Making glows "behave" when lighting adjacent surface?

Hi all,

I'm having an issue where a glowing surface is not properly illuminating an adjacent object. Basically, a glowing lens of a light is not properly illuminating the inside edge of the opening.

I have most settings turned up pretty high. Any advice appreciated...

    Glow channel in the texture or anything glows? What are your render settings?

    Hi ManStan,

    Glow channel.

    Settings attached.

    If the lens is a single mesh; a separate part, and simple, you might try anything glows. You can use the glow channel of a shader to light a scene, but it's touchy and iffy.
    But your render settings for doing it are right.

    Tried it - not working. I think it has something to do with the fact that the faces I'm expecting to light are perpendicular to the emitter... is that possible?

    I think that be the answer.

    Image 2 was done with 2.2 gamma setting.

    Hm.... are those sitting on a white surface?

    The background was the default gray setting.

    The image below was done on a white background same.

    Try increasing photon count, maybe. That helps me sometimes when I have odd corners in lighting.

    Yeah, tried that - it was certainly cleaner, but the surfaces still weren't illuminated from the adjacent glowing / anything glows object.

    thanks-
