Invisible lights are visible in reflective materials

[Uwe Tilemann]

I'd like to use invisible lights as fill lights for arch-vis. But these lights are then visible in reflective materials. Also if I place a light source behind a glass material it's visible as a reflection.

This behaviour is not what I expect as long as the light is unchecked as "visible to camera". The only solution I've found so far is to use emissive objects with a render tag with only "Visible in diffuse" checked, but using lights would be more flexible.

Can someone enlighten me please ;-).

Many materials have a reflective component and the new PBR shader has always more or less rough reflections.
So indirect lights excluded from reflections would mess up all PBR materials.
There is no way to distinguish clear mirror reflections from those material components AFAIK.
So I'm afraid you'll have to put up with the emissive object workaround.
