zer0
by donrkebab
zer0 is a Fabric client mod that removes cloud rendering, atmospheric fog and dynamic lightmap updates to reduce rendering work on Minecraft 26.1.2.
What it does
The mod turns off three parts of the visual pipeline. The cloud rendering pass is bypassed entirely, so cloud geometry is no longer saved or drawn. The fog renderer is overridden to clear atmospheric fog, which gives a view with no haze across the render distance. Dynamic lightmap recalculation is also skipped, which stops the light values from being rebuilt every frame.
The changes are made through Mixin hooks into the rendering code, targeting these passes directly rather than adjusting their settings. The mod is aimed at players who want higher frame rates and a less cluttered view, and it reduces the non-essential graphics work the GPU and CPU would otherwise do. Zer0 requires Fabric API and has no other external dependencies, and its configuration menus do no background processing.
Key features
Cloud rendering removed
The cloud rendering pass is bypassed completely, so no cloud geometry is saved or drawn.
Fog cleared
Atmospheric fog is overridden and cleared, so distant terrain stays visible across the render distance.
Lightmap updates skipped
Dynamic lightmap recalculations are bypassed, so light values are not rebuilt every frame.
Mixin-level targeting
Each pass is changed at the rendering code level, removing its overhead instead of lowering a graphics setting.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Higher frame rates
Players who want the highest possible frame rate can drop the cloud, fog and lightmap passes to free GPU and CPU time.
Clutter-free view
Players who prefer a plain sky and unobstructed distance can use the mod to remove the atmospheric effects.
Who it’s for: Client players on Minecraft 26.1.2 who want maximum frame rates and a clutter-free view. The mod is client-side only, so servers do not need it.
How it compares

Environmental Fog Disable is client-side only on Fabric and NeoForge for 1.21.6 – 26.3 under the MIT License, but it is not open source. Zer0 covers only 26.1.2 and is not open source.
