heya; what dont you understand about the diagram, silver? it isn't that hard.... see the lights? that shows which way the sun light is pointing (its a circle with an arrow sticking out, right? this is the top view). so if you want the light pointing from the left, that is 90 degrees in the sun light's roll box. (in the rotation tab, you know, yaw, pitch, roll?) when the sun is to the left (of the top view), its azimuth setting is 0. to point your camera towards the left, you set its roll to -90. when you set the 2 mixed materials to 90, then material #2 will face to the right, towards your camera. hint: make an empty vue scene, then point the camera to 180, so it is facing 'up' in the top view. save this as your default scene, and never use the 'default' camera position of some kinda 45 degree angle setting. (it's much easier when the camera is parallel with the universe 'walls'!) if you want everything to be to the 'east,' use those numbers on the right. see? (maybe?)
