Cull Less Leaves Wiki

Cull Less Leaves is a lightweight client-side optimization mod that boosts frame rates around trees, jungles, and any dense foliage. It removes the hidden inner faces of leaf blocks — the quads buried inside a canopy that you can never actually see — so the game draws far fewer triangles in leaf-heavy areas.

Your forests still look exactly as full and natural as before; there is no visual difference to the leaves themselves. This is a 9Minecraft Studios port to Minecraft 26.2 and needs only Fabric API.

Vanilla renders leaf blocks with every face drawn, including the faces pressed up against neighbouring leaves deep inside a tree. Those interior faces are completely hidden by the outer leaves, yet the GPU still processes them.

Cull Less Leaves detects these buried faces and culls them from the render, cutting the quad count of a large canopy dramatically. The outer shell of the tree is untouched, so the foliage looks identical while the game has much less to draw — which shows up as higher, steadier FPS in wooded biomes.

1. Install Fabric Loader and Fabric API for Minecraft 26.2.
2. Drop the Cull Less Leaves jar into your mods folder.
3. Launch the game — the optimization applies automatically, no configuration required.

Because it is purely client-side, you only need it on your own client; it is not required on servers you join.

• Client-side only: join any vanilla or modded server without needing the mod there.
• Safe to add or remove: it changes nothing in your world saves, so you can install or uninstall it at any time.
• Best in forests: the FPS gain is largest in jungles, dark forests, and other dense-canopy biomes; open areas see little change because there are few hidden faces to cull.
• Low-end friendly: especially helpful on weaker GPUs where leaf rendering is a bottleneck.

Will my trees look different? No — only invisible interior faces are removed, so foliage looks the same.

Do I need it on the server? No, it is entirely client-side.

What does it require? Fabric Loader and Fabric API.

Is it safe to uninstall? Yes, it makes no changes to world data and can be removed anytime.
