Stable Creation Tools v1.9.1

Pack Merger

Intelligently merge multiple resource packs into one optimised pack.

Stable · Released and maintained. Version 1.9.1 covers 1.21–1.21.11 and experimental 26.x builds.

Why it exists

Purpose

Running many resource packs means manual load order, visual conflicts, and wasted texture slots. Pack Merger combines packs into a single optimised pack while automatically resolving conflicts — so you get the best of every pack without the clashes.

Who it's for

Resource pack users, texture artists, content creators, and server owners curating a consistent look.

Key capabilities

Intelligent merge engine

BFS/diff-based conflict detection finds and classifies every collision.

Automatic conflict resolution

Deterministic resolution rules decide which pack wins per asset.

In-game GUI

A visual screen for selecting packs and reviewing merges before export.

Version-correct export

Exports with the correct pack_format for the target Minecraft version.
