Pehkui Rebuilt: entity scaling and compatibility limits

03.11.2026 · Compatibility not verified

↓ Choose a version
Unofficial library for Pehkui API compatibility on Fabric/NeoForge, allowing entity size and collision box adjustments.

An unofficial Pehkui-compatible library

Pehkui Rebuilt maintains compatibility with the public Pehkui API on newer Minecraft versions. It can change entities’ visual size and collision boxes. It is not an official Virtuoel release.

Before installation

  • Remove the original Pehkui JAR: the author states that the two libraries cannot be used together.
  • Account for the beta status and test a pack before deploying it to a public server.
  • The author reports testing on small servers and in singleplayer, not large modpacks.

Datapacks and modpacks

Mod version 3.8.5 and later includes experimental datapack support for modifying entities. The author welcomes modpack use. Scale-rule instructions are provided in the project’s DATAPACK-SCALE-RULES document.
