PreciseMainHandSynchronizationMod
by Gerrygames
PreciseMainHandSynchronizationMod keeps the main hand that other players see in step with each player's own preference, so multiplayer scenes look the same to everyone.
What it does
The mod makes the main hand shown on each character match the preference its owner has set. When players hold weapons or tools during combat or joint building, the held item no longer appears on a mismatched side for some viewers. Once installed, the sync runs on its own and needs no setting to switch it on.
The mod is a client-side only Fabric mod, so only the player who installs it needs it; servers run without it and join unchanged. Installation means placing the JAR in the mods folder of the Minecraft client and restarting the client to apply it. Files are built for Fabric and cover 1.20.2 – 26.3 across 21 release versions, released under the MIT License and open source.
Public links exist for the source code and the issue tracker. The latest Fabric file is 1.0.6 for 26.3, dated 2026-09-17, and the mod was first published on 2023-12-01.
