I did setup an easy scene with an area light behind a window. In the glass (simple plane) which is in front the area light is visible - how can I turn this off so that the background is shining throgh?

$\begingroup$ if you go to the object tab (orange cube) and then cycles settings and uncheck "Camera" does it solve your problem? $\endgroup$– user27460Commented Jul 28, 2017 at 11:44

1$\begingroup$ Hi Matt - wrong setting, but the right direction. If I turn off 'Transmission' in the cycles setting it does work ! Thanks for pushing me into the right direction ! $\endgroup$– ThorstenCommented Jul 28, 2017 at 12:34

Thanks to Matt this is now solved. In the Cycles Settings of the Area Light I turned off the setting for 'transmission' and therender shows what I want :)

$\begingroup$ Anyone know how to get this working in Blender 2.91? I want the light of an area light to affect the scene but don't want the are light's shape to appear on reflecting objects. Turning Transmission off for the light und Visibility doesn't do it. $\endgroup$ Commented Jan 6, 2021 at 12:41

$\begingroup$ Nevermind, found that it's the Glossy flag that switches this on/off. $\endgroup$ Commented Jan 6, 2021 at 12:44
