Ensure that the desired model itself is of high quality and ready to be imported. They are often used as a way of specifying which side of a surface points “inside” or “outside” (for example, when creating shells). Report. If you have the "shade UVs" option enabled, Maya will show flipped UV shells in red instead of blue. The normals have been averaged in maya using Normals > Average Normals from the Polygons menu set.

However, if I simply reverse the normals, the petals on far side won't show because they are pointing away from the camera. The only difference between Raw and the default Srgb is that with the latter, I get weird shading, but the detail is inverted either You can achieve what you want without solving the issue in the question. You can see the stamens not display correctly, because the normals of petals is pointing into the middle of the flower. I've set the bump node to tangent space normals, and the color correction of the file to Raw. If I duplicate the sleeve and mirror it by changing scale X to -1 and then freeze transformations, the normals will invert and I'd have to reverse them back, and in turn, inverting the normal mapping, same thing if I were to plainly Normals Color Generation.
