Hidden self illum objects?

:smile: :o Quick question,
Having self illum objects like a ceiling casting light in a general fashion I find is great, but I dont want to render a self Illum ceiling I want to render the ordinary ceiling, can the self Illum ceiling be invisible and the ordinary one visible. :smile:
how is it done then?

try calculating the irradiance map with one roof then save it and change the roof then render with the saved irradiance map

of course. object propeties/ invisible to camera!

Much appreciated Chaps
