Thanks you guys for help. I tweaked this bottle a little, and I managed to get more or less good results. It turns out that turning on caustics and adding some absorption should make glass materials a lot better... a bit slower tough, but as for my first glass object in corona, I`m quite happy with the result:)

Firstly, there is no need to activate the diffuse channel for glass. Corona will render just fine without it. As for the double reflection, Is this not how it would be in real life?

Thank you. It looks quite ok, but if you will remove absorption from liquid (as for example in mineral water), those ugly reflection will start to show up. I noticed that absorption with colour is reducing all this reflections, but without any volumetrics it will start looking as in my pictures.

Yes, yes they are. Unfortunately, because I cant find any more obvoius problems, and these strange reflections are still there...

Hello there:)

I`m just trying to move from vray to Corona, but I stucked with this strange glass problem. I have some bottles that I need to render. Light setup is straight forward:
back light with some gradient
strong left light with gradient
right weaker light with some gradient

And there goes my bottles with very strange double reflections, that looks very weird. Can you give me a hint, what to do to make this glass look more clear?
I want to put inside this bottles some liquid, but when I do that, number of reflections increases and all is looking more and more strange...
