Light material in Ray-Switch

[maru]

Here is the scene + example. I made two "black" materials. One will occlude the light, and the other one uses rayswitch to let it glow.
I know that this is not a real solution, but it's the only one I could think of...

thanks a lot. Yes, that's working fine.
Can we conclude that GI-slot in combination with light-material behaves oddly?
I would love to hear what Ondra might have to say about this.

Behavior of rayswitch+light seems counter-intuitive, but let's wait for Ondrej's explanation. I already notified him.

this is limitation of the fake system, light emitters cannot be ray-switched. When you disable emission, you turn the light into self-illumination, which is computed differently and can be ray-switched
