I'm using Revit 2014. Whenever I render using artificial lights, the rendering progress dialog shows that all of the hundreds of lights in the project are being included.

The artificial lights selection dialog seems to have no effect. I can select some of the lights or even none at all, and revit still just renders all of them.

I've sucessfully rendered with selections of artificial lights in the same project in the past. I also had the same problem temporarily a couple days ago, but it fixed itself without me ever figuring out what was goign on.

Any ideas about what could be happening?

Best practice is to use light groups - read this help section:

Creating a section box around the geometry to be rendered seems to have worked for me. This is more than a adiquate workaround, becuase it's something you'd do anyway to make the rendering faster. I suspect that the proplem was caused by the lights being part of a model group as well as a light group.

I know exactly what you are dealing with. I had this problem for months and finally this trick worked for me. Not sure if it's right or wrong but worked for me. When you open the 'Artificial Lights' dialog box and you have all your grouped lights ticked. So before rendering, un-tick all the lights (doesn't matter grouped or not) and then tick them back on. I know this sounds funny and weird, but it worked for me. Believe. Is it a revit bug or some functionality that I don’t know yet, no answer?? Also, when you try let me know if it worked.
