Well, I have both CULL_NONE and normalflip always set to true since I need to see 2 lit sides always. And the problem is that setting backFaceNormalFlip to true kills both front and back lighting on the reflected geometry. Setting the flip flag to false, produces correct front side lighting, but then expectedly a black back face.
Actually, the interesting thing is that if rotation can correctly handle the appropriate CCW winding and normal flips, what is it about reflected geometry that causes the issue ?
