About this Mod

FastChest Reforged

This a Forge port of FastChest by fake_domi for Fabric, which the author has authorized. If you're looking for the Fabric version, please go to FastChest's GitHub repository, as the CurseForge page is no longer being updated.

DO NOT REPORT ISSUES IN THE FABRIC REPOSITORY. FAKE_DOMI IS NOT MAINTAINING FASTCHEST REFORGED, I AM. REFER TO THIS PROJECT'S ISSUE TRACKER.

If you have a lot of chests nearby, you have probably noticed how bad Minecraft is at rendering them. The more chests you place, the lower your FPS go.

This mod helps by removing dynamic models from chests and making them render as static chunk geometry like normal blocks. (This means they will lose their lid opening animation!)

Depending on how many chests you have around you'll see varying effectiveness. In large storage rooms this mod can easily double your FPS. Keep in mind this mod only focuses on chests, and there might be other things crippling your FPS.

FastChest works with Rubidium and Optifine and should be compatible with all other mods and resource packs that leave chests alone. One example that does not is the Vanilla Tweaks Proper Break Particles resource pack. 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.

Frequently Asked Questions

Does FastChest Reforged need to be installed on the Minecraft server?

No. Modrinth marks FastChest Reforged 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 Reforged require?

Use a file for forge and your exact Minecraft version. Supported versions include 1.21.3, 1.21.2, 1.21.1. Files for different loaders are not interchangeable.

FastChest Reforged 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.
