Faces on model are inverted despite not being inverted in Substance Painter

As the title implies, one of my models is acting weird. The faces appear inverted in Unreal but do not appear this way in Substance Painter 3D. I flipped the normals in Blender, and the opposite happened: they’re inverted in Substance, but not in Unreal. Either way, the lighting maps are totally borked. I’ve never had anything like this happen, so some help would be appreciated.
