About this Mod
GreedyMeshing
GreedyMeshing is a rendering optimization mod for Fabric 1.21.11 that experiments with greedy meshing techniques for chunk geometry generation.
Overview
In vanilla Minecraft, block faces are typically generated individually during chunk mesh building. GreedyMeshing attempts to merge adjacent faces of the same block type into larger quads during mesh generation. This can reduce the number of faces generated for flat or uniform surfaces.
For example, a flat wall made from many identical blocks may be represented by fewer quads when possible.
Features
Greedy meshing algorithm
Uses a sweep-based approach to merge adjacent block faces during chunk mesh generation.Experimental performance optimization
In some scenarios, reducing the number of generated faces may decrease geometry complexity and GPU workload.Debug tools
Includes a wireframe/debug mode for visualizing generated chunk meshes.
Compatibility
- Designed for Fabric 1.21.11
- Because it modifies parts of the rendering pipeline, it may conflict with other rendering or shader-related mods.
Status
This project is experimental and intended primarily for testing greedy meshing techniques in Minecraft’s rendering pipeline. Performance improvements may vary depending on hardware, world geometry, and mod combinations.

Greedy Meshing server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.
Is Greedy Meshing compatible with fabric?
Greedy Meshing officially supports fabric for Minecraft 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Greedy Meshing – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Greedy Meshing consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
