Troubleshooting¶

Problem	Check
Runtime conflict after updating	Save your work and restart Blender to load the updated runtime.
NumPy errors, or glTF import fails with "DLL load failed"	See NumPy errors after updating to 1.0.1.
Faceboard does not move the face	Check Character, then click Edit Board again.
Faceboard layout missing	Select faceboard.json from your Epic MetaHuman for Maya installation.
No ROM clips listed	Use exported FBX files, not Unreal .uasset files.
UV Conform rejected	Check compatible MetaHuman UVs and the Head/Body selection.
Creased ears, lips or eyelids	Check matching markers and protection. Try fewer Detail Iterations and compare from several angles.
Markers are invisible	Enable Show Markers.
Markers will not import	Set Source and Target; their topology must match the saved marker set.
Lower LOD still has the old shape	Apply the preview first. After manual sculpting, use Update LOD 1-7 and check any warnings.
Protection is hard to see	Click Protect to view the Source's painted mask.
Export blocked by a welded sculpt	Click Unweld Neck Seam first.

If Unweld reports changed topology or conflicting original meshes, keep the joined sculpt and recover from a saved copy. Do not delete your edits.
