Man vs Machine recently completed this project for Pepsi.

I have been trying to render a similar look using a setup that involves adjusting adsorption in the materials and setting the IOR for the cola @ 1.33 and the bubbles @ 1.0 but I can never get anywhere close to this look.

Does anyone know if this look can be achieved with Mantra?  If so, can you offer some advice on how to achieve this look?

Thanks in advance.

I bet a lot of money this look came from comp more than from anyone render engine. It looks heavily modified.

Last time I looked into shading fluids it was done with a combination of surface hull and bubbles with nested dielectrics enclosing a uniform volume. Roughly like this:

Why don't you publish your attempt so we have something more elaborate to start from?

I tried using nested dielectrics and absorption.

if you force specular of air bubbles you would get those sharp highlights as well.

You should increase a bit the render quality maybe, I'm on a laptop.

Here's my try at it.  I reversed the faces of the bubbles, then merge them with the main/outer fluid mesh.
