What it does

WecuiFix is a Fabric mod that patches WorldEditCUI so it stops marking itself as incompatible with WorldEdit. The Modrinth page for the mod explains that the repair works by editing the WECUI jar and its fabric.mod.json, and that a manual change to the config file can bypass the compatibility check. Both WorldEdit and WorldEditCUI must be installed alongside it, and both are listed as required dependencies.

The mod is for players and server owners who use WorldEdit selections with the CUI display on Fabric. Installation covers the jar edit, optional version isolation under the minecraft folder, and a fabric loader dependencies file. The author notes state that newer releases of the two mods are compatible without this fix, so the mod targets the earlier range. It runs on the client only, so servers do not need it.

Key features

  1. Removes the incompatibility marker

    Strips the mark that tells Fabric the WorldEditCUI jar conflicts with WorldEdit, so both mods load together on supported versions.

  2. Manual config bypass

    Describes an edit to the WECUI config file that skips Fabric's compatibility check for users who prefer not to change the jar.

  3. Version isolation path

    Explains how to place the patched files in a version-specific config folder when version isolation is enabled in the launcher.
