Minecraft snapshot 25w19a patch notes: Better rainy fog, improved projectile targeting, and more

Mojang has released Minecraft Snapshot 25w19a for Java Edition. This new snapshot doesn't introduce any brand-new features but instead improves the game's fog effects during rain and updates projectile targeting mechanics.

Players who have used Minecraft shaders may be familiar with how foggy the world appears during rain. Minecraft will now showcase a similarly thick fog during rain in the Overworld. In addition to a better fog system, Mojang has also made some technical adjustments to how fog works. These changes are likely intended to prepare Java Edition for the upcoming Vibrant Visuals feature, the official vanilla shaders for Minecraft.

Without further ado, let's dive into the complete Minecraft Snapshot 25w19a to explore all the changes and bug fixes.

Minecraft snapshot 25w19a patch notes: All you need to know

Changes

• Projectiles target tolerance margin now changes over time
• Fog was tweaked for improved atmospheric perspective
• It now becomes foggier when it rains
• The test framework will no longer try to restart running tests after a server restart

Projectile Targeting

• Projectiles now have a target tolerance margin that changes over time
• Previously, all projectiles had a fixed 0.3 blocks target tolerance margin
• Now, all projectiles start with no margin for the first two ticks of their flight
• After that, the target margin will expand by 0.05 blocks per tick until it reaches the previous 0.3 blocks margin
• This allows for better precision close to the shooting player or entity, while still allowing for some collision leeway when the projectile is further away

Shaders & Post-process Effects

Shader fog changes

• The fog is now split into environmental and render-distance-based
• Previously both those concepts were mixed in the same uniforms
• Environmental fog is supposed to represent the "fogginess" of the environment the player is in: lava, water, and now also atmosphere
• Render distance fog is supposed to obscure the border of visible terrain
• Environmental fog uses spherical distance to determine its intensity, render distance fog uses cylindrical distance
• The resulting fog value for any given vertex is the maximum of both

Fog Uniform Block

• FogStart was renamed to FogRenderDistanceStart and now represents the render distance fog start
• FogEnd was renamed to FogRenderDistanceEnd and now represents the render distance fog end
• FogEnvironmentalStart is new and represents the start of environment-based fog
• FogEnvironmentalEnd is new and represents the end of environment-based fog
• FogShape was removed. Render distance fog is now cylindrical and environmental for is spherical

Sound Events

• block.dried_ghast.hit has been removed
