HotPatcher is an Unreal Engine (UE4.21–UE5) editor plugin for managing hot update versions and packaging resource patches. It tracks asset changes against a base release, supports multi-platform Cook and Pak patch generation, chunking, dependency analysis, and CI/CD integration via commandlets.

Use cases

• create hot update patches for unreal engine games
• package UE4/UE5 asset patches for multiple platforms
• diff asset versions and build incremental patches
• bundle non-asset files like lua scripts into pak files
• automate UE patch builds in CI/CD pipelines
• audit and optimize game package size
• split base package and manage chunks in Unreal Engine

When to choose

• you need a mature, battle-tested hot update solution for Unreal Engine used by shipped commercial games
• you want version tracking, diffing, and multi-platform patch packaging in one tool
• you need commandlet support to integrate patching into automated build pipelines
• your project is blueprint-based or uses a C++ architecture designed for content-only hot updates

When to avoid

• you need to hot-update C++ code itself, which this tool cannot do
• you are not using Unreal Engine
• you need a full client-side patch download and application runtime, which you must build separately
• you plan to resell or repackage the plugin commercially, which its license forbids
