      Hi All, I've followed all instructions to set up IES lights that I downloaded from the internet, but no matter how big I set the intensity to be, it just wouldn't show on the Frame Buffer...Help please!

        Intensity is top low. Take a test for about 800.000 and disable the sun.
        For every ies file you must set different intensity, there is nog ground rule for that.

          I turned off GI and changed the parameters in GI to be Primary Rays - Irradiance Map and Secondary Rays - None. It worked with one IES for a minute as attached photo but after me putting more IES lights even setting them at different intensity, they all disappear!! How frustrated... Still don't know what went wrong...

            Are the lights not connecting with the wall ? They should be free from the wall.

              Think about posting your skp file so people can have a look and see what is wrong. Also, CG released a new version, Vray 3.6. You should update, there are a lot of new features and bug fixes.

                Is this a trial version of Vray? In the past, with the trial, you could only have one light operable.
