Revit 2015 export creates Autodesk Rendering Lights in NWC with missing IES file

[luke.johnson]

Here's what happens:

1. Electrical contractor uses Navisworks Exporter addin to export NWC file from Revit 2015 to 2015 NWC (recently upgraded from 2013)
2. The Light Source subcategory is turned off in the exporting Revit view
3. When the file is appended to Navisworks 2015 (SP3),  a missing reference dialog appears regarding IES files
4. After ignoring this error, hundreds of lights are still created in the Autodesk Rendering tab
5. There is no way to easily unselect or delete lights from Autodesk Rendering in Navisworks 2015 (!)
