VrayLightDome Override Alpha

[gagui]

Hello!

Just wanted to note that this option seems not be doing anything.
If I check and lower the Alpha to 0 the dome light still renders with full alpha.

And there's another thing that I can't manage to archive. I have a transparent object and a dome light, how can I make the dome invisible in the background but keep the visibility through the transparent objects? I can't find a way to do it.
If I check Invisible in the dome light the dome is not visible through transparent objects.
Maybe adding a Refract Contribution paramenter is the solution... just guessing...

You could disable "Affect Alpha" in Advanced group of Dome Light, this will render the DomeLight but the alpha will "cut" it.
