V-Ray lights not showing up in rendering

Extending SketchUp V-Ray for SketchUp
,

I’m new to Sketchup and V-Ray but trying to use it for work. I have a room drawn but the V-ray spotlights and dome light won’t show up in the rendering. I’ve tried the following:

  • Made sure all lights are enabled
  • Put the lights on a tag and make sure that tag is turned on
  • Purge all unnecessary files
  • Make sure the lights aren’t intersecting with the ceiling
  • Turning up the intensity of the lights
  • Turning up the ISO

What am I doing wrong? Here is a link to the project. Dropbox

What are you expecting to see?
I turned on Auto exposure and GPU rendering and I got this

Then I turned the sun and the dome light off, leaving only the spots on

What was the dome light supposed to do? It works like a second sun. To illuminate the ceiling luminaire I would use a sphere light or then convert it to a Mesh light.
