# Introduction

**Tex Packer** is a channel packing tool designed specifically for Unreal Engine Editor. It empowers environment and technical artists to **pack**, **unpack**, or **re-map** texture channels in a single click, ensuring assets perfectly match any production pipeline.

Key features:

* Built on a high-performance C++ core with a lightweight Editor Utility Widget interface.
* Works directly with source texture data for **maximum quality**, unlike typical Blueprint-only solutions.
* Supports large-scale **batch repacking** across different texture formats and channel layouts in a single operation.
* Includes a built-in semantic texture format database with support for custom user-defined formats and **automatic recognition** based on naming patterns.

To start your workflow, begin with the [**Getting Started**](/getting-started.md) section.&#x20;
