Hi, I have a scene where i need a large Emissive Plane to be use as a fill light. But the problem is When i faded that plane the reflection still can see the emissive plane. If i chose hidden the light and the reflection gone. Any idea i can have the light on but don't want the camera and reflection to see the emissive plane? sorry for my poor english.

djingga - This is not possible within iray. Planes can only be blocked by primary rays so the emissive plane will also show up in a reflection and the effects (lighting/shadowing) from a plane are also always visible. You could accomplish what you are trying to do with two passes. Render one pass with the emissive plane enabled, then another pass with the plane disabled and in photoshop, mask the area the plane reflects with the rendering of the surface without the plane.

Hope this helps
