What is Unreal Skeleton to Rigify?

Unreal skeleton to Rigify is the add-on that generates Rigify from Unreal models.

• No messing with Blender's metarig, it's created automatically
• One-click - just select the original Unreal rig (it should be already imported with 3rd party add-on, check Requirements) and click "Generate Rigify"
• Rigify include IK and Face

How to install?

The installation procedure is the same as for other Blender add-ons. 

1. Go to Edit > Preferences... > Add-ons 
2. Click Install...
3. Select downloaded .zip archive unreal-skeleton-to-rigify.zip
4. Click the check box to activate the add-on

Requirements

To run this script you would also need 2 additional add-ons:

1. “Rigify”, a default rigging add-on from Blender, should be on by default
2. Blender add-on to import exported Unreal models https://raw.githubusercontent.com/Dene33/TModel/master/TModelAddon_NoIK.py Right-click, save as and install as ordinary Blender add-on (see the previous paragraph)
   
3. An add-on that export models from Unreal games
4. Add-on works only on Windows

Only Blender 3+ is supported.

How it works?

1. Import Unreal model to Blender

First, one needs to import a Unreal model to Blender. There are a couple of apps that you can find in the internet.

2. Convert Unreal model to Rigify

Now you should have the Rigify add-on turned on, Unreal Skeleton to Rigify add-on installed and the original Unreal model imported to Blender.

1. Select the original Unreal rig imported to Blender. Rig is the Armature object, not the mesh

2. In the N menu, select Rigify from Unreal tab and with the Unreal armature selected, press “Generate Rigify”
