IES light duplicate

[stezza]

I have created a IES light from vray plugin and looks fine in the render.
When I go to duplicate this light with input connections enabled it does not want to render, only the first one works.
Do I have to go to Create>VRay>Create Light from vray plugin every time?

Also the browse button is missing I have to type in the IES file location.

Thanks

OK it works if I dont group the IES light gizmo with the lamps. If I group the lamp and it's light the select the group node and dulicate this seems to break.

Why dont you instace this around? Works better than mental ray ies and you change all ies lights with one attribute editor
