I’ve seen a few posts in this regard about light rendering black on models. I have an app that loads in multiple sea3d models. Does anyone know what might cause a certain mesh of a model to render lights as black?

I’ve turned off all my point lights and left only the directional light and tried flipping normals with no luck. I’ve heard that it’s a graphics card bug but what’s even weirder is it only happens on one of my models in the scene. The others don’t have this issue. See attached.
