Hi Terry,

Welcome to the Forums,

I haven’t heard Nvidias Omniverse mentioned much here, so I’d consider also posting at Omniverse - NVIDIA Developer Forums

I’m not familiar with the UE → Omniverse pipeline. But I’d start with trying to simplify your Metahuman’s skin material as much as possible. (Specifically chopping out anything with MF_AnimatedMaps mentioned in the logs)

Cheers
