Vray for SketchUp? - A Black Art?
-
I am having the exact same problem and becoming really frustrated.. From some reason whenever I have tried to render with the rectangular light.. no light renders.. I have tried playing with the intensity and playing with physical camera (off and on) and nothing seems to be working.. Can anyone help??

iirc the intensity of the sun in vray is approx 364. To turn off thee Sun you need to untick Default light in the vray system rollout. Now you should see the effect off the rectangular light. try them with a intensity value of 200 to start with.
-
if the vray physical camera is on and less value for your rectangular light. you wont really see them. physical camera works together hand in hand with the the vray sun. if you are using night scene better to turn off the physical camera. all lights (omni or point lights, emmisive and rectangular lights will appear)
if you insist in using the camera try lowering your fstop value, decresing the shuterss speed or even makign your ISO higher, but lo be careful because if your using ISO more than 800, the image will become noisier.
