The Character DNA Addon allows you to import DNA files into Blender with a seamless 1-to-1 integration of the MetaHuman face board and body correctives via [OpenRigLogic](https://github.com/EpicGames/OpenRigLogic).

Now, you can work in Blender and push changes back to your Unreal project through your MetaHuman's DNA. [Get Now](https://polyhammer.com/character-dna-addon).

## Overview

Welcome to the project! We are working hard to make this the best solution for customizing MetaHumans for Unreal Engine. [Code contributions](https://docs.polyhammer.com/character-dna-addon/contributing/development/) and suggestions are welcome, and we are excited to work with the community to make this even better!

The base version of the addon is **FREE** and fully supports Blender import and export of `.dna` files. It also fully integrates Epic's OpenRigLogic evaluation system, providing a fast 1-to-1 integration of both the MetaHuman head and body components (just like Unreal Engine). This allows users to use powerful tools like [MetaHuman Animator](https://dev.epicgames.com/documentation/metahuman/metahuman-animator) to drive facial animation directly on their rigs in Blender. This is totally free, and you can install it from our extension server when you create an [account here](https://dashboard.portal.polyhammer.com/).

However, please consider [financially supporting](https://polyhammer.com/character-dna-addon) the project by purchasing the pro version. The pro version contains advanced DNA editors which allow individuals and studios to replace their entire custom MetaHuman pipeline with just Blender. We heavily rely on your support to keep this project going! Thank you!

> [!NOTE]
> The addon is in the final stages of the open beta. The pro version is discounted while in beta; however, purchasing it now still gets you access to lifetime updates.
