Greedy Meshing Mod
A client-side Fabric optimization mod that merges identical adjacent block faces into larger quads, reducing the total vertex count for better GPU performance.
Features
- Automatic merging of opaque full-cube block faces
- Custom terrain shaders for correct texture tiling on merged faces
- Aggressive Greedy (Absolute) option. It merges across ambient-occlusion boundaries for even fewer quads, at the cost of slightly coarser lighting
- Greedy Water option (VERY experimental). Merges flat still-water surfaces (open oceans, lake interiors) into larger quads. Shorelines and flowing water are unaffected. Not supported on VulkanMod, works kinda okay on Sodium and Vanilla.
- Sodium compatible
- VulkanMod compatible (1.21-1.21.5, 1.21.9-1.21.11, 26.1-26.1.2; 1.21.6-1.21.8 not available, VulkanMod was never released for those)
- Sable compatible, the sub-level geometry no longer double-darkens with greedy meshing on
- Works with Minecraft 26.2's native experimental Vulkan rendering backend
- Debug wireframe and split-screen comparison mode
- In-game config screen (requires Cloth Config + Mod Menu)
Supported Versions
| Minecraft | Loader |
|---|---|
| 1.21 - 1.21.11 | Fabric |
| 26.1 - 26.2 | Fabric |
Performance
Performance gains vary depending on your hardware and world. If your GPU is already underutilized (high FPS), the improvement may be minimal. The mod benefits most on lower-end GPUs, higher render distances, and worlds with large flat surfaces of the same block type (e.g. superflat, underground caves, large builds).
Known Limitations
- Experimental - some mods that modify chunk rendering or terrain shaders may be incompatible. Disable via config if issues occur.
- Shader packs (Iris/OptiFine) are not fully supported. The mod falls back to face-culling-only mode.
- Lighting on large merged surfaces may look slightly different from vanilla.
