How to hide light shape source through transparent window in Cycles? Shape of area light becomes visible through the transparent window in Blender Cycles.
I would like to keep the lighting effects, but hide the source shape.
On 1st screen: we can see the steam and droplet I want to keep
2nd screen : unchecking transmission disable all lighting through window.
3rd screen : window is hidden; square shape is not rendered.

Any help will be appreciated !
One possible way is to use the Light Path node.

This hides transmission light - when light goes through glass
But keeps light dispersion - when light is scattered inside glass/waterdrops/steam

Example using a glass pane, Suzanne and a mesh light.
Note the light dispersion on the glass pane
