Does anyone know why Unreal Engine 5.0.3 imports all USD polygons with smoothed normals (catmull) , even if the USD smoothing flag is set to unsmoothed? I am importing the USD via the USD stage.

This is causing huge problems in our Maya to UE pipeline.

I exported the 3D scene from Maya with the USD smoothing option set to unsmoothed. I have checked the USD export in other USD viewers, and the normals are definitely hard.

Is there a switch in Unreal Engine to set the USD stage to not smooth USD imports?

Is the Unreal Engine USD import plugin broken?
