Overview

This document describes the complete workflow for modding inZOI character faces using MetaHuman Editor in Unreal Engine 5, and registering the finished assets in the ModKit.

MetaHuman Editor Limitations

Options set in the Materials and Hair & Clothing tabs of MetaHuman Editor are not reflected in the inZOI ModKit.

Joint Matching Popup

A joint matching popup will appear when the mesh is assigned. Select Yes.

Head Mesh Setup

Important: Head Mesh Setup

The head mesh has changed. The following setup scripts will run on the selected MetaHuman face skeletal mesh:

  1. Skeletal Joint Matching — Recalculates bone correspondence between the reference body and head skeletal meshes and may update bone transforms.
  2. LOD Cleanup — inZOI uses LOD 0–4. MetaHuman assets ship with LOD 0–7, so extra LODs will be removed and the mesh will be reorganized to match the inZOI LOD range.
  3. Material Replacement — Replaces all material slots with the inZOI in-game materials.

These operations write to skeletal mesh assets. Back up or verify version control state before continuing.

  1. Set the Thumbnail
