Vray Lighting not working

I’m new to Sketchup and Vray, I have managed to create a model but when I add lighting with the Vray tools, they come up as line shapes, not filled in as I’ve seen in tutorials. This means they also do not work.
Does anyone know how I can fix this?

Thanks,
Mara

Older tutorials using V-Ray version 2 show lights as filled in shapes. Since versions 3 (5 is the latest), the lights are just wireframe, or lines only. How do you know they do not work? Older tutorials using V-Ray version 2 show lights as filled in shapes. Since versions 3 (5 is the latest), the lights are just wireframe, or lines only. Did you do a test render? If so, please post a screen shot of what your render window (frame buffer) look like so someone can help further.

Also, before concluding that the lights do not work try increasing their brightness. Depending on the way units are set, the values in Vray needed for lights to show can be surprisingly large.

Thank you both for your quick replies, it seems it was just that the brightness was very low.
