I´m using refl. planes with vray light materials, but I don´t want light emitting from the planes. I´ve tried to use relf. planes with ordinary vray materals and output maps in the diffuse slot, but then I don´t get any reflections.
If you select the planes, right-click in the viewport and select V-Ray properties, there is a check-box “Visible to GI”. Uncheck this and you should be fine.
Best regards,

Ah.. I should have thought of that. Thanks.
