Yes, VARIAN, but I was puzzled from stars in the sky: maybe they increase files. But the problem is the same 2uth a 48 Kb file with a scene with standard daylight, sun an camera to north, one cube with the standard checkboard material (it is a object oriented material). Rotate the cube each time of 90 degrees in the top view and you (I !) will have 2 faces with a lighter light and 2 faces with a darker light (same if you rotate in the side view). And this don't happen if I make the same with my old Vue 2
