About this Mod
๐ What is Cullify?
Cullify is a client-side mod that culls decorative vegetation blocks (such as grass, flowers, ferns, algae, and kelp) based on distance from the player and customizable geometric shapes. By preventing distant or non-visible vegetation blocks from rendering, it reduces rendering load (vertex throughput and draw calls) without altering or removing the actual blocks in the world.

โจ Features
- โ๏ธ Vegetation Culling โ Reduces rendering load by hiding vegetation blocks that are beyond a configured distance.
- ๐ 8 Geometric Culling Shapes โ Customizable boundaries to control culling behavior around the player.
- ๐ LOD Density Filter โ Deterministic, hash-based density filtering that thins out outer vegetation (75%, 50%, or 25%) to save CPU overhead near the boundary.
- ๐ฟ Double-Tall Vegetation Support โ Synchronizes culling between the bottom and top halves of double-tall blocks (like sunflowers or tall grass) to prevent visual discrepancies.
- โ๏ธ In-Game Config Menu โ A configuration screen accessible via the
Kkeybind, chat commands, or the NeoForge mods menu. - ๐ Real-Time Statistics HUD โ On-screen overlay tracking culled blocks, water replacements, chunk updates, and draw calls.
- ๐งช Native Sodium Compatibility โ Direct hooks into Sodium's internal LevelSlice rendering pipeline and Sodium Options API.
๐ Geometric Culling Shapes
Unlike traditional culling mods, Cullify offers flexible mathematical boundary checks on both the horizontal plane (X/Z) and the vertical axis (Y):
| Icon | Shape | Geometry Mode | Description |
|---|---|---|---|
| ๐ข | Sphere | 3D Sphere | Culls blocks outside a 3D spherical radius. |
| ๐ | Cylinder | Cylinder | Culls blocks outside a horizontal circular radius (infinite Y). |
| ๐ฆ | Box | 3D Box | Culls blocks outside a 3D cubical bounding box. |
| ๐บ | Triangle | Triangle | Culls blocks outside an equilateral triangular boundary centered on the player. |
| โฌก | Hexagon | Hexagon | Culls blocks outside a hexagonal boundary. |
| โญ | Star | Star | Culls blocks outside a 6-point star (union of two intersecting triangles). |
| โน๏ธ | Square | Square | Culls blocks outside a flat square grid. |
| ๐ต | Circle | Circle | Culls blocks outside a flat horizontal circular boundary. |

Does Cullify need to be installed on the Minecraft server?
No. Modrinth marks Cullify as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.
Which version and loader does Cullify require?
Use a file for fabric, forge, neoforge and your exact Minecraft version. Supported versions include 26.1.2, 1.21.1, 1.20.1. Files for different loaders are not interchangeable.
Cullify is not working โ what should I check?
First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
