Minecraft:Java Edition 26.4 Snapshot 2

26.4 Snapshot 2 (known as 26.4-snapshot-2 in the Minecraft:launcher) is the second snapshot for Minecraft:Java Edition 26.4, released on September 29, 2026,<ref>Template:Mcnet</ref> which fixes bugs, brings changes to render distance fog, and redesigns the Minecraft:debug screen.

Additions

Template:Cd
- Determines whether the sky occluder is enabled for the environment. The sky occluder will occlude the sky box up until a certain angle with fog color with a smooth occlusion border.
  - Value type: boolean
  - Default value: Template:Cd for the Overworld, Template:Cd for the Nether and the End.
  - Interpolated: no

Added Template:Cd
- Checks if the height of the position is below a given heightmap value.
- Format:
  - Template:Cd: Heightmap type to compare origin against.

Added sky_occluder.vsh and sky_occluder.fsh shaders which are used to occlude the sky box up until the certain angle with fog color with a smooth occlusion border.

The items in the debug overlay (Template:Keys by default) are now sorted into categories and have been made easier to read and understand.

Render distance edge fog now reduces the opacity of objects at the edge of loaded chunks, rather than fading them into an opaque, constant color (which previously made them stick out strongly from the sky).

screenquad.vsh was renamed to screentriangle.vsh since it was actually representing a single triangle for a while now.
Removed OIT (Order-Independent Transparency, controlled by "Improved Transparency" video setting) support from the clouds.fsh, since it is now used to render clouds when OIT is off and to render clouds to an offscreen target when OIT is on.
Added blit_clouds.fsh shader with OIT support that renders clouds from an offscreen target to OIT targets.

When "Improved Transparency" is on, sky background and clouds that are behind the terrain are now blended into the terrain render distance fog making the boundary between the sky and the terrain invisible.
In the Overworld, the bottom half of the skybox is now occluding the celestial objects such as the Minecraft:sun, the Minecraft:moon and the stars.
