Vray Lights

Can’t get rectangle lights to work with vray when rendering. I’ve tried 100 different settings combinations, i’ve tried moving the rectangle light, but no luck. (stupid forum will only allow me to post 1 image because im a new user (yawn))

the light source is the cinema screen

What are your settings under the ‘options’ section for that rectangle light?

So all the other lights work EXCEPT rectangle lights? Have you tried converting the screen face to a ‘Mesh’ light? Or alternatively, adding an ‘emissive’ material to the screen face?

Emissive Material:

Converted screen face (group) to Mesh Light:

You don’t have an idea how clever that might be?
