Hello,
unfortunately, with Corona is impossible to render, correctly, liquid inside containers. Look at the images.
Also, with VRay I can achieve better (correctly) result in less time (VRay-RT GPU Nvidia 560GTX)
In Corona, water is dark.
(*) In my render I used a solid box for the water (PT+HD)
(*) The refraction color is perfect white

Old problem. For this you should use Bidir/VCM with solid refraction mode or set MSI to some high value or 0 and wait wait wait until it refines.
-
until you use specular light sources, you can get away with this by increasing MSI ;)

I know, it's old problem. Jut I found weird the shadow inside the container when I use Hybrid.

(*) I tried with 800 and 8000 MSI + progressive mode. I have dark shadows inside the container. It isn't like VRay.
(*) Bidir/VCM is just experimental right now.

So I guess hybrid mode doesn't cast direct shadows but blocks GI.

For twosided glass mode, keymaster used shadow model that subtracts some light based on the amount that got reflected by fresnel reflection. And i think he has used the same model for hybrid glass as well. In Vray, checking affect shadows just makes shadow transparent based on the amount of refraction, but does not take reflection into account.
