Wow, I never knew about that. Thank you!

That still won't allow you to render a mask which is affected by refraction.

Coming up against this limitation of Corona right now, albeit with reflections instead of refractions.  This is really a killer for me given the way I'm using Corona.  I know this has been asked for for years, any chance we'll see this implemented soon?  I'm trying to figure out workarounds so I don't have to switch to Vray.

I have to say, "Wow" on this too. I've been trying for a year to find a way to render masks behind glass and decided to read today to see if anyone ever solved it in a manner that didn't take too may extra contortions. I don't know when this switch showed up but "Visible in masks" is my new BFF.
