Light unseen by camera ?

[simsen]

Hello,
is there a way to do this? "opacity" doesn't work since the light disappear in reflection and that's not what I want

thanks

if I understand You right You wan't to get reflection, but don't want scene to be lit. In that case I would try to have simple plane (with diffuse material: grey/white) & lit it up - It will still be seen in reflection of Your object, but light the scene less =) that what photographers in real world do when trying to balance reflections with amount of light in the scene. Just keep in mind if You go this route, it might take more time to render =)

yes, this is exactly what I you want. i've just found a way to do this: Uncheck "visible to camera". and then I put a diffuse material on the plane - as you suggest - and it works perfectly!
Thanks for your help
