I'm afraid you might be right, but the User Manual for Vray for Sketchup said it would not show either at its source or in the object. I'll try to contact them, or keep working on it.

I am using Vray for Sketchup, rectangular lights. I have checked the invisible box, but they are still clearly showing as reflections in the wall nearby. Any help? Thank you.

I feel the same way - good to see your message. I am totally struggling with putting four chairs and a table in the scene - so slow! I registered for this website cause of your funny line. Revit and Autocad do not struggle with pieces of furniture the way Sketchup does! Still, I like Sketchup for other reasons.
