Pehkui Rebuilt
Pehkui Rebuilt is an unofficial library maintaining compatibility with the Pehkui public API for newer Minecraft/Fabric versions. This mod can change the size of entities, including their collision boxes and visual size.
This is not an official Virtuoel release.
The goal of this project is to maintain Pehkui‑API‑compatible support for modern Minecraft Fabric releases, with fully rebuilt and flattened internal mixin implementations.
Supported Versions
Currently supported:
- Multiple Minecraft 1.21~26.3 Fabric/NeoForge
More versions may be added as development continues.
Beta Status
While it has not been tested in large-scale modpacks, comprehensive testing has been completed on small servers and in single-player mode.
Data Packs Support
Mod versions 3.8.5 and above have experimental data package support.
For introductory documentation on modifying entities via data packages, see DATAPACK-SCALE-RULES .
Modpack Use
Modpack use is welcome.
As these are beta builds, please perform thorough testing before deploying to large modpacks or public servers.
⚠️ Important: This library cannot be used alongside the original Pehkui. Remove the original Pehkui jar before installation.
