Hi. I am on my way now to getting my first render in mental ray look ok. I had it set up with spotlights and thought I should try it with a directional light instead. Selected one of my lights and swapped it to directional.

Guess what? My whole scene turned into night. Everything is lit as before, but very dark. I jacked up the intensity from 1.2 to 10, and it is still just as dark.

Why? Doesn't directional lights work with mental ray?
