I'm just trying that right now, but for some reason the scene is
completely black.
I have absolutely no idea why. It's a time like this when I make stupid
mistakes which stall me for hours, when I forget something very, very,
simple.
Help!

  hf_gray_16     
  ini_option "+FT"

           ambient 1   
         }
