## What it is
A collection of Blender addons from Epic Games that streamline the game development workflow between Blender and Unreal Engine. It includes Send to Unreal for one-click asset transfer and UE to Rigify for node-based animation retargeting.

## Use cases
- send Blender assets to Unreal Engine with one click
- retarget animations onto Unreal marketplace character assets
- author new animations for Unreal characters using Rigify rigs
- set up a Blender to Unreal game asset pipeline
- export rigged and animated characters from Blender to Unreal

## When to choose
- you use Blender for asset creation and Unreal Engine for game development
- you need to frequently transfer meshes, rigs, and animations between Blender and Unreal
- you want to retarget animations onto Unreal marketplace assets inside Blender

## When to avoid
- you use a DCC tool other than Blender
- your pipeline does not involve Unreal Engine
- you need a general-purpose Blender exporter unrelated to Unreal
