Commands” values for other players in your world (separate from themselves)
  • These buttons are available under a “Settings for Other Players” header in the Open to LAN screen”

That’s everything new in the Minecraft 26.2 update for Java Edition. As with every major update, it also includes numerous technical changes and bug fixes. If you are interested in those, check out the official 26.2 patch notes for the complete details.
