      When rendering geometry with normals facing up the Y axis, the lighting appears to be wrong with the PrincipaledMaterial. The attached image shows two models exhibiting this behavior. The "wood plane" is over exposed and the normal map is very apparent. With the "marble" looking stone platform on the top facing faces are white and washed out. This happens with all HDRI images test against and is reproduce able with any model with a face facing up.
