I managed to export the metahuman head into blender, then back into UE and get the rig working again. Here’s the whole process:
- Export Metahuman Head from UE with next options:
- Download FBX Converter: https://images.autodesk.com/adsk/files/fbx20132_converter_win_x64.exe
- Open Converter and convert exported fbx file:
- Import converted fbx to blender with next options:
- Sculpt model in blender as you want.
- Click on root in outliner and click Alt + P, then “Clear and Keep Transformation”. Delete empty.
- Select All Objects in scene and export model from blender in fbx format with next options:
- Import fbx to UE with next options:
- Open imported mesh in UE and original Metahuman Head.
- Copy all setting from original head to imported.
- Asset User Data the most important option. You need to Copy it and Paste to imported Head. I tried to manually add the same options and it’s doesn’t work. So copy and just paste.
- Everything should work
