I have an area light centered at the origin. I also have a partially 
transparent plane passing through the origin. However, the light is not 
illuminating this plane. How do I fix this? Thanks!

Have you tried area_illumination? Can't guarantee that it will help in
this very specific case, but it's worth a shot.
