Nice results Chakib ! The Juice looks awesome.
But take a look at the Straw, it's stills sharp even inside the fog. That's what's confusing me about this SSS workflow....
On a Dirt Water/Juice, or something like that, the rays are messed and sort blurred in real life, but inside a FOG or smoke the rays aren't messed too much, so the objects with sharp edges inside the volume looks ok, but it i miss the refraction of thoses rays... Maybe using Refraction Glossness is the way to make it looks right ?
