Chiro UE4

"Chiro UE4" is a Blender add-on for skinning with Unreal Engine 4 Mannequin armature.


Who is it for

  • 3D Artists, who want to skin their characters with the Mannequin skeleton
  • Indie Game Developers, who want an easy way to swap an armature of a mesh with the Mannequin skeleton

Why we need it

  • animation created for Mannequin may be reused
  • blueprints created for Mannequin may be reused
  • Mannequin skeleton may be reused

What it gives you

  • Free software (as in freedom)
  • Skinning with Mannequin compatible armatures
  • FBX export made easy (with correct scale)
  • Mixamo to Mannequin skeleton transformations automation
  • A bunch of automations

What it does not do

The primary goal of this add-on is to make Skinning easy. If you need to animate your characters, you should consider using EpicGames Blender Tools for that (e.g. Unreal to Rigify).
