After the first render, when putting it together we noticed something. The Table was FLOATING! It wasn’t until the ambient occlusion was rendered that we seen the shadows under the table leg, making the gap from the ground really obvious.
Because the table is a big part of the scene and there is a few close ups we just had to rerender again. We had the time and decided to do it, hopefully we will get it right next time! We also took this as an opportunity to tweak the reflections on some of the diamonds so they were not too white.
