About this project

What does Pehkui Rebuilt add?

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.

  • 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

For introductory documentation on modifying entities via data packages, see DATAPACK-SCALE-RULES .

Modpack Use

Modpack use is welcome.

  • All other 1.21.x branches are full independent rebuild of mixin‑layer implementation.

Original Pehkui: https://modrinth.com/mod/pehkui

This project would not exist without Virtuoel’s work and the original Pehkui contributors.
