Render using Autodesk Raytracer engine, not all the lights are on

[damon.sidel]

I'm experimenting with the Autodesk Ratracer engine and getting decent quick results for daytime renders. So I decided to try it on an interior night time render. It's OK, but not all the lights seem to be on! The lights in question are Revit OOTB "Downlight - Recessed Can".

Thoughts?

Dumb question but are you sure they're cutting the ceiling and that the light source is actually below the top of the fixture so it's not getting blocked.
Just a thought.

Not a dumb question... yes, they are all cutting the ceiling.
