Modern Minecraft rendering is fast—but not always smart. Why render block entities and mobs that are hidden behind walls or ceilings and are completely out of sight, when you could just skip them entirely?

This mod introduces asynchronous path-tracing to efficiently determine what's actually visible to the player. By leveraging multiple CPU cores, it calculates line-of-sight visibility in real time and eliminates unnecessary draw calls for hidden block entities and entities.

The result?
Smarter rendering. Less overhead. More performance.

Screenshots / Media

Stage View
A direct comparison with and without EntityCulling active. Testing was conducted in Scarland (Hermitcraft Season 9) with render distance set to 16 chunks. The mods Sodium, Iris and ImmediatelyFast were used alongside EntityCulling, running on Minecraft 1.21.5 with the Fabric mod loader.

Known Issues

Client-side entities, commonly used by magic mods for animations, may not behave as expected. Whitelist the relevant entities via the config screen for tick culling and/or entity culling.

You’ll also need to whitelist block entities that render well beyond their normal bounds. Examples include the vanilla beacon, pulleys from Create, and certain Botania blocks.

FAQ

Does this need to be installed on the server?

No. This is a fully client-side mod and does not need to be installed on the server.

Will this affect mob behavior or farms?

No. The mod only skips rendering—not simulation. Mobs will continue to spawn, move, and drop items as expected. Your farms and other gameplay mechanics will remain unaffected.

I have "Use Entity Culling" enabled in Sodium - does this still help?

Yes! While Sodium performs basic visibility checks based on loaded chunks, this mod goes further. It analyzes the actual line-of-sight visibility, skipping entities that are within visible chunks but not actually visible to the player. It’s a much more aggressive and accurate approach.
