This tutorial walks you through a complete free workflow for bringing MetaHumans from Unreal Engine into Blender. In almost two hours of step by step guidance, I cover everything from creating and modifying MetaHumans, handling materials and grooms, to adding ARKit shape keys and transferring animations, giving you all the tools to customize and work with MetaHumans outside of Unreal.

Full Metahuman support without leaving Blender, from importing DNA files, sculpting meshes, editing base mesh, skeleton, facial expressions, BRF solver, etc.
