I'm rendering a satellite in orbit of the Earth for a client. The sun is head-on so there is nothing to light the back of the satellite. Since this doesn't look great and more of the satellite should be visible, I want to make it so that shadowed areas aren't as dark. I tried doing this by making the world lighting brighter, which works, but since the satellite is metallic, the shadowed areas of the satellite don't look shadowed at all when viewed at a shallow angle (the background is reflected). How can I make the satellite still look shaded properly but with the shadowed areas still somewhat illuminated?
