About this Mod

If your storage room contains a lot of chests, you have probably noticed how bad Minecraft is at rendering them. The more chests are placed, the lower your FPS go.

FastChest helps by removing their dynamic models (aka BlockEntityRenderer) and making them render as static chunk geometry, like most normal blocks. (This means they will lose their lid opening animation! Check out Enhanced Block Entities if you care about that.)

Depending on how many chests you have around, you'll see varying effectiveness. In large storage rooms this mod can easily double your FPS, but keep in mind that chests aren't the only thing responsible for bad performance.

FastChest works with Sodium and Optifine and is compatible with resource packs that leave chests alone. For example, the Vanilla Tweaks Proper Break Particles resource pack doesn't. It overwrites the chest blockstate definitions and is not compatible out of the box. You can however delete chest.json, ender_chest.json and trapped_chest.json from the /assets/minecraft/blockstates directory of your resource pack to make it work with the mod.

There is a chance for chests from other mods to be broken by FastChest. This mod only supports vanilla chests.

A classic (full-block) chest resource pack can be downloaded from here.

Frequently Asked Questions

Does FastChest need to be installed on the Minecraft server?

No. Modrinth marks FastChest 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 FastChest require?

Use a file for fabric and your exact Minecraft version. Supported versions include 1.21.11, 1.21.10, 1.21.9. Files for different loaders are not interchangeable.

FastChest is not working – 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.
