Greedy Meshing Mod

The mod is a client-side Fabric optimization that works on chunk rendering. It combines opaque full-cube block faces that share a texture and lighting, so the renderer sends fewer, larger quads to the GPU. Custom terrain shaders keep textures tiled correctly across the merged faces. Sodium is compatible, and the mod is supported with VulkanMod in the version ranges that VulkanMod covers.

Two optional settings extend the merging. The Aggressive Greedy Absolute setting goes further by merging faces that sit on either side of ambient-occlusion boundaries; the result is fewer quads, though lighting comes out a little less precise. Greedy Water is experimental and merges flat still-water surfaces such as open oceans and lake interiors, while shorelines and flowing water stay unchanged. Distant Horizons is compatible, and Sable is compatible with sub-level geometry, although that combination can double-darken with greedy meshing.

Fabric API is required. Cloth Config API and Mod Menu are optional. The mod runs on Fabric for 1.21 – 26.3 across 17 release versions, with the latest file 0.6.1+26.3 for 26.3, and it is released under the MIT License as open source. Source code and an issue tracker are public.
