Hi, I’m using
FMetaHumanCharacterEditorBuild::BuildMetaHumanCharacter(TNotNull<UMetaHumanCharacter*> InMetaHumanCharacter, const FMetaHumanCharacterEditorBuildParameters& InParams)
to export my MetaHuman character in cinematic form. The build logs show CharacterAssemblySucceeded, but when I open the generated Blueprint a breakpoint is hit and I get these logs:

What step am I missing? This is important for my work — any help, pointers, or things to check would be greatly appreciated. Thank you!
