# IMPORTANT NOTICE

As of Unreal Engine 5.3, this plugin comes out of the box and is distributed and maintained by Epic in their fork. See [here](https://nfrechette.github.io/2023/09/17/acl_in_ue/) for details.

This repository will remain mostly read-only following the next minor release and only accept critical fixes. Contributions should instead be directed to the Unreal Engine main development repository where the ACL Plugin fork lives (under **Engine/Plugins/Animation/ACLPlugin**).

Support questions and requests should be directed to the Unreal Developer Network (UDN).

====================================================

# Animation Compression Library Unreal Engine Plugin

This plugin integrates the [Animation Compression Library](https://github.com/nfrechette/acl) version [v2.1.0](https://github.com/nfrechette/acl/releases/tag/v2.1.0) within [Unreal Engine 4 and 5](https://www.unrealengine.com/en-US/blog). It is suitable for every animation clip and platform as it features a low memory footprint, high accuracy, and very fast compression and decompression.

Compared to **UE 5.2.0**, the ACL plugin compresses up to **2.9x smaller**, is up to **2x more accurate**, up to **2x faster to compress**, and up to **6.3x faster to decompress** (results may vary depending on the platform and data).

The documentation on how to use it can be found [here](./Docs/README.md) along with performance results.

You can find the ACL plugin on the Unreal Marketplace [here](https://www.unrealengine.com/marketplace/en-US/product/animation-compression-library).
